* whoops
* Require no error in responding
* fix linter
* Panic, no need to pass testing around
* Extend status test
* Simple replace of State.Resolved with State.ResolvedAt
* Retain ResolvedAt time between Normal->Normal transition
* Introduce ResolvedRetention to keep sending recently resolved alerts
* Make ResolvedRetention configurable with resolved_alert_retention
* Tick-based LastSentAt for testing of ResendDelay and ResolvedRetention
* Do not reset ResolvedAt during Normal->Pending transition
Initially this was done to be inline with Prom ruler. However, Prom ruler
doesn't keep track of Inactive->Pending/Alerting using the same alert instance,
so it's more understandable that they choose not to retain ResolvedAt. In our
case, since we use the same cached instance to represent the transition, it
makes more sense to retain it.
This should help alleviate some odd situations where temporarily entering
Pending will stop future resolved notifications that would have happened
because of ResolvedRetention.
* Pointers for ResolvedAt & LastSentAt
To avoid awkward time.Time{}.Unix() defaults on persist
* Make MakeDependencyError public for tests in another package
* Create tests for errors in eval results
* Extract logic to pull frame errors out into exported function
* Maybe we can drop cyclomatic complexity lint suppression now?
* extract frame errors and fail recording rules if frames contain error
* Fix up retry logic to actually work
* Do not retry non retryable errors
* Basic eval flow
* Wiring-up
* fix
* Extend todo
* Start with tests
* Include some relevant tests, skip ones that seem to have timing-based race conditions
* Some tests, touch up linter and todo
* Solve TODO
* Add tracing
* Tests to make sure an eval went through
* Wire up feature toggles
* Update pkg/services/ngalert/schedule/recording_rule.go

* create rule factory for more complicated dep injection into rules
* Rules get direct access to metrics, logs, traces utilities, use factory in tests
* Use clock internal to rule
* Use sender, statemanager, evalfactory directly
* evalApplied and stopApplied
* use schedulableAlertRules behind interface
* loaded metrics reader
* 3 relevant config options
* Drop unused scheduler parameter
* Rename ruleRoutine to run
* Update READMED
* Handle long parameter lists
* remove dead branch
* Add notification settings to storage\domain and API models. Settings are a slice to workaround XORM mapping
* Support validation of notification settings when rules are updated
* Implement route generator for Alertmanager configuration. That fetches all notification settings.
* Update multi-tenant Alertmanager to run the generator before applying the configuration.
* Add notification settings labels to state calculation
* update the Multi-tenant Alertmanager to provide validation for notification settings
* update GET API so only admins can see auto-gen
* Alerting: fix race condition in (*ngalert/sender.ExternalAlertmanager).Run
* Chore: Fix data races when accessing members of *ngalert/state.FakeInstanceStore
* Chore: Fix data races in tests in ngalert/schedule and enable some parallel tests
* Chore: fix linters
* Chore: add TODO comment to remove loopvar once we move to Go 1.22
* Simple, per-base-interval jitter
* Add log just for test purposes
* Add strategy approach, allow choosing between group or rule
* Add flag to jitter rules
* Add second toggle for jittering within a group
* Wire up toggles to strategy
* Slightly improve comment ordering
* Add tests for offset generation
* Rename JitterStrategyFrom
* Improve debug log message
* Use grafana SDK labels rather than prometheus labels
Backend:
* Update the Grafana Alerting engine to provide feedback to HysteresisCommand. The feedback information is stored in state.Manager as a fingerprint of each state. The fingerprint is persisted to the database. Only fingerprints that belong to Pending and Alerting states are considered as "loaded" and provided back to the command.
- add ResultFingerprint to state.State. It's different from other fingerprints we store in the state because it is calculated from the result labels.
- add rule_fingerprint column to alert_instance
- update alerting evaluator to accept AlertingResultsReader via context, and update scheduler to provide it.
- add AlertingResultsFromRuleState that implements the new interface in eval package
- update getExprRequest to patch the hysteresis command.
* Only one "Recovery Threshold" query is allowed to be used in the alert rule and it must be the Condition.
Frontend:
* Add hysteresis option to Threshold in UI. It's called "Recovery Threshold"
* Add test for getUnloadEvaluatorTypeFromCondition
* Hide hysteresis in panel expressions
* Refactor isInvalid and add test for it
* Remove unnecesary React.memo
* Add tests for updateEvaluatorConditions
