Fields§

§current_epoch: IntGauge

The current epoch ID. This is updated only when the AuthorityState finishes reconfiguration.

§current_voting_right: IntGauge

Current voting right of the validator in the protocol. Updated at the start of epochs.

§epoch_total_duration: IntGauge

Total duration of the epoch. This is measured from when the current epoch store is opened, until the current epoch store is replaced with the next epoch store.

§epoch_checkpoint_count: IntGauge

Number of checkpoints in the epoch.

§epoch_transaction_count: IntGauge

Number of transactions in the epoch.

§epoch_total_gas_reward: IntGauge

Total amount of gas rewards (i.e. computation gas cost) in the epoch.

§epoch_pending_certs_processed_time_since_epoch_close_ms: IntGauge

The duration from when the epoch is closed (i.e. validator halted) to when all pending certificates are processed (i.e. ready to send EndOfPublish message). This is the duration of (1) through (2) above.

§epoch_end_of_publish_quorum_time_since_epoch_close_ms: IntGauge

The interval from when the epoch is closed to when we receive 2f+1 EndOfPublish messages. This is the duration of (1) through (3) above.

§epoch_last_checkpoint_created_time_since_epoch_close_ms: IntGauge

The interval from when the epoch is closed to when we created the last checkpoint of the epoch. This is the duration of (1) through (4) above.

§epoch_reconfig_start_time_since_epoch_close_ms: IntGauge

The interval from when the epoch is closed to when we finished executing the last transaction of the checkpoint (and hence triggering reconfiguration process). This is the duration of (1) through (5) above.

§epoch_validator_halt_duration_ms: IntGauge

The total duration when this validator is halted, and hence does not accept certs from users. This is the duration of (1) through (6) above, and is the most important latency metric reflecting reconfiguration delay for each validator.

§epoch_first_checkpoint_created_time_since_epoch_begin_ms: IntGauge

The interval from when the epoch begins (i.e. right after state reconfigure, when the new epoch_store is created), to when the first checkpoint of the epoch is ready for creation locally. This is (7) above, and is a good proxy to how long it takes for the validator to become useful in the network after reconfiguration.

§is_safe_mode: IntGauge

Whether we are running in safe mode where reward distribution and tokenomics are disabled.

§checkpoint_builder_advance_epoch_is_safe_mode: IntGauge

When building the last checkpoint of the epoch, we execute advance epoch transaction once without committing results to the store. It’s useful to know whether this execution leads to safe_mode, since in theory the result could be different from checkpoint executor.

§effective_buffer_stake: IntGauge

Buffer stake current in effect for this epoch

§epoch_random_beacon_dkg_failed: IntGauge

Set to 1 if the random beacon DKG protocol failed for the most recent epoch.

§epoch_random_beacon_dkg_num_shares: IntGauge

The number of shares held by this node after the random beacon DKG protocol completed.

§epoch_random_beacon_dkg_epoch_start_completion_time_ms: IntGauge

The amount of time taken from epoch start to completion of random beacon DKG protocol, for the most recent epoch.

§epoch_random_beacon_dkg_completion_time_ms: IntGauge

The amount of time taken to complete random beacon DKG protocol from the time it was started (which may be a bit after the epcoh began), for the most recent epoch.

§epoch_random_beacon_dkg_message_time_ms: IntGauge

The amount of time taken to start first phase of the random beacon DKG protocol, at which point the node has submitted a DKG Message, for the most recent epoch.

§epoch_random_beacon_dkg_confirmation_time_ms: IntGauge

The amount of time taken to complete first phase of the random beacon DKG protocol, at which point the node has submitted a DKG Confirmation, for the most recent epoch.

§epoch_execution_time_observations_shared: IntCounter

The number of execution time observations messages shared by this node.

§epoch_execution_time_observations_sharing_reason: IntCounterVec

The number of execution time observations messages intended to be shared by this node, annotated with reason.

§epoch_execution_time_measurements_dropped: IntCounter

The number of execution time measurements dropped due to backpressure from the observer.

§epoch_execution_time_observations_dropped: IntCounterVec

The number of execution time consensus messages dropped.

§epoch_execution_time_observer_indebted_objects: IntGauge

The number of cached indebted objects in the execution time observer.

§epoch_execution_time_observer_utilization_cache_size: IntGauge

The number of objects tracked by the object utilization cache.

§epoch_execution_time_observer_overutilized_objects: IntGauge

The number of objects determined by the execution time observer to be overutilized. Note: this may overcount if objects are evicted from the cache before being computed as not-overutilized.

§epoch_execution_time_observer_object_utilization: CounterVec

Per-object utilization for objects that were overutilized at least once at some point in their lifetime. Note: This metric is disabled by default as it may have very large cardinality.

§epoch_execution_time_observations_loaded: IntGauge

The number of execution time observations loaded at start of epoch.

§consensus_quarantine_queue_size: IntGauge

The number of consensus output items in the quarantine.

§shared_object_assignments_size: IntGauge

The number of shared object assignments in the quarantine.
