This text will assume you have enough knowledge and domain of Nagios and Linux, your Nagios is already deployed and it is in an external server (different where you have your Tiki deployment)
First you need to copy the check_tiky scripts. You can download it from https://sourceforge.net/p/tikiwiki/code/HEAD/tree/trunk/doc/devtools/check_tiki.php. This script is written in PHP. Put it on a path you will remember, for example /usr/local/bin. You will need to call it manually to see the options. This document will use some defaults ones, but you will need to put your own values.
Look for your nagios.cfg file, open it and check what directory is pointing the variable cfg_dir. In this case we are going to use /etc/nagios/conf.d/
Create a file at /etc/nagios/conf.d/check_tiki.cfg with the following content:
define command{
command_name check_tiki_bcc
command_line /usr/local/bin/check_tiki.php -u $ARG1$ -c bcc --bccwarn $ARG2$ --bcccrit $ARG3$
}
define command{
command_name check_tiki_searchindex
command_line /usr/local/bin/check_tiki.php -u $ARG1$ -c searchindex --sirwarn $ARG2$ --sircrit $ARG3$
}
define command{
command_name check_tiki_db
command_line /usr/local/bin/check_tiki.php -u $ARG1$ -c db
}
Edit your server definition. Put the following in the proper directory. In our case, it is in the /etc/nagios/objects/servers/ directory. This is a template, your server definition may be much more complex than this.
define host{
use linux-server
host_name trunk.notre.website
alias trunk
}
define service{
use local-service
host_name trunk.notre.website
service_description PING
check_command check_ping!300.0,20%!500.0,60%
notifications_enabled 0
check_interval 10
}
define service{
use local-service
host_name trunk.notre.website
service_description SSH
check_command check_ssh
notifications_enabled 0
}
define service{
use local-service
host_name trunk.notre.website
service_description HTTP
check_command check_http!-H trunk.notre.website
notifications_enabled 1
}
define service{
use local-service
host_name trunk.notre.website
service_description TIKI Op Code Cache
check_command check_tiki_bcc!http://trunk.notre.website/tiki-monitor.php!80!95
notifications_enabled 1
}
define service{
use local-service
host_name trunk.notre.website
service_description TIKI Index
check_command check_tiki_searchindex!http://trunk.notre.website/tiki-monitor.php!80000!95000
notifications_enabled 1
}
define service{
use local-service
host_name trunk.notre.website
service_description TIKI Op Code Cache
check_command check_tiki_db!http://trunk.notre.website/tiki-monitor.php
notifications_enabled 1
}
As optional setup you can put your service dependencies. In this specific case, check_tiki_* depends on HTTP availability.
define servicedependency{
host_name trunk.notre.website
service_description HTTP
dependent_host_name trunk.notre.website
dependent_service_description TIKI Op Code Cache
execution_failure_criteria n
notification_failure_criteria w,u,c
}
define servicedependency{
host_name trunk.notre.website
service_description HTTP
dependent_host_name trunk.notre.website
dependent_service_description TIKI Index
execution_failure_criteria n
notification_failure_criteria w,u,c
}
define servicedependency{
host_name trunk.notre.website
service_description HTTP
dependent_host_name trunk.notre.website
dependent_service_description TIKI DB
execution_failure_criteria n
notification_failure_criteria w,u,c
}
You can check your configuration by executing:
nagios -v /etc/nagios/nagios.cfg
If there is an error, you will be notified. After that, you can restart nagios and new monitoring will start.
This is a great way to get great tools and to encourage ClearCenter (the main developers of ClearOS)
