Monitoring a Validator

Check Gossip

Confirm the IP address and identity pubkey of your validator is visible in the gossip network by running:

solana-gossip spy --entrypoint devnet.solana.com:8001

Check Your Balance

Your account balance should decrease by the transaction fee amount as your validator submits votes, and increase after serving as the leader. Pass the --lamports are to observe in finer detail:

solana balance --lamports

Check Vote Activity

The solana vote-account command displays the recent voting activity from your validator:

solana vote-account ~/vote-account-keypair.json

Get Cluster Info

There are several useful JSON-RPC endpoints for monitoring your validator on the cluster, as well as the health of the cluster:

# Similar to solana-gossip, you should see your validator in the list of cluster nodes
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getClusterNodes"}' http://devnet.solana.com
# If your validator is properly voting, it should appear in the list of `current` vote accounts. If staked, `stake` should be > 0
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getVoteAccounts"}' http://devnet.solana.com
# Returns the current leader schedule
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getLeaderSchedule"}' http://devnet.solana.com
# Returns info about the current epoch. slotIndex should progress on subsequent calls.
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getEpochInfo"}' http://devnet.solana.com

Validator Metrics

Metrics are available for local monitoring of your validator.

Docker must be installed and the current user added to the docker group. Then download solana-metrics.tar.bz2 from the Github Release and run

tar jxf solana-metrics.tar.bz2
cd solana-metrics/
./start.sh

A local InfluxDB and Grafana instance is now running on your machine. Define SOLANA_METRICS_CONFIG in your environment as described at the end of the start.sh output and restart your validator.

Metrics should now be streaming and visible from your local Grafana dashboard.

Timezone For Log Messages

Log messages emitted by your validator include a timestamp. When sharing logs with others to help triage issues, that timestamp can cause confusion as it does not contain timezone information.

To make it easier to compare logs between different sources we request that everybody use Pacific Time on their validator nodes. In Linux this can be accomplished by running:

sudo ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
