Every time I restart my OpenVPN tunnel it increments interface's number and breaks MRTG graph for the interface.
IF-MIB::ifName.76 = STRING: tun_w
after restart:
IF-MIB::ifName.77 = STRING: tun_w
Any way to fix it?
We have been running MRTG for quite some time to keep an eye on our router usage at remote offices. We now have a need to see roughly how much data (pref in GB) has been transferred over the link.
Can I get MRTG to tell me this info, or am i going to have to use something else?
Cheers Luke
I am using MRTG + RRDtool to monitor the bandwidth on each switchport of a Cisco Catalyst 2950 via snmp. Is MRTG capable of generating an hourly graph? With RRDtool I was able to set the interval to 1 minute in hopes of getting a more detailed graph, but the shortest timeframe the graph is 'Daily' graph (5 Minute Average) and the image is too small.
What I am looking to get out of this: I am looking to be able to visually monitor all of the switch ports and tell when port begins to have unusually high traffic, in real time (1 minute interval of snmp poll, graphs generated, and page refreshed).
Putting together a simple MRTG-like setup to monitor the load on our network switches. I've been told that Cisco switches are set up to be polled every five minutes, but we would like to get more precise readings, maybe once per minute.
Is this something that can be done? Or would we just be storing duplicate data because Cisco only updates it's traffic numbers every five minutes, or because they use a five minute rolling average for their readings?
