I have, some time ago. It's relatively easy to set up nagios so that
it stores the perf. data in RRD databases. But the problem lies in the
fact that all the performance counters in the brocade switches roll
over after having read or written 4e9 4byte words. So you have to
read-out the counters for each port every 2 to 5 minutes (depending on
the speed of the interface: 1Gb, 2Gb, 4Gb) and if you have a 16-port
FC-switch you have to contact it every 15 seconds. Not a problem if you
have a single switch, but if you have more than, let's say, 8, this will
put a serious load on nagios.
To solve this issue, I wrote a little tool that contacts the FC switches
every minute, retrieves the perf. counters and stores this data directly
into RRD databases (for every port in each switch one RRD db). But every
few minutes it will pass the data through nagios (needed to satisfy
GroundWork).
If needed, I can dig up this tool.
