This is a plugin to monitor a Dell Equallogic storage device with Nagios. Its written in shell so it should run on almost all Linux/Unix based systems. It's using SNMP (v2) to query the informations from the Equallogic device. To be able to use the script, please also check the requirements.

** Compatibility ** ---------------------------------------------------- The plugin has been successfully tested on the following Dell Equallogic devices: [Please see up to date table on http://www.claudiokuenzler.com/nagios-plugins/check_equallogic.php]
** Requirements ** ---------------------------------------------------- - The following shell commands must exist and be executable by your Nagios user: snmpwalk, awk, grep, wc - SNMP must be enabled on the Dell Equallogic device. If it is not already, enable it on the member.
** Definition of parameters ** ---------------------------------------------------- -H Hostname or IP address of Equallogic to check -C SNMP Communityname (must be at least readable) -t Type of check you want to do (see the definition of types further down) -v Name of single volume to check [-w] Warning threshold (optional and only in combination with certain types) [-c] Critical threshold (optional and only in combination with certain types) --help Help text for correct usage of this script
** Definition of the check types ** ---------------------------------------------------- conn -> Checks number of current ISCSI connections (thresholds possible) disk -> Checks Status of all disks diskusage -> Checks how much raid space is already used (thresholds possible) etherrors -> Checks ethernet interfaces for ethernet packet errors ethif -> Checks status of ethernet interfaces (thresholds possible) fan -> Checks status of fans health -> Checks overall health of Equallogic device info -> Shows general information of Equallogic device memberusage -> Shows disk utilisation of all members of the same group (thresholds possible) poolconn -> Check highest number of ISCSI connections per pool (thresholds possible) poolusage -> Checks utilization of pools (thresholds possible) ps -> Checks status of power supply(ies) raid -> Checks RAID status snapshots -> Checks Snapshot Reserve status (warning level is taken from the equallogic volume config, critical level can be set with -c ) temp -> Checks temperature sensors uptime -> Shows uptime of Equallogic device vol -> Checks a single volume, must be used with -v option (thresholds possible) volumes -> Checks utilization of all created ISCSI volumes (thresholds possible)
We have two PS6210X chassis that we monitor with this wonderful plugin, could not be happier since it covers all the important aspects of the EqualLogic SAN.
Every check works correctly. Good work on this.
This plugin works great for my 2 member pool. Thank you very much for the work done!
Thanks for the excellent plugin and documentation on your site. Please keep up the good work :-).
Hi Claudio, Thanks for the plugin! Works great on my ubuntu Nagios box. I am only having trouble with one service check that specifically check one volume. I get the following error message: ./check_equallogic.sh: line 804: / 1024: syntax error: operand expected (error token is "/ 1024") Do you know where this error is coming from? I've tried several options I googled but I cannot get this check fixed. As this is the best plugin for equallogic I would like to get this working :). Thanks!
Fixed in version 20150203.
your plugin is perfect. I'm only getting a little issue with volume resquest. If my volume is stored on more than 1 eql, it fails with the UNKNOWN error. I've try to debug it, but I'm not good as I want in shell script. I can help you with send you any snmp info if you don't have 2 eql to made this test.
Yes, please contact me on www.claudiokuenzler.com
Thanks for submitting this. I had two Equallogic SANs that I needed to monitor. Do you think you will update this with an option to also monitor I/O usage on a percentage scale? It would be great to know what our daily I/O is off the SAN.
This is very useful for my PS6000E's, however I can't seem to get the Ethernet Errors check to work properly. Even using the default check command in your example returns a critical status even if there's only a single packet error. Is there a fix for this?
I see where this could be improved. Please contact me on www.claudiokuenzler.com to analyze this together.
Great work..works very well. However would like know if anyone has come across this problem like mine..I have storage group of 6 member SAN boxes..plugin monitors them well but if any member is offline it shows health OK with 5 members whereas group console shows critical errors due to member offline..Not sure if I am missing something.
You probably refer to the health check? I've actually never seen it become critical, even when a disk fails. Might as well remove that check as it doesn't seem to be a real reference...
Excellent plugin, works great on PS4000
This plugin works great on GWOS CE. I got it to with with two different EqualLogic units, 4000x and 5000xv. One area of improvement will be FAN and PS. Currently, FAN and PS shows all the FANs and PS for both Equallogic appliances inside the group, no matter what IP address is given. It will be great if shows these components separately. This way we know for example the PS unit which is failed is coming from which Equallogic box. I still love this plugin very much as I don't need to enable Email notifications anymore .. Thank You!
I know, this is bugging. I've talked with one of the Engineers of the Equallogic about that 'problem' but this is the 'Equallogic design'. So every member is giving out information for all other members in the same group. Helpful for volume checks but annoying for hardware related checks like PS, I agree.
I am using this plugin with a PS400, PS5000 and a PS6000 and it works absolutely great!! When your Equallogic boxes are setup in a group like mine are, service checks like diskstatus/powersupplies/volumes wil give you values from the group combined, even though your host ip is an interface on one of your SAN's. i.e. diskstatus gives a value like "DISK OK 42 disks OK 4 disks spare"
I am using this plugin with a PS4000 and a PS6010 and it works great. The plugin is still under development, so check the project website frequently!
Works great! Has everything I wanted. I just spoke with the developer and if you are running Nagios on Ubuntu, you may have to change the first line to be #!/bin/bash, instead of #!/bin/sh to get the interfaces check to work properly.
