so, I have a number of routers and switches. I want to graph interface utilization and errors for them.
What is the best way to do that?
I am graphing all the interfaces on our 6 Cisco 6500 switches (another 2 by next week), 2 7600s, a 7200 router, and 4 PIX firewall pairs (6 other pairs need IOS upgrades before they will have any interface data to graph) with devmon, using the devmon rrd collector module shipped as a patch in the 0.3.0. final release.
$ ls /var/lib/hobbit/rrd/*/if_load*.rrd|wc -l 1487
I am not currently graphing errors, but it should be relatively easy. Add the rrd option to the table in the message file for the test, add 'if_err=devmon' to TEST2RRD (you should kill the hobbitd_rrd to get it to restart with this environment variable updated), and create a graph configuration for if_err (would be relatively similar to the one for if_load shipped in extras/devmon-graph.cfg).
I am actually more interested in adding graphs for discards on the firewall templates (as our internet-facing firewall has quite a high discard rate).
I have some other changes to make to the templates, so if error and discard graphs are of interest to others, I can probably get a new template release out pretty soon.
