Scheduled downtime configuration for Nagios Core

Postby suresh.ramasamy » Thu Mar 16, 2017 8:21 am

After some research in google found the below configuration to be used in timeperiods.cfg for scheduling downtime.

Code: Select all
define timeperiod{
        timeperiod_name weekly-maintenance
        alias           Weekly Maintenance Windows
        sunday          00:00-04:29,04:45-00:00
        monday          00:00-04:29,04:45-00:00
        tuesday         00:00-04:29,04:45-00:00
        wednesday       00:00-04:29,04:45-00:00
        thursday        00:00-04:29,04:45-00:00
        friday          00:00-04:29,04:45-00:00
}


here is the template.cfg configuration.

Code: Select all
define service{
        name                            CRM-Service   ; The 'name' of this service template
        active_checks_enabled           1                       ; Active service checks are enabled
        passive_checks_enabled          1                       ; Passive service checks are enabled/accepted
        parallelize_check               1                       ; Active service checks should be parallelized (disabling this can lead to major performance problems)
        obsess_over_service             1                       ; We should obsess over this service (if necessary)
        check_freshness                 0                       ; Default is to NOT check service 'freshness'
        notifications_enabled           1                       ; Service notifications are enabled
        event_handler_enabled           1                       ; Service event handler is enabled
        flap_detection_enabled          1                       ; Flap detection is enabled
        failure_prediction_enabled      1                       ; Failure prediction is enabled
        process_perf_data               1                       ; Process performance data
        retain_status_information       1                       ; Retain status information across program restarts
        retain_nonstatus_information    1                       ; Retain non-status information across program restarts
        is_volatile                     0                       ; The service is not volatile
        check_period                    24x7                    ; The service can be checked at any time of the day
        max_check_attempts              3                       ; Re-check the service up to 3 times in order to determine its final (hard) state
        normal_check_interval           2                      ; Check the service every 10 minutes under normal conditions
        retry_check_interval            1                       ; Re-check the service every two minutes until a hard state can be determined
        contact_groups                  CRMadmins                     ; Notifications get sent out to everyone in the 'admins' group
        notification_options            w,u,f,c,r                 ; Send notifications about warning, unknown, critical, and recovery events
        notification_interval           5                     ; Re-notify about service problems every hour
        notification_period             weekly-maintenance                   ; Notifications can be sent out at any time
         register                        0                      ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!
        }


Based on the provided timeperiod.cfg configuration, scheduled downtime would be between 4:30 to 4:45 and there should not be any alert sent out during this time frame.

we are not getting alert E-Mails or recovery emails even after completing the scheduled downtime which is 4:30 to 4:45.

is any change required in my current setup ?

You should revise your time period like so:

Code: Select all
define timeperiod{
timeperiod_name weekly-maintenance
alias Weekly Maintenance Windows
sunday 00:00-04:29,04:45-24:00
monday 00:00-04:29,04:45-24:00
tuesday 00:00-04:29,04:45-24:00
wednesday 00:00-04:29,04:45-24:00
thursday 00:00-04:29,04:45-24:00
friday 00:00-04:29,04:45-24:00
}


Your previous range of 04:45-00:00 was incorrect. If you want a range that means "from 04:45 until the end of the day", 04:45-24:00 is more appropriate. This combined with your template should effectively establish a period from 04:29-04:45 in which no notifications are sent for all hosts using that template.

You may also want to include Saturday depending on whether or not maintanance is run on that day.
