Freeware and Plugins

Description

check_megaraid_windows is a Windows plugin for Nagios which checks the status of LSI/MegaRaid Raid Controller.
The plugin determines the status of Raidsets, RAID controllers and of individual discs (S.M.A.R.T), while all stripe types are supported.

Requirements

The Mega Raid Command line Tool is installed (MegaCLI.exe).

Documentation

Usually you run the plugin with the path to CLI:

C:> check_megaraid_windows path=<path_to_cli>

For debugging purposes, it may also be called with a more detailed output option (this mode is not suitable for continuous operation, but for testing purposes only).

Afterwards it will output the detailed status of the individual components:

C:> check_megaraid_windows path=“C:\Program Files (x86)\MegaRaid Storage Manager\MegaCLI\MegaCLI.exe“ debug

Installation

Preferably the plugin is copied into the script directory where you will store your checks under Windows

When using NSClient ++ an entry in NSC.INI similar to this is generated and pointed to Mega Raid command line tool:

...
[/modules]
NRPEServer=enabled
CheckExternalScripts=enabled

[/settings/NRPE/server] 
allow arguments=true  

[/settings/external scripts/scripts] 
check_megaraid=scripts\check_megaraid_windows.exe path="c:\Program Files (x86)\MegaRAID Storage Manager\MegaCLI\MegaCli.exe"...

Examples

Check MegaRaid Controller, if everything is all right:

C:> check_megaraid_windows.exe path=“C:\Programme\ICP Storage Manager“
