FYI, I found the following article helpful in setting up monitoring for my home setup: http://www.markround.com/archives/48-Linux-iostat-monitoring-with-Cacti.html
The article above is written in the context of setting up monitoring via Cacti, but that's simply using rrdtool on the backend and its the same general idea. Basically: # Setup a cronjob to runs every 5 minutes that runs "iostat -dx 30 2" to gather I/O stats for 30 seconds. You could increase the poll-time if you wanted a more accurate snapshot, but getting statistics for a given 30-second block at a time seemed granular enough for my needs. # Parse the results and feed into rrdtool. Since I'm doing remote monitoring, I used the perl script from the above article to create an net-snmp extension that would return the parsed results, so that Cacti can query the stats over SNMP. This gives the I/O stats on a per drive basis (rather than overall pool stats), but you can adapt the idea to whatever you need. -Tony On Tue, Jun 28, 2011 at 10:08 AM, Matt Harrison < iwasinnamuk...@genestate.com> wrote: > Hi list, > > I want to monitor the read and write ops/bandwidth for a couple of pools > and I'm not quite sure how to proceed.
