Solved: OID for "output queue drops" ?

scrye · ‎11-05-2010

Hi All!

We use Zenoss Enterprise to monitor our ~ 3200 Cisco devices. We have successfully been able to use OIDs such as 1.3.6.1.2.1.2.2.1.20 and 1.3.6.1.2.1.2.2.1.14 to keep an eye on ifInErrors and ifOutErrors. However, we need to monitor the transmit output queue drops, i.e. the stat reported via sh int <interface> :

...

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 405496

...

Please be gentle with me - I am NOT a SNMP guru. (I think it ought to be called CNMP - Complex Network Management Protocol ;-) . But, a starting point would be an OID that reports that value, even if it is a simple counter, we can take it from there.

Here's a screen shot of the Performance Template that is workin for montitoring other data:

Thanks!

ifOutDiscards is a good object, but won't necessarily be the same as queue drops. ifOutDiscards could be packets that were dropped because one tried to telnet to a device where only SSH was enabled. Just be aware that the show command output may not line up with what you are graphing via SNMP.

Just so you know I'm not sitting here helplessly waiting, I've been searching using this tool:

http://tools.cisco.com/Support/SNMP/public.jsp

Man, there are a lot of OIDs!

Success! Found it here:

Thanks for being there for me, people - no really, I'm never sarcastic. Sometimes nothing does the trick like a little peer pressure combined with Mr. Google. This is a great forum with a very easy to use engine.

While the object you found may work on some devices, it is deprecated and could be removed in newer versions of IOS. You should also try

1.3.6.1.4.1.9.9.276.1.1.1.1.11 and use it if supported by your devices.

scrye · ‎11-07-2010

Thanks Joseph!

Interesting you mention that OID - it was the first one I tried, but when I did the SNMP walk, the 3560 reported no can do.

We are running the following on most of our 3560s:

Cisco IOS Software, C3560 Software (C3560-IPBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2)

Any insight greatly appreciated!

Joe Clarke · ‎11-07-2010

That version of IOS does support this MIB, and the object really should be there. I see it in 12.2(50)SE, but I don't have a switching 12.2(46)SE to verify. However, if cieIfOutputQueueDrops is not working for you in a particular version of IOS, you can stick with locIfOutputQueueDrops. Just be aware that both objects exist, and opt for cieIfOutputQueueDrops if it works.

scrye · ‎11-10-2010

I found a better OID!

1.3.6.1.2.1.2.2.1.19 . This page was a big help: http://www.cisco.com/en/US/tech/tk648/tk362/technologies_q_and_a_item09186a00800b69ac.shtml

The previous OID returned INTEGER values, which was greatly confusing Zenoss and the rrd tool. 1.3.6.1.2.1.2.2.1.19 returns COUNTER32, and now the graphs are working for GAUGE type with MAX consolidation. After I'm sure everything is stable I will try DERIVE, so that I see spikes when the errors happen (instead of just the horizontal line representing the current value of the counter), and can set thresholds for alarms.

Some results:

ifOutDiscards is a good object, but won't necessarily be the same as queue drops. ifOutDiscards could be packets that were dropped because one tried to telnet to a device where only SSH was enabled. Just be aware that the show command output may not line up with what you are graphing via SNMP.

thanks, I really appreciate the info.

I have fresh info regarding the OID you recommended - not sure why, but it is working now! (Perhaps a typo when I first tried it?)

Do you know why this OID returns the SNMPv2-SMI::enterprises literal instead of IF-MIB::ifOutDiscards ? Should that worry me?

Joe Clarke · ‎11-13-2010

Because you do not have the CISCO-IF-EXTENSION-MIB loaded. No, this is not a problem. As long as you have the correct OID, you will be able to poll it.
