NTBackup Nagios Plugin

Overview

Simple plugin for Nagios to test if nightly backups completed successfully.

Prerequisites

• Install NSClient++: http://www.nsclient.org/nscp
• Install ruby: http://rubyinstaller.org/
• Place the .rb scripts in the NSClient++ scripts folder, i.e: C:\Program Files\NSClient++\scripts
• Configure the script as an external script for NSClient++. See the sample below if you need help.
• General information about monitoring Windows machines with Nagios can be found here: http://www.nsclient.org/nscp

Configuration

• Update the BACKUP_DIRECTORY constant in check_nt_backup_config.rb to point to the NTBackup log directory. This directory is in the user profile of the user account that runs NTBackup.
• If you don't run backups every night you may need to adjust the MAX_AGE constant in the script.
• The MAX_AGE array specifies a different number of hours for each day. This is in case you don't run backups on weekends.

Example NSC.ini

In a default installation it will be here: C:\Program Files\NSClient++\

The following is a minimalist NSC.ini file. This will get you up and running but you should probably configure NSC++ with a proper allowed_hosts directive and a password.

NRPEListener.dll
