Unable to use regex for ints in alert policy creation

[fflorez]

I have been following #299 and I know it was closed last week. I am still facing issues with regex in promql for integers in alert policies. The query is working in metrics explorer and I can also get data in the alert policy but when I try to create the alert policy its failing

PROMQL query: (sum by ("destination_canonical_service_name", "destination_canonical_service_namespace") (sum_over_time({"__name__"="istio_io:service_server_request_count","monitored_resource"="k8s_container", "response_code"=~"5..", "project_id"=~"sdg-sds-prod"}[5m])) /sum by ("destination_canonical_service_name", "destination_canonical_service_namespace") (sum_over_time({"__name__"="istio_io:service_server_request_count","monitored_resource"="k8s_container", "project_id"=~"sdg-sds-prod"}[5m]))) AND (sum by ("destination_canonical_service_name", "destination_canonical_service_namespace") (sum_over_time({"__name__"="istio_io:service_server_request_count","monitored_resource"="k8s_container", "project_id"=~"sdg-sds-prod"}[30m])) / (5*60) > 5) > 0.10

Error Message: unable to parse value in matcher on int label to an int: strconv.ParseInt: parsing "5..": invalid syntax

There's a validation step that happens before Alerts are saved. It appears that hasn't been updated for the new regex logic that's allowed.

I'll prioritize that, will get back to you.

Hi @lyanco do you have any update on this issue?

This now seems to be working! The following query works:

histogram_quantile(0.99,sum by ("response_code","le")(increase({"__name__"="istio_io:service_server_response_bytes_bucket","monitored_resource"="k8s_container", response_code=~"5.."}[1m])))
