You can build simple Icinga 2 setups where everything is checked and notified 24×7. If you are planning with bigger setups and multiple user groups being notified on problems, you’ll certainly get the task to filter specific time ranges or notification types. Or you’ll consider partial check times e.g. when a service is definitely not available and you don’t want your SLA reporting faked with downtimes.
One common thing is to limit the notifications sent to users to “9 to 5”. The configuration requires the following addition:
- TimePeriod object named “9to5” (available in the example configuration in timeperiods.conf)
- Referenced as “period” attribute in your Notification object or apply rule
Human beings don’t work 5 days a week and 52 weeks over the whole year. Vacation is needed, finding some rest without any work. And you obviously don’t want to get notified about Icinga problems during that period of time. In addition to that there are several days or hours where no-one wants to get notified except for the 24×7 support (new year’s eve, christmas, etc.).
