Problem Executing Passive Checks

[Muhammad Haseeb]

In terminal logged in as nagios, check executed successfully but problem arise when I reschedule the service and it gets to OK state.

Is there any problem in executing custom checks using GUI.

How can I execute custom checks from GUI.

Looking forward to your reply.

Try the check from terminal as the same user as GUI and see what happens.

A GUI instigated check may run under a different username than that used in a terminal script.  Were you root in terminal?

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

[1314265019] EXTERNAL COMMAND: SCHEDULE_FORCED_SVC_CHECK;anjum;passive_test;1314265018
[1314265019] EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;anjum;passive_test;1;haseeb
[1314265029] PASSIVE SERVICE CHECK: anjum;passive_test;1;haseeb
[1314265029] SERVICE ALERT: anjum;passive_test;WARNING;HARD;1;haseeb
[1314265029] SERVICE ALERT: anjum;passive_test;OK;HARD;1;(null)
[1314265236] EXTERNAL COMMAND: SCHEDULE_FORCED_SVC_CHECK;anjum;passive_test;1314265235
[1314265236] EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;anjum;passive_test;1;haseeb
[1314265239] PASSIVE SERVICE CHECK: anjum;passive_test;1;haseeb
[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.
