Bei meinem letztem Script habe ich die Möglichkeit gehabt die Joomla Versionen 1.5.x bis 3.x zu prüfen. Im Genansatz zu dem anderen Script prüft dieses Script auch fast alle Installierten Versionen der Komponenten und ist in einigen Fällen sogar präziser als die eingebaute Routine bei Joomla.

Da ich mehrere Versionen installiert habe, sollte das Nagios Script einfach auf die verschiedenen Ordner angepasst werden können.

Übersicht:

Mit diesem Nagios Script ist es möglich verschiedene Installationen von Joomla 2.5.x und 3.x zu prüfen, ob diese und die Komponenten auf dem aktuellen Stand sind. Sollte z.B. die Version 2.5.14 installiert sein meldet das Script, dass es die Joomla Version 2.1.16 gibt. Das Script basiert auf bash und wurde unter Ubuntu 12.04 entworfen. Das Script kann einfach in dem Plugin-Ordner von Nagios abgelegt werden. Dieser befindet sich bei einer Nagios 3 Installation unter /usr/lib/nagios/plugins/. Das Script wird später in der commands.cfg von Nagios eingebunden.

Ihr könnt das Script auch auf der Shell einfach testen: ./check_joomla_comp_update.sh <Ordner>

Als <Ordner> wird das Installationsverzeichnis von Joomla angegeben. z.B. joomla. Sollten eure Seiten nicht unter /var/www liegen schreibt einfach den richtigen Ordner in die Variable.

Das Script

	check_joomla_comp_update.sh v.1.8.3
	check_joomla_comp_update.sh v.1.9

check_joomla_comp_update.sh:

commands.cfg

Das Einbinden in die commands.cfg ist simpel. Ich habe das Script ganz unten in die Datei eingefügt:

# 'check_joomla_comp' command definition
define command{
        command_name    check_joomla_comp_version
        command_line    /bin/bash $USER1$/check_joomla_comp_update.sh $ARG1$
        }

Service einbinden

Zum Schluss muss nur noch der check in der services.cfg Datei eingebunden werden.

define service{
        use                  local-service
        host_name            localhost
        service_description  Joomla 2.5 Version and Components
        check_command        check_joomla_comp_version!<Ordner>
        }
