Module: check_mk Branch: master Commit: 6d9ae3d23878811f183b4112366c14b87089a5cd URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=6d9ae3d2387881… Author: Florian Heigl &lt;fh(a)mathias-kettner.de&gt; Date: Mon Jan 9 18:07:47 2012 +0100 Linux Agent: update URL of MegaCli to better / newer version Linux Agent: add agent part for new check megaraid_bbu New Check: megaraid_bbu - Check the status of battery backup unit in midrange / highend LSI based controllers.

The entry chipsets do not support BBUs. The Linux agent will try find any existing BBUs - if {MegaCli} is found in your search path. + The BBUs might come in various types {(iBBU, BBU)} and also some other vendors are using this RAID chip. It is tested against Intel, Dell, IBM and FSC models. + + The check works by matching the agent output against a dictionary of expected values. If you have MegaCli installed and some values are not detected, it might be neccessary to update your version of MegaCli. + + {MegaCli} can be downloaded from LSI at the following URL {http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/8.02.16_MegaCLI.zip} + + It would be possible to make the warning / critical levels user specifiable. See the check source for this if you have a need to influence those parameters. + +item: + A string "RAID Adapter/BBU" followed by the ID of the adapter as reported by MegaCli. + +inventory: + One item is generated per adapter that has an attached BBU module. + + diff --git a/checks/megaraid_bbu b/checks/megaraid_bbu new file mode 100644 index 0000000..183352b --- /dev/null +++ b/checks/megaraid_bbu @@ -0,0 +1,100 @@ +#!/usr/bin/python +# -*- encoding: utf-8; py-indent-offset: 4 -*- +# +------------------------------------------------------------------+ +# | ____ _ _ __ __ _ __ | +# | / ___| |__ ___ ___| | __ | \/ | |/ / | +# | | | | '_ \ / _ \/ __| |/ / | |\/| | ' / | +# | | |___| | | | __/ (__| < | | | | . \ | +# | \____|_| |_|\___|\___|_|\_\___|_| |_|_|\_\ | +# | | +# | Copyright Mathias Kettner 2012 mk(a)mathias-kettner.de | +# +------------------------------------------------------------------+ +# +# This file is part of Check_MK. +# The official homepage is at http://mathias-kettner.de/check_mk. +# +# check_mk is free software; you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by +# the Free Software Foundation in version 2. check_mk is distributed +# in the hope that it will be useful, but WITHOUT ANY WARRANTY; with- +# out even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE.
