Re: [Nagios-users] Nagios configuration for SAN monitoring
Hi, recently got these working and I'll tell you what I've learned. i don't know if it's a bug in the brocade snmp implementation, but getsnmp and check_brocade_port both report an admin down port, even when the port is admin up and the cable is unplugged. this is a problem to me, but i just set up alarms for a WARNING. i use cacti for RRD monitoring. i found PNP too cumbersome. this command is different from the check_ping as it does not use the IP stack for availability. you have to set this up as a service and monitor accordingly. unfortunately, monitoring a FC SAN is much different from monitoring an Ethernet network. bill -Original Message- From: Jim Avery [mailto:j...@jimavery.me.uk] Sent: Mon 2/23/2009 1:02 PM To: nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] Nagios configuration for SAN monitoring 2009/2/21 Sonika Sachdeva replyson...@gmail.com: Hello List, I have nagios basic configuration up and running as per the quickstart guide.

Has someone used nagios for SAN monitoring? 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.

Re: [Nagios-users] Nagios configuration for SAN monitoring
Thanks very much All. Thanks Edgar. Edgar, I think that tool would be very helpful. I am planning to monitor the traffic on 2 brocade switches (224 ports each / 7 blades each) So that would put a lot of load on the server as you mentioned. It would be quite helpful if you could forward that to me.
