Alertmanager: resolved message received immediately after warning message even resolve_timeout is 5m

[leiwa...@gmail.com]

rules.yml

groups:

- name: network-delay

  rules:

  - alert: "network delay"

    expr: probe_duration_seconds * 1000 > 3000

    for: 1s

    labels:

      severity: warning

      team: ops

    annotations:

      description: "{{$labels.instance}} : {{ $value }}"

alertmanager resolve_timeout is 5m

So after a warning is fired, in my opinion at least 5 mins later the resolved messge can be sent. But the resolved msg is sent immediately after the warning msg. why?

Thanks,

resolve_timeout is only relevant in very rare cases, at least when
Alertmanager is used together with Prometheus.

What's your reason for asking? Are you maybe looking for group_wait and
group_interval instead?

Kind regards,

Yes，my AlertManager is used together with Prometheus. 

In prometheus.yml: 

alerting:

  alertmanagers:

  - static_configs:

    - targets: ["x.x.x.x:9093"]

For all the warning message i received,  then immediately  a resolved message received.  This is not i want. 

Thanks,
