Network Management System - snmp - Dell OpenManage
I'm looking into network management systems. I installed OpenNMS and played around with it. A little too much command line, and scripting for me. I'm not very experienced with Linux. Now I have Dell OpenManage NMS installed (most of our equipment is Dell). Also seems pretty complex. I'm just now getting into using SNMP. Running into a lot of difficulties.
1. At what size network do you usually start to need a NMS? I don't want to get into managing something like this is it's going to be more work than it's worth.
2. What do I need to do to have a basic setup? I have the NMS monitoring one of my switches with snmpv1, public, read/write. I'm not sure what info i'm supposed to get with that. CPU / Memory utilization? Just that it's up and running? What would be the basic things to accomplish to be monitoring a device using a NMS.
3. I have the options to monitor the device using telnet, snmpv1,2,3, SSH, and a bunch of others. What are the advantages of one over the other? Do I need to use more than one? Which one will be able to tell me everything I would want?
thanks!

Does using Cacti require a lot of script writing and editing? I wasn't too hot on that with OpenNMS. Do you like it better than OpenNMS?
I would love to see how you have it set up. Could we do it tomorrow? I'm in the U.S. Pacific time zone.
Thanks a lot!

I can do tonight any time, I can do tomorrow towards noon (pacific time).
With cacti all the checks are pre-set, so you don't need to get involved into scripting at all.
You'd get more benefit from it, obviously, as you'd be able to monitor more specific things, but don't let scripting scare you. Even some custom checks can easily be scripted.

Awesome. Any time before 3pm today would be great. I am also Pacific time. I don't see a way to IM you on this site. How do we set it up?

Is Cacti free? Any limitations?
Ok so lets say I have Cacti set up and with SNMPv1 I am able to connect and read from one of my Dell switches. Will it grab cpu, memory, etc., or do I need to configure that? How?
What is snmp configured to read by default?
