Ok, here's a question... I've seen all sorts of applications of MRTG and RRDtool to keep track of traffic patterns, but no mention of actual network downtime or uptime.
Perhaps this isn't as big a deal to most users, I don't know. But anyway, my boss would like some stats to show our overall campus networks health/connectivity rates... anyone tried to gather this kind of stats using RRDtool and if so, would you like to share your approach?
I have a crude approach:
1. do an snmpget on a switch
2. based on the response, increment an uptime or downtime counter (both are DS in an rrd)
3. generate graphs showing downtime (percentage) and uptime
your thoughts, comments?
