Prometheus alert not peding/firing at second time -


i have simple prometheus alert configured

alert myservicedown   if my_custom_metric == 0   15s

scenario follows:

  1. in correct runtime my_custom_metric 1, , myservicedown alert green @ alert tab.
  2. then set my_custom_metric 0 , propetheus retrieves 0, can see @ graph -> console tab.
  3. myservicedown becomes pending (yellow) , after 15 seconds becomes firing (red).
  4. then "fix bug", my_custom_metric 1 again, , myservicedown alert green.

here comes strange part. break app second time my_custom_metric 0 again. shown @ graph -> console. myservicedown alert never pending or firing. when restart prometheus works good, once.

what doing wrong?

there bug in version 0.17rc1

https://github.com/prometheus/prometheus/issues/1372

it fixed in 0.17rc2

problem solved.
