How to make icinga plan a active check every night?

Question

I have a test to make on a server which takes some time. I would like the test to get planned every nights between 3h and 5h AM.

In addition user may launch the test during the day.

Is it possible with Icinga2?

Answer 1

This should be possible...

1.Create a TimePeriod, e.g. in timeperiods.conf

object TimePeriod "3to5" {  
   display_name = "Icinga 2 3to5 TimePeriod"  
   ranges = {  
    "monday"    = "03:00-5:00"  
    "tuesday"   = "03:00-5:00"   
    "wednesday" = "03:00-5:00"  
    "thursday"  = "03:00-5:00"  
    "friday"    = "03:00-5:00"
   }  
 }  

2.apply Service

apply Service "some_action" {  
    import "some_check"  
    max_check_attempts = 1  
    check_period = "3to5"  
    ...  
}

3.to manually execute this service just klick the "check now" button in the web interface

BUT ... the people from monitoring-portal advice against it: https://monitoring-portal.org/woltlab/index.php?thread/41080-schedule-check-on-a-specific-time/ : We can read

Executing a check at a specific time won't really work with Icinga 2 and interval based scheduling. Better create a cronjob for it, and feed the check result into the REST API*.
