Multiple timeperiods/retry intervals for a host/service?

Hi All,
I've been tasked to see if I can configure our NagiosXI instance to have a different check_interval or retry interval based on the time of day.
Essentially during business hours they want everything to be the standard 5 minute check, 1 min retry, 1 max check attempt handling of checks/notifications,
but after hours they do not want any alert sent until a service has failed for at least 15 minutes.
I can't see a simple way to accomplish this and was hoping someone out there might have tried something like this before.
Thanks for any help/suggestions

The only way I can see this being accomplished is to set up two separate checks. One could be using the "workhours" timeperiod, the other one - a custom ("off-work" hours) timeperiod. During normal business hours, you could be checking the service every 5 min. During "off-work" hours, you could be checking this service less frequently, i.e. every 15 min. Here's an example:
Code: Select all
define service {
host_name localhost
service_description Current Users - business hours
use local-service
check_command check_local_users!2!5!!!!!!
max_check_attempts 1
check_interval 5
retry_interval 1
check_period workhours
register 1
}
define service {
host_name localhost
service_description Current Users - offwork hours
use local-service
check_command check_local_users!2!5!!!!!!
max_check_attempts 1
check_interval 15
retry_interval 1
check_period offworkhours
register 1
}
define timeperiod {
timeperiod_name workhours
alias Normal Work Hours
monday 09:00-17:00
tuesday 09:00-17:00
wednesday 09:00-17:00
thursday 09:00-17:00
friday 09:00-17:00
}
define timeperiod {
timeperiod_name offworkhours
alias Off Work Hours
saturday 00:00-24:00
monday 00:00-08:59,17:01-23:59
tuesday 00:00-08:59,17:01-23:59
wednesday 00:00-08:59,17:01-23:59
thursday 00:00-08:59,17:01-23:59
friday 00:00-08:59,17:01-23:59
sunday 00:00-24:00
}
Hope this helps.

Built in, this isn't going to be possible. The only ways to really accomplish this that I could see are going to be -
1. Two different XI servers, running the same configuration, with the different options selected.
2. Two services setup for every single one.
3. Having one 'master template' that applies to all your services, that you change each day.

I imagine this could be done w/ a bit of scripting and the new API, but an old time and blindingly simple way would be to define a pair of host template files w/ different values.
Have cron copy one into /usr/local/nagios/etc/import/ at the right time, then run the reconfig script from the right dir. Then at the right time another similar cron job copies the other to import and reconfigures.
Do the same w/ a pair of service templates.
This should take an hour or so to set up.
The reconfig imports the values, updates the templates, and applies the changes.
Of course, you need to update all your hosts and services to use templates, but that too can be done via an import, and probably better via the API.
Examples templates
Code: Select all
define host {
name base_host
alias Template containing notification and check intervals. Used by templates
check_command check_ping!3000.0,80%!5000.0,100%!!!!!!
max_check_attempts 4
check_interval 5
retry_interval 1
check_period 24x7
event_handler_enabled 1
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
notification_interval 60
notification_period 24x7
first_notification_delay 15
register 0
}
Code: Select all
define service {
name base_service
service_description Base service sourced by others
display_name Base template for most templates
is_volatile 0
max_check_attempts 4
check_interval 5
retry_interval 1
active_checks_enabled 1
passive_checks_enabled 1
check_period 24x7
parallelize_check 1
obsess_over_service 0
check_freshness 0
event_handler_enabled 1
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
notification_interval 60
first_notification_delay 15
notification_period 24x7
notification_options w,c,u,
register 0
}
