Deploy Nagios Plugins

nagios core | nagios plugins | nagios ssh

Introduction

those scripts will be used by the nagios agents, but also on the main server (which monitors itself).

install

debian

apt install nagios-plugins nagios-plugins-contrib

slackware

sbopkg -r

we use /bin/bash instead of /sbin/nologin because we need a user shell for check_by_ssh

groupadd -g 213 nagios
useradd -u 213 -g nagios -d /usr/libexec/nagios -s /bin/bash nagios

sbopkg -i nagios-plugins

from source

see nagios plugins source

custom nagios plugins

that one did not work so I went for my own

cd /usr/local/libexec/
wget https://pub.nethence.com/bin/backup/check_temp.ksh.txt
mv check_temp.ksh.txt check_temp.ksh
chmod +x check_temp.ksh

SSH setup

see nagios ssh
