3com switch monitoring
#1
Hi everyone,

does anyone of you monitor a 3COM Officeconnect switch with Pandora FMS 3.0?

Do you monitor some specific information via SNMP?
Do you mind sharing your know ho on this with a newbie? :-)

thanks in advance,

1. Try to locate the MIB for your device,  for 3COM OfficeConnect swith in google:

2. Download a MIB browser, there are a lot of free tools, for example:

http://www.ireasoning.com/mibbrowser.shtml

3. Load the MIB into your mib browser.

4. "Browse" your device with the mib browser, you will need a IP address accesible from your host, and of course the SNMP community (a kind of password) who allow to "read" data remotely.

5. Locate some "items" usable for you, and write it down in numerical format, like 1.3.4.2.5.6.3.23
Thats "weird numbers" are called "OID", and thats what need pandora to grab data from your device.

6. Create a network snmp module (probably incremental data (or generic_data_inc) type), and use the IP of your device, the OID you've collected and the SNMP community.

7. If everything it's ok the first data you willl colect is a 0, wait to collect a second data and data collected will be "items per second". Most SNMP information is given as a incremental data (a delta) and you need to grab at least 2 data to calculate the difference.

I hope this will help to enter to the "marvelous" world of SNMP monitoring. Really is a PITA at first time, but once you get it, all SNMP monitoring it's almost the same, so don't give up! ;-)
