Cisco 6500 Graph Gaps

Post by nanner2 »

I have a Cisco 6509 running IOS, and my graphs keep having missing data
and data that does'nt look right. attached is a screen shot of what I'm seeing.
I am using 0.8.6h and cactid 0.8.6g.

Does anyone have any suggestions to fix this?

Are you using 64-bit SNMPv2 counters for those interfaces? Are they Gigabit or higher?

Yes and No

Actually the interface being graphed is a PortChannel Interface which has 4 GigE's on the etherchannel.
This peticular graph is using 32bit counters.
Attached is the 64bit counter version of the graph.

But I still have gaps of missing data in the graphs?

How is that switches CPU utiltization, for the supervisors? Is it high?

cpu usage

Post by nanner2 »

nothing insanely high:

core1#show processes cpu
CPU utilization for five seconds: 0%/0%; one minute: 3%; five minutes: 5%

Yep, that's fine..

What is the timeout currently set for that device? 500ms, I would suggest increasing it to 1000ms and see if that helps.

What are your log's looking like. I would suspect that if you have logging to "low" you have quite a few error's. Please post.

I set the timout on the device to 1000, I'm still having the missing data on the graphs.
Should I set the logging to Medium?, It's currently set to LOW with all three of the the poller options checked.

Hello,

I have a smilar problem with a Cisco PIX 535 running OS 7.x

I get most of the time snmp timeouts when I poll the active PIX, but I get no problem when I poll the standby PIX.

I have the same setup in a test enviroment with no problems - strange

:-?

Figured it out

Post by nanner2 »

The problem ended up being the "Downed Host Detection" under settings -> poller. For Some reason after changing it from snmp+ping to snmp my graph gaps went away.
