The `solana-watchtower` program is used to monitor the health of a cluster. It
|
|
periodically polls the cluster over an RPC API to confirm that the transaction
|
|
count is advancing, new blockhashes are available, and no validators are
|
|
delinquent. Results are reported as InfluxDB metrics, with an optional push
|
|
notification on sanity failure.
|
|
|
|
If you only care about the health of one specific validator, the
|
|
`--validator-identity` command-line argument can be used to restrict failure
|
|
notifications to issues only affecting that validator.
|
|
|
|
If you do not want duplicate notifications, for example if you have elected to
|
|
receive notifications by SMS the
|
|
`--no-duplicate-notifications` command-line argument will suppress identical
|
|
failure notifications.
|
|
|
|
### Metrics
|
|
#### `watchtower-sanity`
|
|
On every iteration this data point will be emitted indicating the overall result
|
|
using a boolean `ok` field.
|
|
|
|
#### `watchtower-sanity-failure`
|
|
On failure this data point contains details about the specific test that failed via
|
|
the following fields:
|
|
* `test`: name of the sanity test that failed
|
|
* `err`: exact sanity failure message
