Subject: [Nagios-users] Problem Executing Passive Checks
Hi
I want to get information for hosts and services when user needs it using
Service Command - Re-schedule the next check of this service in Nagios GUI. I
write submit command in commands.cfg and in services.cfg I define passive
service which is used that command as check command.
I used the sample script provided by Nagios for sending commands to Nagios.
Script successfully execute in terminal but when I initiate from Nagios GUI
using Reschedule Service Command, it gets executed and after that it gets to OK
state with (null) plugin output every time as shown in below nagios logs.
I used the nagios 3.2.2, nagios pugins 1.4.15 and Fedora 12 32bit.
Following is the configuration, nagios log file and sample scripts.
Commands.cfg
define command{
command_name passive_check
command_line /$USER1$/submit_check_result $HOSTNAME$
"$SERVICEDESC$" $ARG1$
}
Services.cfg
define service {
use generic-service ;
your template
host_name anjum
service_description passive_test
is_volatile 1 ; every change is
logged ...
max_check_attempts 1 ; a change is after only 1 try ...
active_checks_enabled 0 ; unset template's default ...
passive_checks_enabled 1 ; ditto ...
check_freshness 0
freshness_threshold 300
notification_options n ; no notifications ...
check_command passive_check
}
Sample Script
echocmd="/bin/echo"
CommandFile="/usr/local/nagios/var/rw/nagios.cmd"
# get the current date/time in seconds since UNIX epoch
datetime=`date +%s`
# create the command line to add to the command file
cmdline="[$datetime] PROCESS_SERVICE_CHECK_RESULT;$1;$2;$3;$4"
# append the command to the end of the command file
`$echocmd $cmdline >> $CommandFile`
Log file

SCHEDULE_FORCED_SVC_CHECK;anjum;passive_test;1314265018

[1314265239] SERVICE ALERT: anjum;passive_test;WARNING;HARD;1;haseeb
[1314265239] SERVICE ALERT: anjum;passive_test;OK;HARD;1;(null)
As mention in above log, after executing my passive check, service alert is
raised and suddenly another service alert with OK state and (null) plugin
output is raised and visible in Nagios GUI.
Looking forward for quick response.
Thanks.
