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
