|---|---|---|---|
active-restoring-tasks | count | The number of active tasks currently undergoing restoration | |
standby-updating-tasks | count | The number of active tasks currently undergoing updating | |
active-paused-tasks | count | The number of active tasks paused restoring | |
standby-paused-tasks | count | The number of standby tasks paused updating | |
idle-ratio | gauge (percentage) | The fraction of time the thread spent on being idle | idle-ratio + restore-ratio + checkpoint-ratio should be 1 |
restore-ratio | gauge (percentage) | The fraction of time the thread spent on restoring active or standby tasks | idle-ratio + restore-ratio + checkpoint-ratio should be 1 |
checkpoint-ratio | gauge (percentage) | The fraction of time the thread spent on checkpointing restored progress | idle-ratio + restore-ratio + checkpoint-ratio should be 1 |
active-records-restored-total | count | The total number of records restored for active tasks | it is for the lifetime of the streams app, hence ever going |
standby-records-updated-total | count | The total number of records updated for active tasks | it is for the lifetime of the streams app, hence ever going |
active-records-remaining | count | The number of records remained to be restored | it should be usually declining, and during rebalance it may be jumping up or down |
standby-records-remaining | count | The number of records remained to be updated | it could be usually increasing or declining, and during rebalance it may be jumping up or down |
records-restored-rate | rate | The average per-second number of records restored for active or updated for standby | it counts for both active and standby tasks; but at any given time it should be either restoring active or updating standby or being idle |
restore-call-rate | rate | The average per-second number of restore calls triggered |
