Hi
Could you enable freshness checking and set the check command to something that
sets the status to critical (for example you could write an external command
into the external command queue)? So long as passive results were received
within the freshness threshold, the check command won't be executed, so the
status you see will be what is reported by the passive check result. If no
passive check results are received you will then be notified of a critical
situation as the freshness check command would then be executed and return a
critical alert.
To this end, I would redefine your passive service command as follows:
define service {
use passive_service
service_description HW Sensors
hostgroup_name hgp_webservers, hgp_db, hgp_search,
hgp_image
check_command check_dummy
active_checks_enabled 0
passive_checks_enabled 1
check_freshness 1
freshness_threshold 300
check_command issue_critical_alert ; this command
is run only if the service results are "stale"
}
Kind regards,
Kris

Subject: [Nagios-users] non sticky passive checks
Hi,
I've configured passive service checks and am reporting back the results using
nsca. I would like to turn the alerts to be critical after 5 minutes if the
monitored servers fail to send any results. Currently the check continues to
remain in the last state. How can I achieve this?
