SNMP External Monitoring

[Cringer]

I'm setting up system wide monitoring, and would like to include Zimbra in this.
I notice that Zimbra has a SNMP service, but I'm unable to get any response from it.

Is there a way of setting the community names and security?

[Klug]

In order to achieve that (external SNMP monitoring with Cacti), I simply added net-snmp package to my Zimbra servers.

This way, I can get standard metrics (CPU, bandwidth, volumes, RAM, load, etc) from SNMP (on standard ports and co).

The snmp provided by Zimbra
-zimbra-snmp-4.0.4_GA_457.RHEL4_64-20061115174236
doesn't support any sort of snmpd daemon that you can poll from? Is using net-snmp the recommend action for Network Edition/RHEL4 setups? I'd like to use some of the net-snmp information for Cacti.

[Klug]

You can setup the provided snmp daemon for trapping (it's in the doc iirc).
I have not tried to get stats out of it.

[reza225]

which doc are you referring to? when i looked at the admin guide it didn't really give specifics on setting up the traps.

[Cringer]

As Klug recommended, I installed net-snmp.

I can now monitor everything I want, and from what I read. I can probably monitor everything else, when I find I need it.

Good piece of software.

Maybe he meant the net-snmp documentation. What is it you're trying to do? There's nothing in postfix that can be polled by SNMP, you need to make it produce statistics into a file and then 'import' that into something like cacti. IIRC, there's some info on the cacti forum about getting postfix data for graphing.

i just wanted to get some general stats out of my RHEL machine, and saw that Zimbra installed an SNMP pkg but didn't have a daemon running. I'll go ahead and try the net-snmp pkg for RHEL4.

OK, then net-snmp is the package for you. Make sure that you modify the snmpd.conf file so you can access the box that net-snmp is running on. For monitoring the systems I'd recommend cacti, the cacti forums are a good place to look for answers about monitoring.

I would also recommend taking alook at Nagios as well.
