Alertmanager: how to send alerts only in weekdays?

Question

I tried to add this to my alertmanager.yml in root level, but I got this error: yaml: unmarshall errors: field time_intervals not found in type config.plain

time_intervals:
  - times:
    weekdays: ['monday:friday']

(I used 0.23 version of Alertmanager)

Answer 1

The correct syntax is the following:

time_intervals:
  - name: monday-to-friday
    time_intervals:
      - weekdays: ['monday:friday']

You can use this time interval like shown in the following example:

route:
  group_by: ...
  ...
  routes:
    - receiver: SOME-RECEIVER
      matchers:
        - SOME-MATCHER
      active_time_intervals:
        - monday-to-friday
    ...
