So, I've been seeing issues since upgrading a bunch of 750 and 750Gs to
5.0rcX, 5.1 and 5.2. I did have to change the OIDs I was graphing, due
to changes in the system, but more worrying is this:
RB750:
Cacti:
vs. Router:
Clearly, the spikes aren't actually occurring. My working theory is that
snmpbulkwalk is causing extremely transient CPU spikes, which it is then
recording. The difference is even worse with RB750Gs:
Cacti:
vs. Router:
although, I do have one 750 which is showing a nearly constant 100% CPU
to cacti, and barely breaking 30% on the router graph. That one is still
on 5.0, while these two are on 5.2. I'll be upgrading the last one
tonight. Mikrotik support claims they can't reproduce my results with
either The Dude or MRTG. Is anyone else seeing anything like this?
