Yuri Tseretyan	810fbc3327	SSE: Support hysteresis threshold expression (#70998) ... * extend threshold command with second evaluator called `unloadEvaluator` * Introduce a new expression command Hysteresis and update Threshold unmarshaller to create the HysteresisCommand if the second eval * add feature flag `recoveryThreshold` * update unmarshal threshold command to not re-marshall because it breaks frame definition by shuffling the schema and data fields	2 years ago

Kyle Brandt	35e488b22b	SSE: Localize/Contain Errors within an Expression (#73163) ... Changes SSE to not always fail all queries when one fails. Now only the query itself, and nodes that depend on it will error. --------- Co-authored-by: Gilles De Mey <gilles.de.mey@gmail.com>	2 years ago

Kyle Brandt	e78be44e1a	SSE: Dataplane Compliance (#65927) ... Takes a specific code path for data that identifies itself as dataplane instead of "guessing" what the data is. The data must identify itself by being in the dataplane by having both the following frame metadata properties: - TypeVersion property that is greater than 0.0 - 'Type' property The flag is disableSSEDataplane and disables this functionality and uses the old code for all queries regardless. See https://github.com/grafana/grafana-plugin-sdk-go/blob/main/data/contract_docs/contract.md for dataplane details.	2 years ago

Kyle Brandt	05fd7eb047	SSE: Add noData type (#51973) ... When there is a single frame with no fields (e.g. splunk datasource) SSE errors when trying to figure out the data type. This frame needs to exist since this is where the executedQueryString metadata exists. This adds a new return type to SSE to represent no data, so the original frame with its metadata can still be maintained.	3 years ago

Jean-Philippe Quéméner	2319c52c85	Alerting: fix a bug where the metric in the evaluation string was not correctly populated (#41731) ... Instead of using the frame name as the series name, we now use the name of the series value column if the frame name is not set. Queries to some datasources may end up with an empty frame name, which leads to an empty series name. As the series name is used in the frontend to display which metrics were queried etc. it shouldn't be empty.	4 years ago
