Nagios configuration for SAN monitoring

[York, Bill, DoIT]

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.

Using the check_brocade_port plugin is not much different to using
check_ping in your default Nagios install.  You need to define the
command, hosts and services in your Nagios configuration files.

If you find the supplied documentation difficult to follow, there are
various books available commercially.  A search for "Nagios" on the
website of your favourite bookstore will no doubt show a few to choose
from.  The book I used to recommend (Nagios by Wolfgang Barth
published by No Starch Press) gives an excellent introduction but
unless it's been updated it won't include a lot of useful stuff new in
version 3.  I'm not sure which book is the best today, but there was a
recent discussion on the topic here on the mailing list.

I use Nagios to receive SNMP traps from the SAN storage manager
software.  I use snmptt to receive the traps and NagTrap to store them
in a database and handle them in the web front-end.  I confess I
haven't tried using the check_brocade plugins.
