Yuri Tseretyan	f6a46744a6	Alerting: Support hysteresis command expression (#75189) ... 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 --------- Co-authored-by: Sonia Aguilar <soniaaguilarpeiron@gmail.com>	1 year ago

Yuri Tseretyan	938e26b59f	Alerting: Add new metrics and tracings to state manager and scheduler (#71398) ... * add metrics and tracing to state manager * propagate tracer to state manager * add scheduler metrics * fix backtesting * add test for state metrics * remove StateUpdateCount * update docs * metrics can be null * add tracer to new tests	2 years ago
Yuri Tseretyan	cbbbe2e6f6	SSE: DSNode to update result with names to make each value identifiable by labels (only Graphite and TestData) (#71246) ... * introduce a function checkIfSeriesNeedToBeFixed to scan all value fields in the response and provide a function that updates Series so they can be uniquely identifiable. Only Graphite and TestData are checked. * update `convertDataFramesToResults` to run this function and provide it to WideToMany * update WideToMany to run the fix function if it is not nil	2 years ago
Yuri Tseretyan	30fc075cd7	Alerting: Fix panic in backtesting API when the testing interval is not times of evaluation interval (#68727) ... * add test for the bug * update backtesting evaluators to accept a number of evaluations instead of `to` to have control over the number evaluations in one place	2 years ago
George Robinson	7edbe72483	Alerting: Support concurrent queries for saving alert instances (#70525) ... This commit adds support for concurrent queries when saving alert instances to the database. This is an experimental feature in response to some customers experiencing delays between rule evaluation and sending alerts to Alertmanager, resulting in flapping. It is disabled by default.	2 years ago
