gotjosh	465891cc56	Rules: Refactor concurrency controller interface (#14491 ) * Rules: Refactor concurrency controller interface Even though the main purpose of this refactor is to modify the interface of the concurrency controller to accept a Context. I did two drive-by modifications that I think are sensible: 1. I have moved the check for dependencies on rules to the controller itself - this aligns with how the controller should behave as it is a deciding factor on wether we should run concurrently or not. 2. I cleaned up some unused methods from the days of the old interface before #13527 changed it.

gotjosh	c10186eeea	BUGFIX: Mark the rule's restoration process as completed always (#14048 ) * BUGFIX: Mark the rule's restoration process as completed always In https://github.com/prometheus/prometheus/pull/13980 I introduced a change to reduce the number of queries executed when we restore alert statuses. With this, the querying semantics changed as we now need to go through all series before we enter the alert restoration loop and I missed the fact that exiting early when there are no rules to restore would lead to an incomplete restoration. An alert being restored is used as a proxy for "we're now ready to write `ALERTS/ALERTS_FOR_SERIES` metrics" so as a result we weren't writing the series if we didn't restore anything the first time around. --------- Signed-off-by: gotjosh <josue.abreu@gmail.com>	7 months ago

gotjosh	4daaa59c08	Rule Manager: Only query once per alert rule when restoring alert state Prometheus restores alert state between restarts and updates. For each rule, it looks at the alerts that are meant to be active and then queries the `ALERTS_FOR_STATE` series for _each_ alert within the rules. If the alert rule has 120 instances (or series) it'll execute the same query with slightly different labels. This PR changes the approach so that we only query once per alert rule and then match the corresponding alert that we're about to restore against the series-set. While the approach might use a bit more memory at start-up (if even?) the restore proccess is only ran once per restart so I'd consider this a big win.

gotjosh	e7219e3d36	Rule Manager: Add `rule_group_last_restore_duration_seconds` to measure restore time per rule group When a rule group changes or prometheus is restarted we need to ensure we restore the active alerts that were firing for a corresponding rule, for that Prometheus uses the `ALERTS_FOR_STATE` series to query the previous state and restore it. If a given rule has high cardinality (think 100s of 1000s for series) this proccess can take a bit of time - this is the first of a series of PRs to improve this problem and I'd like to start with exposing the time it takes to restore a rule group as a gauge.
