Cisco SAN MDS9020 Switch Port statistics

kwabbernoot

Hi,

I developped a Data Query that allows you to graph statistics on the Fiber Channel ports of a Cisco MDS9020 SAN Switch. The query interrogates the Fiber Alliance (http://www.fiberalliance.org) SNMP MIB v4.0

Remark: The result of the SNMP queries are sometimes in HEX format, therefor the script has a convert function attached. I noticed however that the HEX result can differ between systems. If your graphs remain empty please very the output of the script by executing it manually.
Currently the scripts detects HEX output has the following formats: "HEX-aa:bb:cc:dd:ee:ff:gg:hh:ii" or "aa:bb:cc:dd:ee:ff:gg:hh:ii"

The Data Query was created and tested in Cacti 0.8.6h.
It was exported from Cacti 0.8.6h, imported and currently used in my production Cacti 0.8.6h environment.

To use:
- Take a backup of your current Cacti DB (allows you to return if the import detroys your Cacti environment)
- Import the Data Query Export xml into your Cacti application
- Unzip/untar the attached .tar.gz file
- Place the xml file into "<path_cacti>/resource/script_queries"
- Place the script into "<path_cacti>/scripts"

Regards,

Works great with the following McData SAN switches:
ES-3232 (Sphereon)
ED-6140 (Intrepid)

As you are using the Fiber Alliance MIB, I think you should remove all references to the MDS9020 in the scripts and filename.

Thanks a lot!

I am using the same version (0.8.6h) of cacti, and I have been attempting to use this template to monitor ports on a Cisco MDS9020. when i attatch the template to the device it will not give me the option of selecting any ports as on other switches with SNMP-interfaces.

How do you properly set up the template to allow the ports to actually be monitored?

Sorry for the late reply, but it has been some time since I checked the Cacti forum. If you have a specific question you can always send a private message. The system sends me a mail and I always verify them.

The implementation of the script is explained in the original post.

I could remark however to test the script from command line and if possible interrogate the SAN switch manually using snmpget or another snmp query/walk software.

Like I mention on the script

Sorry, I haven't seen anything like that, but I just wanted to say that I was able to get this working after a bit of a struggle. The heart of the problem that I had was that the php script seems not to work if the snmp version isn't set to 1. We monitor almost all our equipment with v2c, but when the script was run manually, I'd get undefined offset errors, however when I ran it with with version 1 at the command line, everything worked. I changed this under the device within cacti and re-added the script to the device. Lo and behold it populated the correct number of ports. I was also getting 'U' as an output for a while until I realized that I had left a few lines of output from the code up so that I could troubleshoot, once I took them out, the cacti log showed that the script was getting numbered results. AFter that, it was just a matter of deleting the rrd files for the device and letting the poller recreate them. The graphs populated and everything is working great now.

I guess the main point of my ramblings is that you have to use SNMP v 1, at least that's what I learned.

When i try to import the XML template i get always the same error:

Error: XML: Hash version does not exist.

What i can do?

I tried building this on the latest cacti release as of today. snmpwalk works fine from the command line, but not from cmd.php.

Downgraded to cacti-0.8.6j and all worked okay. Not sure what is causing it.
Any tips on troubleshooting this?

Thanks in advance.
