Question about graphing bandwidth with Cacti using a gauge instead of a counter. (Or, suggestions on other snmp graphing tools)
posted by empath to computers & internet (4 answers total)
I'm trying to graph an efm group on an adtran router, which instead of using the typical ifinoctet counter, uses something called Curr15MinRxOctets which is a gauge of the last 15 minutes instead of an incrementing counter.
I've been having a variety of problems getting Cacti to graph this -- starting with the fact that it hangs discovering the thousands of interfaces on the device, and then the only way I can get it to graph that oid at all is by manually creating a datasource for every single interface, which is really unworkable since i have hundreds of these on this router. Also, even with the manually generated graph, the numbers don't seem right at all -- they keep resetting in 15 minute intervals so I think it's not handling the gauge data correctly.
I'm about to give up on using Cacti to do this -- are there other free tools out there that will discover interfaces using any arbitrary oid and graph them?
Is there a book on Cacti out there? The documentation is pretty sparse.
