Prometheus Endpoint

This is the list of the prometheus statistics that are exposed by tenderduty. An example Grafana dashboard is planned, but not ready. Some notes about the stats:

• All metrics are gauges, because counters are reset at startup using counters is ill-advised.
• All endpoints include the following attributes: chain_id, moniker, and name.
• Node specifc stats include an additional attribute: endpoint, which contains the RPC node's URL.

tenderduty_consecutive_missed_blocks

The current count of consecutively missed blocks regardless of precommit or prevote status

tenderduty_consecutive_missed_blocks{chain_id="chain-id",moniker="Moniker",name="Chain Name"} 0

tenderduty_endpoint_down_seconds

How many seconds a node has been marked as unhealthy

tenderduty_endpoint_down_seconds{chain_id="chain-id",endpoint="http://somehost:26657",moniker="Moniker",name="Chain Name"} 0

tenderduty_missed_block_window

The missed block aka slashing window

tenderduty_missed_block_window{chain_id="chain-id",moniker="Moniker",name="Chain Name"} 10000

tenderduty_missed_blocks

Count of blocks missed without seeing a precommit or prevote since tenderduty was started

tenderduty_missed_blocks{chain_id="chain-id",moniker="Moniker",name="Chain Name"} 0

tenderduty_missed_blocks_for_window

The current count of missed blocks in the slashing window regardless of precommit or prevote status

tenderduty_time_since_last_block

How many seconds since the previous block was finalized, only set when a new block is seen, not useful for stall detection, helpful for averaging times

tenderduty_time_since_last_block_unfinalized

How many seconds since the previous block was finalized, set regardless of finalization, useful for stall detection, not helpful for figuring average time

tenderduty_total_monitored_endpoints

The count of rpc endpoints being monitored for a chain

tenderduty_total_monitored_endpoints{chain_id="chain-id",moniker="Moniker",name="Chain Name"} 3

tenderduty_total_unhealthy_endpoints

The count of unhealthy rpc endpoints being monitored for a chain
