Which NMS app would you recommend?


I am going to start using snmp in order to keep tabs of my ever increasing network/networks...

I am planning on using the built in services (snmpd, and snmpdtrap) that ship with RH Linux 7.2 and 8.0.

Would you recommend this? What NMS app would you recommend?

Depends what you want to do..

NMS = Network Management System

What you pick really depends on how much 'management' you intend to do.

If all you want to do is 'keep tabs on' stuff, then it's not really management - it's more.. monitoring and something like mrtg would do fine.

http://mrtg.hdl.com/mrtg.html

It's able to query your interfaces (via snmp) and produce pretty graphs for them based on things like traffic in / out, errors and so on. You can also use mrtg to monitor *other* things like uptime, cpu usage, disk space and basically anything else that can be monitored by snmp.

I have a squid proxy which mrtg monitors and reports back such useful information as how many pages were returned from the cache, versus how many it had to fetch.

If you want to do more, ie, actually *do* something based on the results of an snmp trap - for instance restart an interface if it detects it's down - you'll need to look elsewhere. I've used Npulse (free) in the past - I believe there's a commercial spin-off called AppAssure now, and Big Brother (free).

If you want to get all corporate and spend money there's OpenView (lots of money) which I currently use and is generally considered the de facto NMS, and I used to use Novell's NMS. I believe there's an open source version of that now called OpenNMS, of which I have zero experience.

If you have scripting abilities, I would definately use net-snmp (http://www.net-snmp.org/). With a little time and effort, you can develop scripts to handle a great deal of the monitoring and management tasks automatically.
