Nagios Support Forum

Hello fellow Nagios XI users. I have created an EMC CLARiiON Monitoring Wizard that is available for download from the Nagios Exchange.

This Wizard allows you to monitor an EMC CLARiiON SAN.

You can monitor the following components of the SAN:
* Storage Processors = Status of each SP
* Storage Processors Information = Gets information on the SP (SP ID, Agent Revision, FLARE Revision, PROM Revision, Model/Type, Memory and Serial Number
* Storage Processors Busy Percentage = SP Busy % with performance data for graphing purposes
* Disks = Status of the Physical Disks attached in all the Disk Array Enclosures
* Cache = Status of the Read and Write Cache
* Faults = Report any Faults on the SAN
* Percentage Dirty Pages in Cache = % Dirty Pages in Cache with Performance Data for graphing purposes
* Port State = Status of the Ports on an SP
* HBA State = Status of a client's host bust adapter connection
* LUNs = Check the status of a specific LUN and reports State, ID, Name, Size, Free Space, RAID Group Type and Percentage Rebuilt
* RAID Group = Checks the status of a specific RAID Group and reports the State, ID, RAID Group Type, Logical Size, Free Space, Percentage Defragmentation Complete and Percentage Expansion Complete

The monitoring of the EMC CLARiiON is performed by a MODIFIED version of the check_emc_clariion.pl plugin written by Michael Streb @ NETWAYS GmbH.
Further information on this script is located at: http://exchange.nagios.org/directory/Pl ... 93/details

NOTE: My EMC CLARiiON will soon be out of warranty AND due to an office relocation around July 2013 I will no longer have access to an EMC CLARiiON to continue working on this project. Hence this project will need a new owner, anyone wanting to take it on please email me.

Version Notes:
2011-01-01
* Initial release, tested on Nagios XI 2009R1.3G

2011-03-28
* Added Storage Processors Busy Percentage, Storage Processors Idle Percentage and Percentage Dirty Pages in Cache
* Added GNU License

2011-05-08
* Modified plugin to perform an SP Busy check [that uses the controller busy and idle ticks] and returns performance data (sp_cbt_busy). This is more accurate than the (sp_busy and sp_idle) method.

2011-07-18
* Modified the plugin sp_cbt_busy check so it avoids spikes in graphs by checking for invalid values such as "less than 0" or "greater than 100%".
* NOTE: You may need to delete the existing check_emc_clariion.pl plugin from the Manage Plugins page for the plugin to be correctly updated

2013-02-10
* Tested on Nagios XI 2012R1.4
* Updated Wizard to follow wizard coding best practices
* Updated Wizard to include new checks in the updated check_emc_clariion.pl plugin (new SP Information, LUNs and RAID Groups checks)
* check_emc_clariion.pl plugin version 2013-02-09 comes as part of this wizard
* Added functionality to test the EMC CLARiiON monitoring account to ensure it will work when services are added
* LUNs and RAID Groups checks will populate a list of all the LUNs or RAID Groups that are on the SAN you are going to monitor
* Updated installation steps for Navisphere server software and also un-installation steps if you have a previous version
* Added a Troubleshooting / Known Problems section
* Added ability to select existing SP Host objects on Step 2 of the wizard, makes it easier when coming back later to add more services


Any questions / suggestions / requests are always welcome.

I don't even really know what that is, but cool as always

Cheers

Excellent, much appreciated

It's my pleasure

Shh - you're confusing our "open threads" check

Hi everyone,

Currently testing NagiosXI, i am trying to use this wizard, but i guess i have missed something. I have tryied to find any clue on how to make it work, whitout any result. Is there any preconfiguration to do in Navisphere apart creating a monitoring user ? Of course NagiosXI can ping the SPs, and below are the results of the services:

EMC CLARiiON - SPA Port State via SPA
Unknown 15h 44m 14s 5/5 2011-02-22 02:49:25 UNKNOWN: specified port not found -1

EMC CLARiiON - SPA Status via SPA
Unknown 15h 43m 4s 5/5 2011-02-22 02:50:00 UNKNOWN: No output from /opt/Navisphere/bin/navicli

EMC CLARiiON - SPB Port State via SPA
Unknown 15h 42m 9s 5/5 2011-02-22 02:50:55 UNKNOWN: specified port not found -1

EMC CLARiiON - SPB Status via SPA
Unknown 15h 41m 13s 5/5 2011-02-22 02:51:51 UNKNOWN: No output from /opt/Navisphere/bin/navicli

EMC CLARiiON - Status of All Disks via SPA
Unknown 15h 40m 18s 5/5 2011-02-22 02:52:46 No disk were founded !

EMC CLARiiON - Status of Any Faults via SPA
Unknown 15h 39m 22s 5/5 2011-02-22 02:53:42 No output from the command Faults -list !

EMC CLARiiON - Status of Cache via SPA
Unknown 15h 43m 49s 5/5 2011-02-22 02:49:15 No output from the command getcache !

I found on Google that i might need to install NaviSphere on the NagiosXI server. Is that the true ? Is there a way to avoid this installation as i do not need it ?

This is correct, it is how the nagios server communicates with the SAN. There are full instructions in the wizard that explain how to do this.

Please let me know it you need any more help with this.

Since Navisphere has its own monitoring and reporting tools why do I need this wizard then? I was looking forward to trying that until I read that.......
