zenador	69edd8709b	Add warnings (and annotations) to PromQL query results (#12152 ) Return annotations (warnings and infos) from PromQL queries This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations". Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future. The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms). The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later. Another TODO is to take annotations into account when evaluating recording rules. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	2 years ago
Gregor Zeitlinger	f01718262a	Unit tests for native histograms (#12668 ) promql: Extend testing framework to support native histograms This includes both the internal testing framework as well as the rules unit test feature of promtool. This also adds a bunch of basic tests. Many of the code level tests can now be converted to tests within the framework, and more tests can be added easily. --------- Signed-off-by: Harold Dost <h.dost@criteo.com> Signed-off-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com> Signed-off-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Harold Dost <h.dost@criteo.com> Co-authored-by: Stephen Lang <stephen.lang@grafana.com> Co-authored-by: Gregor Zeitlinger <gregor.zeitlinger@grafana.com>	2 years ago

Filip Petkovski	97c7fffbb8	parser: Allow parsing arbitrary functions In Thanos we would like to start experimenting with custom functions that are currently not part of the PromQL spec. We would do this by adding an implementation for those functions in the Thanos engine: https://github.com/thanos-community/promql-engine and allow users to decide which engine they want to use on a per-query basis. Since we use the PromQL parser from Prometheus, injecting functions in the global `Functions` variable would mean they also become available for the Prometheus engine. To avoid this side-effect, this commit exposes a Parser interface in which the supported functions can be injected as an option. If not functions are injected, the parser implementation will default to the functions defined in the global Functions variable. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	3 years ago

Tobias Guggenmos	f5eed7ae0a	PromQL: Fix panic in parser (#6650 ) Fixes #6649. The crash is fixed here, was caused because some AST sanity checks were performed on the syntax tree while assembling it. In case of previous parsing errors this could lead to undefined behaviour. The fix is to move the checks to the typechecking phase, which runs only when a syntax tree was assembled without there being parsing errors. There are other places, where similiar checks are performed while assembling the syntax tree. It might be a good idea to move those to the typechecking phase, too. Should I do this in the same or a separate PR? Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>	6 years ago
