Renamed Metrics

The table below contains all metrics renamed in v3.0.0 (@johnstonematt):

Old Name	New Name
solana_validator_activated_stake	solana_validator_active_stake
solana_confirmed_transactions_total	solana_node_transactions_total
solana_confirmed_slot_height	solana_node_slot_height
solana_confirmed_epoch_number	solana_node_epoch_number
solana_confirmed_epoch_first_slot	solana_node_epoch_first_slot

solana_leader_slots_total	solana_validator_leader_slots_total
solana_leader_slots_by_epoch	solana_validator_leader_slots_by_epoch_total
solana_active_validators	solana_cluster_validator_count

Metrics were renamed to:

• Remove commitment levels from metric names.
• Standardise naming conventions:
  • solana_validator_*: Validator-specific metrics which are trackable from any RPC node (i.e., active stake).
  • solana_node_*: Node-specific metrics which are not trackable from other nodes (i.e., node health).

Label Updates

The following labels were renamed (@johnstonematt):

• pubkey was renamed to votekey, to clearly identity that it refers to the address of a validators vote account.

• -nodekey
• -comprehensive-slot-tracking
• -monitor-block-sizes
• -slot-pace
• -light-mode
• -http-timeout
• -comprehensive-vote-account-tracking
• -active-identity
• epoch-cleanup-time
