Kyle Brandt	63b2dd06a5	Alerting: Set "value" with evalmatches in G Managed (#34075) ... When, and currently only when using a classic condition, evaluation information is added (which is like the EvalMatches from dashboard alerting). This is returned via the API and can be included in notifications by reading the `__value__` label attached `.Alerts` in the template. It is a string.	4 years ago

Kyle Brandt	05fa9d6ad9	AlertingNG: rename Condition properties to match front end (#32267)	4 years ago
Kyle Brandt	7bb79158ed	SSE/Alerting: First pass at query/condition translation (#31693) ... - Takes the conditions property from the settings column of an alert from alerts table and turns into an ng alerting condition with the queries and classic condition. - Has temp API rest endpoint that will take the dashboard conditions json, translate it to SEE queries + classic condition, and execute it (only enabled in dev mode). - Changes expressions to catch query responses with a non-nil error property - Adds two new states for an NG instance result (NoData, Error) and updates evaluation to match those states - Changes the AsDataFrame (for frontend) from Bool to string to represent additional states - Fix bug in condition model to accept first Operator as empty string. - In ngalert, adds GetQueryDataRequest, which was part of execute and is still called from there. But this allows me to get the Expression request from a condition to make the "pipeline" can be built. - Update AsDataFrame for evalresult to be row based so it displays a little better for now	4 years ago
