I've got MRTG running on my network now and it's GREAT! I was reading through the documentation and it seems like you can use this tool for lots of things. I have SNMP setup on all my servers and would like to graph their uptime. Is this possible? I believe the SNMP OID is 2.1.1.3.0 for uptime. I should be able to use that somehow. I'm looking for suggestions as to how I would do this. Thanks!
