###Usage
Virtualmin virtual server quota check plugin for Nagios
Version v1.0.0
Arguments : -d <domain> -t <type:server|user> -c <critical_threshold> -w <warning_threshold>
-d domain: domain of the virtual serer to query (required)
-t type (server|user): type of quoat to check, defaults to "server"
-c critical threshold level: quota usage threshold for critical alert, in percent defaults to 95
-w warning threshold level: quota usage threshold for warning alert, in percent defaults to 90
The Virtualmin CLI tool is required to run as root thus this plugin relies on sudo. To allow the nagios user (or the one that runs your Nagios or nagios-nrpe-server process) you need to whitelist /usr/sbin/virtualmin the following command for each checked domain:
nagios ALL=(root) NOPASSWD: /usr/sbin/virtualmin list-domains --multiline --domain example.com
It is possible to whitelist the command with any argument so that you do not have to add a new record for every domain but you have to be extremly cautious with this.
