Version used (icinga2 --version): r2.13.6-1
Operating System and version: CentOS 7.9.2009
Enabled features (icinga2 feature list): api checker ido-mysql influxdb mainlog notification
Icinga Web 2 version and modules (System - About): 2.11.3
Config validation (icinga2 daemon -C): completes without errors.
If you run multiple Icinga 2 instances, the zones.conf file (or icinga2 object list --type Endpoint and icinga2 object list --type Zone) from all affected nodes.: HA Master + Agents (Details can not be shared publicly)

Additional context

Maybe helpful: max_check_attempt is set to 1 for this check.

If you run multiple Icinga 2 instances, the zones.conf file (or icinga2 object list --type Endpoint and icinga2 object list --type Zone) from all affected nodes.: HA Master + Agents (Details can not be shared publicly)

Can you please share at least some more details on the structure, in particular:

Are the agents connected directly to the masters?
Is the check executed using command_endpoint?

mschroeder21 commented 1 year ago

Yes, the agents are directly connected to the masters. We don't have any satellites in this enviroment. Yes, the check is executed using command_endpoint

Any news or ideas what's happening here?

0xliam commented 1 year ago

This might be unrelated to this issue, but we are seeing issues with notifications being sent when a host should be in downtime after a config change is made. If a host or service problem is acknowledged, or put into scheduled downtime, and then a configuration change is made via Icinga Director, those acks and downtimes are purged - this occurs regardless of what zone the Director change is made in.

e.g. I ack a host problem in for host-a in zone-a, create a scheduled downtime for host-b in zone-b, and then push a Director config change for host-c in zone-c - the ack's for host-a and downtime for host-b are removed, but are in the history.

Additionally, when the Icinga master reloads config after a Director deployment, we are seeing a race condition that causes hosts to send down notifications, and a few minutes later, enter downtime:

Is there a possibility to get feedback on this topic?

julianbrost commented 1 year ago

My first guess would be that there could be some inconsistency between both masters. While inside the downtime, you can request https://localhost:5665/v1/objects/services/affected-host-name!affected-service-name from both masters and compare what you get. downtime_depth would be of particular interest as this shows if both masters agree on whether the service is in a downtime.

mschroeder21 commented 1 year ago

Thanks for your answer. Both masters are in sync (downtime_depth is 1 if a service is in downtime). I have also already cleaned /var/lib/icinga2/api/zones/ several times on the second master to get a fresh sync from the config master.

log1-c commented 2 months ago

Something like what @0xliam describes happens in our setup from time to time as well.

The config deployment by the Director was triggered at 18:00 At 18:01:45 configs were synced between the masters (with the config master ignoring the updates from the secondary master) and into the zones. That all was finished at 18:02:10 Between 18:02:10 and 18:02:40 multiple downtimes where created and those successfully suppressed notifications. At 18:02:41 a whole lot of "Syncing configuration files for xyz to " messages (re)appear in the log without a config deployment being triggered, only for the masters The downtime from the screenshot was entered at 18:02:43

Log line for the host that was notified during the supposed downtime
