[Nagios-users] how macros on event handlers work
Hi,
I'm slightly unsure about how i used event_handler in this situation
[Fri Apr 10 05:38:16 2009];Nagios 3.0.6 starting... (PID=1017)
[Fri Apr 10 05:38:16 2009];Local time is Fri Apr 10 05:38:16 EDT 2009
[Fri Apr 10 05:38:16 2009];LOG VERSION: 2.0

[Fri Apr 10 05:51:16 2009];Warning: The results of service
'check_nagios_cronjob' on host 'remotehost' are stale by 0d 0h 3m 0s
(threshold=0d 0h 10m 0s). I'm forcing an immediate check of the service.
[Fri Apr 10 05:51:21 2009];SERVICE ALERT:
remotehost;check_nagios_cronjob;WARNING;HARD;1;WARNING: no information

[Fri Apr 10 05:51:21 2009];SERVICE EVENT HANDLER:
remotehost;check_nagios_cronjob;(null);(null);(null);check_by_ssh
define command{
command_namecheck_by_ssh
command_line$USER1$/eventhandlers/check_by_ssh.pl
$SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$ $HOSTNAME$
}
define service{
use passive_template
service_description check_nagios_cronjob
hostgroup_name testgroup
check_command i_am_stale
event_handler check_by_ssh
freshness_treshold 600
}
define command{
command_namei_am_stale
command_line$USER1$/check_dummy 1 no information received from
passive check (stale)
}
based on the configuration above, im expecting a passive check to timeout
after 10 mins. Then check_command will kick in, but it just returns
WARNING which is HARD (i've set max_check_attempts to 1). it will then
execute the event_handler, passing the macros $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$ $HOSTNAME$ as argument to
check_by_ssh.pl. But based on the log output above, these macros contain
'null'? i'm not sure why but im pretty sure macros are working since
$HOSTNAME$ was passed correctly.
Please give me a hint on what im missing.
Thanks,
Marc
