There's a cool guide about Solana node monitoring describes how one could setup monitoring using Telegraf + InfluxDb + Grafana.
All instruments could be wrapped into docker containers. I'll show only how to spin-up Telegraf instance.
Prerequisites:
Docker
sudo apt install docker.io curl -y && \ sudo systemctl enable docker && \ sudo systemctl start docker
Telegraf config
If you plan to send metrics to Solana community dashboard then use this config, if you create your own environment (influxDb + grafana) then you might use same config but with substituted values in [[outputs.influxdb]] section.
In both cases we update [[inputs.exec]] section with new commands
[[inputs.exec]]
commands = ["/root/solanamonitoring/monitor.sh -s /bin/bash root"]
save telegraf config on server using path: /home/user/telegraf/telegraf.conf
Monitoring shell script
Could be taken from here (don't forget to update values accordingly)
identityPubkey="your pubkey"
voteAccount="your voteaccount"
rpcURL="http://127.0.0.1:8899"
save monitor.sh on server using path: /home/user/solanamonitoring/monitor.sh
Docker command
sudo docker run -d
--network="host"
--name=telegraf
--restart=always
-v /home/user/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf
-v /home/user/solana/solanamonitoring:/home/user/solana/solanamonitoring
-v /home/user/.config/solana:/home/user/.config/solana
-v /home/user/.local/share/solana:/home/user/.local/share/solana
-v /:/hostfs:ro
-v /etc:/hostfs/etc:ro
-v /proc:/hostfs/proc:ro
-v /sys:/hostfs/sys:ro
-v /var/run/utmp:/var/run/utmp:ro
-e HOST_ETC=/hostfs/etc
-e HOST_PROC=/hostfs/proc
-e HOST_SYS=/hostfs/sys
-e HOST_MOUNT_PREFIX=/hostfs
telegraf:latest
Configure telegraf container
Monitor.sh has jq and bc dependancies, we need to install them inside of docker container, therefore
- connect to container sudo docker exec -it telegraf bash
- run command apt-get update && apt-get install jq && apt-get install bc
- check that solana is connected to the right cluster (devnet, testnet, mainnet) /home/user/.local/share/solana/install/active_release/bin/solana config get
to connect to testnet cluster, use /home/user/.local/share/solana/install/active_release/bin/solana config set --url http://api.testnet.solana.com
- exit
- check that telegraf logs are Ok sudo docker logs telegraf -f --tail 20
Done
