lpugoy	c792af3ad0	grafana-mixin: Fix expression for GrafanaRequestsFailing alert (#63382) ... Fix expression for GrafanaRequestsFailing alert The intent of the alert is to get the ratio of 5xx to all status codes [^1]. With the original expression, the left hand side can have more than one row with the same labels except for the status code. This results in a promql error because it is doing a many-to-one matching. Doing a sum on the left hand side first should preserve the intent of the alert and resolve the issue. [^1]: https://github.com/grafana/grafana/pull/43116	2023-05-04 14:35:36 +02:00
Carlos Juan Gómez Peñalver	984e293d60	many-to-one requires explicit grouping (#58174) ... The current query results in a many-to-one relationship which requires explicit grouping see more details here https://github.com/portefaix/portefaix-hub/pull/306 https://prometheus.io/docs/prometheus/latest/querying/operators/#many-to-one-and-one-to-many-vector-matches	2023-02-21 11:00:48 +01:00
Pedro Araújo	18fdb89554	grafana-mixin: Fix GrafanaRequestsFailing alert (#43116) ... Due to PromQL's label matching, both sides of the division will have same series; that means that, whenever there's a 5xx error, both sides will have the same value and the division will be `1`. I believe the idea was to get the ratio of 5xx compared will all status code, and to do that, we need to aggregate the `status_code` dimension away.	2021-12-20 15:12:37 +01:00
