In this section we will tell you how to Monitor a Validator using Nexis CLI

​
Prerequisites

Command Line Interface

Nexis CLI should be installed

​
Check Gossip

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

​
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: 
nexis balance --lamports

​
Check Vote Activity

The nexis vote-account command displays the recent voting activity from your validator: 
nexis 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 nexis-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://api.devnet.nexis.network:8899
# 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://api.devnet.nexis.network:8899
# Returns the current leader schedule
curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"getLeaderSchedule"}' http://api.devnet.nexis.network:8899
# 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://api.devnet.nexis.network:8899
