README.md
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
Slack/Discord 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.
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 failederr
: exact sanity failure message
Sanity failure push notification
To receive a Slack, Discord and/or Telgram notification on sanity failure,
define environment variables before running solana-watchtower
:
export SLACK_WEBHOOK=...
export DISCORD_WEBHOOK=...
Telgram requires the following two variables:
export TELEGRAM_BOT_TOKEN=...
export TELEGRAM_CHAT_ID=...
