Monitor Prysm for expected behavior

Expected behavior: Beacon node

When running a beacon node for the first time from a checktpoint, the beacon node will first sync the chain up to the head.

Logs should look like:

...
INFO initial-sync: Waiting for enough suitable peers before syncing required=3 suitable=1
INFO initial-sync: Processing block batch of size 19 starting from 0xf0f0eef4... 7379745/7379882 - estimated time remaining 2m24s blocksPerSecond=0.9 peers=8

...
INFO initial-sync: Synced to head of chain currentSlot=7379887 syncedSlot=7379887
INFO initial-sync: Synced up to slot 7379887

Then, every 12 seconds, you should see these two lines:

INFO blockchain: Synced new block block=0xef79fc34... epoch=230621 finalizedEpoch=230619 finalizedRoot=0xa3861dc4... slot=7379898
INFO blockchain: Finished applying state transition attestations=128 payloadHash=0x3d04fb83067c slot=7379898 syncBitsCount=390 txCount=280

From time to time you'll also see this kind of log:

 INFO p2p: Peer summary activePeers=70 inbound=59 outbound=7

Expected behavior: Validator client

Validators are generally in one of the following states: Unknown, Deposited, Pending, Active, Exiting, Slashing, or Exited. To learn more about these states, visit Validator Lifecycle.

When your validator is in Deposited state, it will produce INFO logs that look like this:

INFO validator: Deposit processed, entering activation queue after finalization... 

When your validator is Pending activation, it will produce INFO logs that look like this:

INFO validator: Waiting to be assigned activation epoch

A healthy Active validator client will produce INFO logs that look like this:

INFO validator: Previous epoch aggregated voting summary attestationInclusionPct=100% averageInactivityScore=0 correctlyVotedHeadPct=100% correctlyVotedSourcePct=100% correctlyVotedTargetPct=100% epoch=255839
