Downtimes

Using the known Syncer Rules and the Hosts Attributes, you can create Flexible Downtimes, which can be manged in your CMDB, but then created in Checkmk by the CMDB Syncer.

How to configure

Modules → Checkmk → Manage Downtimes

Start Day	Select the Day for the Downtime in the List
Start Day Template	Set the day, by Jinja Template. English, short mon, tue, wed, thu, fri, sat, sun

Timezones

Downtimes in Checkmk need to be Timezone aware. The Downtimes you enter the gui, will have the Timezone of the Server/ Docker Container where you installed the syncer. But for the Downtime used in Checkmk, you need to overwrite maybe with the local_config.py.

Example local_config.py:

import datetime
config = {
    'TIMEZONE': datetime.timezone.utc,
}
