||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions

||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

## Install
|
||||
|
||||
- When Vouch is started
|
||||
- Connections to beacon nodes are established
|
||||
- Signers are initialised
|
||||
- Initial state of the network is ascertained
|
||||
### Binaries
|
||||
|
||||
- When notification of a new epoch arrives
|
||||
- Beacon block proposer goroutine is spun off
|
||||
- Beacon block attester goroutine is spun off
|
||||
Binaries for the latest version of Vouch can be obtained from [the releases page](https://github.com/attestantio/vouch/releases/latest).
|
||||
|
||||
- When a beacon block proposer goroutine starts
|
||||
- Fetch the expected block proposals for the current epoch
|
||||
- Spin off a goroutine for each proposal for which we are responsible
|
||||
### Docker
|
||||
|
||||
- When a beacn block proposal goroutine starts
|
||||
- Wait until appropriate time
|
||||
- Fetch details for the block
|
||||
- Create the block
|
||||
- Publish the block
|
||||
You can obtain the latest version of Vouch using docker with:
|
||||
|
||||
- When a chain reorganisation is notified
|
||||
- Beacon block proposer goroutine is notified
|
||||
- Beacon block attester goroutine is notified
|
||||
```
|
||||
docker pull attestant/vouch
|
||||
```
|
||||
|
||||
- When a beacn block proposer goroutine is notified of a chain reorganisation
|
||||
- Fetch the updated block proposals for the current epoch
|
||||
- Notify the relevant

# Account managers
|
||||
Account managers are the interface between Vouch and the accounts for which it validates. Account managers provide the list of validating accounts and carry out signing operations.
|
||||
|
||||
Vouch currently supports two account managers: Dirk and wallet.
|
||||
|
||||
## `dirk`
|
||||
The `dirk` account manager obtains account information from [Dirk](https://github.com/attestantio/dirk), and uses Dirk for remote signing. It is important to understand that this account manager never holds the private keys, instead it sends the data to sign to the Dirk server, which carries out signing as well as slashing prevention.
|
||||
|
||||
The basic configuration for using Dirk is as follows:
|
||||
|
||||
```YAML
|
||||
accountmanager:
|
||||
dirk:
|
||||
endpoints:
|
||||
- signer.example.com:8881
|
||||
client-cert: file:///home/me/certs/validator.example.com.crt
|
||||
client-key: file:///home/me/certs/validator.example.com.key
|
||||
ca-cert: file:///home/me/certs/ca.crt
|
||||
accounts:
|
||||
- my valdiators
|
||||
```
|
||||
|
||||
Each item is explained in more detail below.
|
||||
|
||||
### endpoints
|
||||
`endpoints` is a list of addresses that host Dirk servers that can respond to your requests. There can be multiple Dirk servers, for example:
|
||||
- the servers hold different accounts
|
||||
- the servers are part of a signing threshold group
|
||||
|
||||
At least one endpoint is required for the Dirk account manager.
|
||||
|
||||
### client-cert
|
||||
Dirk requires all clients to use certificates to identify themselves. Creating these certificates is detailed in the relevant [Dirk documentation](https://github.com/attestantio/dirk/blob/master/docs/getting_started.md#creating-certificates). `client-cert` is the client certificate that identifies this Vouch instance. This is required.
|
||||
|
||||
### client-key
|
||||
`client-key` is the client key that identifies this Vouch instance. This is required.
|
||||
|
||||
### ca-cert
|
||||
`ca-cert` is the certificate of the certificate authority by Dirk to sign the client certificate. This is required if Dirk is using its own certificate authority to generate client certificates (which is the usual case).
|
||||
|
||||
### accounts
|
||||
`accounts` is a list of accounts that Vouch will request from Dirk. This is an account specifier, and can be supplied in various forms for example:
|
||||
|
||||
- **`wallet`** will return all accounts in _wallet_
|
||||
- **`wallet/Validator.*`** will return all accounts in _wallet_ starting with _Validator_
|
||||
- **`wallet/Validator.*[02468]`** will return all accounts in _wallet_ starting with _Validator_ and ending in an even number
|
||||
|
||||
At least one account specifier is required for the Dirk account manager.
|
||||
|
||||
## `wallet`
|
||||
The `wallet` account manager obtains account information from local wallets, and signs locally. It supports wallets created by [ethdo](https://github.com/wealdtech/ethdo).
|
||||
|
||||
The basic configuration for using wallet is as follows:
|
||||
```YAML
|
||||
accountmanager:
|
||||
wallet:
|
||||
locations:
|
||||
- /home/me/wallets
|
||||
accounts:
|
||||
- my valdiators
|
||||
passphrases:
|
||||
- file:///home/me/secrets/passphrase
|
||||
```
|
||||
|
||||
Each item is explained in more detail below.
|
||||
|
||||
### locations
|
||||
`locations` is the list of locations to search for local wallets.
|
||||
|
||||
If no locations are supplied, the [default location for wallets](https://github.com/wealdtech/go-eth2-wallet-store-filesystem#usage) will be used.
|
||||
|
||||
### accounts
|
||||
`accounts` is the list of accounts that Vouch will request from Dirk. This is an account specifier, and can be supplied in various forms for example:
|
||||
|
||||
- **`wallet`** will return all accounts in _wallet_
|
||||
- **`wallet/Validator.*`** will return all accounts in _wallet_ starting with _Validator_
|
||||
- **`wallet/Validator.*[02468]`** will return all accounts in _wallet_ starting with _Validator_ and ending in an even number
|
||||
|
||||
At least one account specifier is required for the Dirk account manager.
|
||||
|
||||
### passphrases
|
||||
`passphrases` is a list of passphrases that will be used to unlock the accounts. Each item in the list is a [Majordomo](https://github.com/wealdtech/go-majordomo) URL.

# Configuration
|
||||
Vouch can be configured through environment, command-line or configuration file. In the case of conflicting configuration the order of precedence is:
|
||||
|
||||
- command-line; then
|
||||
- environment; then
|
||||
- configuration file.
|
||||
|
||||
# The configuration file
|
||||
Vouch's configuration file can be written in JSON or YAML. The file can either be in the user's home directory, in which case it will be called `.vouch.json` (or `.vouch.yml`), or it can be in a directory specified by the command line option `--base-dir` or environment variable `VOUCH_BASE_DIR`, in which case it will be called `vouch.json` (or `vouch.yml`).
|
||||
|
||||
A sample configuration file in YAML with is shown below:
|
||||
|
||||
```
|
||||
# log-file is the location for Vouch log output. If this is not provided logs will be written to the console.
|
||||
log-file: /home/me/vouch.log
|
||||
# log-level is the global log level for Vouch logging.
|
||||
log-level: Debug
|
||||
|
||||
# beacon-node-address is the address of the beacon node. Can be prysm, lighthouse, teku
|
||||
beacon-node-address: localhost:4000
|
||||
|
||||
# metrics is the module that logs metrics, in this case using prometheus.
|
||||
metrics:
|
||||
prometheus:
|
||||
# log-level is the log level for this module, over-riding the global level.
|
||||
log-level: warn
|
||||
# listen-address is the address on which prometheus listens for metrics requests.
|
||||
listen-address: 0.0.0.0:8081
|
||||
|
||||
# graffiti provides graffiti data. Full details are in the separate document.
|
||||
graffiti:
|
||||
static:
|
||||
value: My graffiti
|
||||
|
||||
# strategies provide advanced strategies for dealing with multiple beacon nodes
|
||||
strategies:
|
||||
beaconblockproposal:
|
||||
# style can be 'best', which obtains blocks from all nodes and compares them, or 'first', which uses the first returned
|
||||
style: best
|
||||
# beacon-node-addresses are the addresses of beacon nodes to use for this strategy.
|
||||
beacon-node-addresses:
|
||||
- localhost:4000
|
||||
- localhost:5051
|
||||
- localhost:5052
|
||||
```
|
||||
|
||||
## Logging
|
||||
Vouch has a modular logging system that allows different modules to log at different levels. The available log levels are:
|
||||
|
||||
- **Fatal**: messages that result in Vouch stopping immediately;
|
||||
- **Error**: messages due to Vouch being unable to fulfil a valid process;
|
||||
- **Warning**: messages that result in Vouch not completing a process due to transient or user issues;
|
||||
- **Information**: messages that are part of Vouch's normal startup and shutdown process;
|
||||
- **Debug**: messages when one of Vouch's processes diverge from normal operations;
|
||||
- **Trace**: messages that detail the flow of Vouch's normal operations; or
|
||||
- **None**: no messages are written.
|
||||
|
||||
### Global level
|
||||
The global level is used for all modules that do not have an explicit log level. This can be configured using the command line option `--log-level`, the environment variable `VOUCH_LOG_LEVEL` or the configuration option `log-level`.
|
||||
|
||||
### Module levels
|
||||
Modules levels are used for each module, overriding the global log level. The available modules are:
|
||||
|
||||
- **accountmanager** access to validating accounts
|
||||
- **attestationaggregator** aggregating attestations
|
||||
- **attester** attesting to blocks
|
||||
- **beaconcommitteesubscriber** subscribing to beacon committees
|
||||
- **beaconblockproposer** proposing beacon blocks
|
||||
- **chaintime** calculations for time on the blockchain (start of slot, first slot in an epoch _etc._)
|
||||
- **controller** control of which jobs occur when
|
||||
- **graffiti** provision of graffiti for proposed blocks
|
||||
- **majordomo** accesss to secrets
|
||||
- **scheduler** starting internal jobs such as proposing a block at the appropriate time
|
||||
- **strategies.submitter** decisions on how to submit information to multiple beacon nodes
|
||||
- **strategies.beaconblockproposer** decisions on how to obtain information from multiple beacon nodes
|
||||
|
||||
This can be configured using the environment variables `VOUCH_<MODULE>_LOG_LEVEL` or the configuration option `<module>.log-level`. For example, the controller module logging could be configured using the environment variable `VOUCH_CONTROLLER_LOG_LEVEL` or the configuration option `controller.log-level`.

# Getting started
|
||||
This document provides steps to set up a Vouch instance using validators in a local wallet.
|
||||
|
||||
It assumes there is a local wallet called "Validators" that has been created by `ethdo`, that the wallet has one or more accounts in it, and that those accounts have been configured as validators on an Ethereum 2 network.
|
||||
|
||||
It also assumes there is an accessible instance of the Ethereum 2 beacon chain that is fully synced with the current state of the chain.
|
||||
|
||||
#### Configuring Vouch
|
||||
A basic configuration file can be created in the user's home directory with the name `.vouch.yml` and the following contents:
|
||||
|
||||
```YAML
|
||||
beacon-node-address: localhost:4000
|
||||
accountmanager:
|
||||
wallet:
|
||||
accounts:
|
||||
- Validators
|
||||
passphrases:
|
||||
- secret
|
||||
```
|
||||
|
||||
`beacon-node-address` should be changed to access a suitable beacon node (Prysm, Lighthouse or Teku).
|
||||
|
||||
`secret` should be changed to be the passphrase you used to secure the accounts.
|
||||
|
||||
#### Starting Vouch
|
||||
|
||||
To start Vouch type:
|
||||
```
|
||||
$ vouch
|
||||
{"level":"info","version":"v0.6.0","time":"2020-09-25T14:46:45+01:00","message":"Starting vouch"}
|
||||
{"level":"info","time":"2020-09-25T14:46:46+01:00","message":"Starting standard submitter strategy"}
|
||||
{"level":"info","time":"2020-09-25T14:46:46+01:00","message":"Starting simple beacon block proposal strategy"}
|
||||
{"level":"info","service":"controller","impl":"standard","accounts":2,"time":"2020-09-25T14:46:46+01:00","message":"Initial validating accounts"}
|
||||
{"level":"info","time":"2020-09-25T14:46:46+01:00","message":"All services operational"}
|
||||
```
|
||||
|
||||
|
||||
At this point Vouch is operational and validation for the configured validators should begin.

# Graffiti providers
|
||||
|
||||
## Static
|
||||
The static graffiti provider uses the same single value for all proposed blocks. The graffiti is supplied in the "graffiti.static.value" configuration parameter. For example, to specify the graffiti "my graffiti" in a YAML configuration file the configuration would be:
|
||||
|
||||
```YAML
|
||||
graffiti:
|
||||
static:
|
||||
value: my graffiti
|
||||
```
|
||||
|
||||
Note that Ethereum 2 block graffiti is a maximum of 32 bytes in length.
|
||||
|
||||
## Dynamic
|
||||
The dynamic graffiti provider uses a majordomo URL to obtain one or more values for proposed blocks. The graffiti is supplied in the "graffiti.dynamic.location" configuration parameter. For example, to fetch graffiti from the file "/home/me/graffiti.txt" in a YAML configuration file the configuration would be:
|
||||
|
||||
```YAML
|
||||
graffiti:
|
||||
dyanmic:
|
||||
location: file:///home/me/graffiti.txt
|
||||
```
|
||||
|
||||
The location is a [majordomo](majordomo.md) URL. It re-evalulated each time a block is proposed, so if in the above example the contents of the file change the graffiti in the next proposed block will alter likewise.
|
||||
|
||||
The dynamic graffiti provider has a number of additional features. Firstly, the majordomo URL undergoes variable replacement. The variables that are available for replacement are:
|
||||
|
||||
- {{SLOT}} the slot of the block being proposed
|
||||
- {{VALIDATORINDEX}} the index of the validator proposing the block
|
||||
|
||||
For example, if the majordomo URL was `file:///home/me/graffiti-{{VALIDATORINDEX}}.txt` then a block being propopsed by validator 15 would result in the majordomo URL `file:///home/me/graffiti-15.txt` being used to fetch the graffiti.
|
||||
|
||||
Once the majordomo URL has been resolved the resultant data is separated in to multiple lines (blank lines are removed). If there is more than one line in the data then one of the lines is picked at random (note that vouch retains no memory of which lines have or have not been selected, so it is possible for the same line to be picked multiple times before another line is picked once).
|
||||
|
||||
The graffiti line also undergoes variable replacement, as per above. At this point the final result is used as the graffiti for the proposed block.
|
||||
|
||||
Note that Ethereum 2 block graffiti is a maximum of 32 bytes in length.

# Majordomo
|
||||
|
||||
Vouch uses [majordomo](https://github.com/wealdtech/go-majordomo) for many of its data fetching features. This document describes the supported confidants, and their configuration options.
|
||||
|
||||
## Direct confidant
|
||||
The direct confidant supplies values directly within the URL. The format of the URL is `direct://key`. For example, the URL `direct://Text` would provide the value "Text".
|
||||
|
||||
The direct confidant is configured automatically by Vouch.
|
||||
|
||||
## File confidant
|
||||
The file confidant fetches values from the location specified by URL. The format of the URL is `file://key` For example, the URL `file:///home/me/file.txt` would provide the contents of the file "/home/me/file.txt".
|
||||
|
||||
The file confidant is configured automatically by Vouch.
|
||||
|
||||
## Google Secret Manager confidant
|
||||
The Google Secret Manager (GSM) confidant fetches values from [Google Secret Manager](https://cloud.google.com/secret-manager). The format of the URL is `gsm://id@project/key` For example, the URL `gsm:///me@myproject/mysecret` would provide the contents of the secret labelled "mykey" in the project "myproject".
|
||||
|
||||
The GSM confidant has two configuration options. Credentials are required to allow majordomo to access the secrets. These are service account credentials in JSON format, available from the Google cloud console. The path to the credentials file is supplied in the "majordomo.gsm.credentials" configuration parameter.
|
||||
|
||||
The second configuration option is the project ID. This is optional, and can be supplied directly in the majordomo URL if required as seen above. If the project ID is supplied as a configuration option the majordomo URL can be shorted to the form `gsm://id/key`.
|
||||
|
||||
For example, to specify the GSM credentials and project in a YAML configuration file the configuration would be:
|
||||
|
||||
```YAML
|
||||
majordomo:
|
||||
gsm:
|
||||
credentials: /home/me/gsmcredentials.json
|
||||
project: my_project
|
||||
```
|
||||
|
||||
## AWS Secrets Manager confidant
|
||||
The AWS Secrets Manager (ASM) confidant fetches values from [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/). The format of the URL is `asm://id:secret@region/key` For example, the URL `asm:///AKIAITXFKX5JWOXJDJKA:8R06MHGKayTFHkuK8@eu-central-1/mysecret` would provide the contents of the secret "mysecret" from the region "eu-central-1".
|
||||
|
||||
The ASM confidant has three configuration options. Region is required to inform majordomo form where to fetch secrets. This is an Amazon region, such as "us-east-1" or "ap-southeast-2". The region is supplied in the "majordomo.asm.region" configuration parameter.
|
||||
|
||||
The second and third configuration options are the ID and secret of an AWS account that has access to read the secrets. These values are supplied in the "majordomo.asm.id" and "majordomo.asm.secret" configuration parameters, respectively.
|
||||
|
||||
If the parameters are supplied in the configuration they are not required to be supplied in the majordomo URL as well. If all parameters are supplied in the configuration then the URLs can simply be of the form `asm://key`.
|
||||
|
||||
For example, to specify the ASM credentials and region in a YAML configuration file the configuration would be:
|
||||
|
||||
```YAML
|
||||
majordomo:
|
||||
asm:
|
||||
id: AKIAITXFKX5JWOXJDJKA
|
||||
secret: 8R06MHGKayTFHkuK8
|
||||
region: eu-central-1
|
||||
```

# Prometheus metrics
|
||||
vouch provides a number of metrics to check the health and performance of its activities. vouch's default implementation uses Prometheus to provide these metrics. The metrics server listens on the address provided by the `metrics.address` configuration value.
|
||||
|
||||
## Health
|
||||
Health metrics provide a mechanism to confirm if vouch is active. Due to vouch's nature there are multiple metrics that can be used to provide health and activity information that can be monitored.
|
||||
|
||||
`vouch_start_time_secs` is the Unix timestamp at which vouch was started. This value will remain the same throughout a run of vouch; if it increments it implies that vouch has restarted.
|
||||
|
||||
`vouch_epochs_processed_total` the number of epochs vouch has processed. This number resets to 0 when vouch restarts, and increments every time vouch starts to process an epoch; if it fails to increment it implies that vouch has stopped processing.
|
||||
|
||||
`vouch_accountmanager_accounts_total` is the number of accounts for which vouch is validating. This metric has one label, `state`, which can take one of the following values:
|
||||
- `unknown` the validator is not known to the Ethereum 2 network
|
||||
- `pending_initialized` the validator is known to the Ethereum 2 network but not yet in the queue to be activated
|
||||
- `pending_queued` the validator is in the queue to be activated
|
||||
- `active_ongoing` the validator is active
|
||||
- `active_exiting` the validator is active but stopping its duties
|
||||
- `exited_unslashed` the validator has exited without being slashed
|
||||
- `exited_slashed` the validator has exited after being slashed
|
||||
- `withdrawal_possible` the validator's funds are applicable for withdrawal (although withdrawal is not possible in phase 0)
|
||||
|
||||
Vouch will attest for accounts that are either `active_ongoing` or `active_exiting`. Any increase in `active_exiting` should be matched with valid exit requests. Any increase in `active_slashed` suggests a problem with the validator setup that should be investigated as a matter of urgency.
|
||||
|
||||
There are also counts for each process. The specific metrics are:
|
||||
|
||||
- `vouch_beaconblockproposal_process_requests_total` number of beacon block proposal processes;
|
||||
- `vouch_attestation_process_requests_total` number of attestation processes;
|
||||
- `vouch_beaconcommitteesubscription_process_requests_total` number of beacon committee subscription processes; and
|
||||
- `vouch_attestationaggregation_process_failure_total` number of attestation aggregation processes.
|
||||
|
||||
All of the metrics have the label "result" with the value either "succeeded" or "failed2. Any increase in the latter values implies the validator is not completing all of its activities, and should be investigated.
|
||||
|
||||
## Performance
|
||||
Performance metrics provide a mechanism to understand how quickly vouch is carrying out its activities. The following information is provided:
|
||||
|
||||
- `vouch_beaconblockproposal_process_duration_seconds` time taken to carry out the beacon block proposal process;
|
||||
- `vouch_attestation_process_duration_seconds` time taken to carry out the attestation process;
|
||||
- `vouch_beaconcommitteesubscription_process_duration_seconds` time taken to carry out the beacon committee subscription process; and
|
||||
- `vouch_attestationaggregation_process_duration_seconds` time taken to carry out the attestation aggregation process.
|
||||
|
||||
These metrics are provided as histograms, with buckets in increments of 0.1 seconds up to 1 second.
|
||||
|
||||
## Operations
|
||||
Operations metrics provide information about numbers of operations performed. These are generally lower-level information that can be useful to monitor activities for fine-tuning of server parameters, comparing one instance to another, _etc._
|
||||
|
||||
Vouch's job scheduler provides a number of metrics. The specific metrics are:
|
||||
|
||||
- `vouch_scheduler_jobs_scheduled_total` number of jobs scheduled;
|
||||
- `vouch_scheduler_jobs_cancelled_total` number of jobs cancelled; and
|
||||
- `vouch_scheduler_jobs_started_total` number of jobs started. This has a label `trigger` which can be "timer" if the job ran due to reaching its designated start time or "signal" if the job ran due to being triggered before its designated start time.
|
||||
|
||||
## Client operations
|
||||
Client operations metrics provide information about the response time of beacon nodes, as well as if they returned
|
||||
|
||||
`vouch_client_opeation_duration_seconds` is provided as a histogram, with buckets in increments of 0.1 seconds up to 4 seconds. It has two labels:
|
||||
|
||||
- `proposer` is the endpoint for the operation
|
||||
- `operation` is the operation that took place (_e.g._ "beacon block proposal")
|
||||
|
||||
There is also a companion metric `vouch_client_operation_requests_total`, which is a simple count of the number of operations that have taken place. It has three labels:
|
||||
|
||||
- `proposer` is the endpoint for the operation
|
||||
- `operation` is the operation that took place (_e.g._ "beacon block proposal")
|
||||
- `result` is the result of the operation, either "succeeded" or "failed"
|
||||
|
||||
## Network
|
||||
Network metrics provide information about the network from vouch's point of view. Although these are not under vouch's control, they have an impact on the performance of the validator. The specific metrics are:
|
||||
|
||||
- `vouch_block_receipt_delay_seconds` the delay between the start of a slot and the arrival of the block for that slot. This metric is provided as a histogram, with buckets in increments of 0.1 seconds up to 4 seconds.
|
||||
- `vouch_attestationaggregation_coverage_ratio` the ratio of the number of attestations included in the aggregate to the total number of attestations for the aggregate. This metric is provided as a histogram, with buckets in increments of 0.1 up to 1.
