Update 2011-07-10:  Due to a template export error with Cacti, the import was failing for a lot of people. I apologize for taking so long to fix the templates, however they should be fixed now. Thank you to everyone who pointed out the errors and the fix in the comments.

I have made no secret that I use two applications daily to monitor my infrastructure: Nagios and Cacti. I have created a fair number of scripts (and hopefully publishing more soon) to help Nagios monitor the different parts of the infrastructure, however I haven’t published many of my Cacti scripts previously.

One of the most useful is the config that I use to monitor the different protocol stats for volumes. I created an indexed query so that the single script, and accompanying XML file, are capable of monitoring all the volumes, and I can select which graphs to create for each volume. The polling script is loosely based off of the multi-protocol realtime volume statistics script that I created some time ago.

Download the updated template and script(s) here.

Some examples…

Total Operations, Latency
  

CIFS Operations, Latency
  

NFS Operations, Latency
  

iSCSI Operations, Latency
  

Update 2010-07-21: If you are interested in graphing operations and latency for NFS, CIFS, iSCSI, FCP and/or SAN protocols on a per volume basis, you may want to see this post.

Update 2009-07-22: So, I apparently forgot to add the FCP latency graph to the host template before I exported it yesterday. I’ve updated the download, it should be good now.

Update 2009-07-21: As requested by Dave, I have posted an FCP template and script. I have no way of testing them (no FCP…), but I think they should work.

I’m one of those people who has to know everything that is going on inside my infrastructure at all times. ESX, vCenter, MySQL, SQL Server, NetApp…I keep close tabs on all of them using both Cacti and Nagios.

Some people might find it strange that I have both running, but the two applications have very different functions. Cacti is superb at trend analysis and detecting abnormalities after the fact (only occasionally during the event). I use it’s data to determine, for example, when is a good time for Exchange to take an outage based on the number of users connected and the number of RPC requests occurring. Nagios, on the other hand, is extremely well suited to real time monitoring and alerting. It checks different data points at intervals and if it finds one out of the accepted range, it tells me.

Anyway, back to the point. I created these graphs to give me detailed information about CIFS, NFS and iSCSI on my NetApp filers. I have used these against FAS270s, FAS2020s and FAS6030s running OnTAP 7.2.1.1, 7.2.5.1 and/or 7.3.1 with success against them all.

In addition to the below templates I use some additional graphs to track other metrics. Those graphs are available here:

• NetApp Filer: graphing Performance Stats and IO’s (template) (be sure to apply the performance tweak found here)
• NetApp Graphs

As I get time (which is rare) I plan on adding additional graphs, when I do, I will post them here. I would like to get and graph ASIS information, WAFL stats, and space information (raw, formatted, usable, allocated, overhead for the filer as a whole). If anyone has, or knows where to find, these graphs, please let me know!
