Hi Marco,
Thanks for the reply. Yep, I have the vlan module disabled. Specifically though, the slowness shows up in the ports module. Debugged using ./poller.php -h hostname -r -d -m ports. I have checked everything down to the control plane policy on the switch including disabling it while polling even though there were no policy violations. Bottom line is the switch is just slow to respond. Checking the release notes, there were numerous snmp related bug fixes in past code however nothing recent. Going to try stepping though some software updates next to see if anything changes in any more recent code revs.
Regards,
Dan ________________________________________ From: observium [observium-bounces@observium.org] on behalf of Marco Spicuglia [Marco.Spicuglia@reasonnet.com] Sent: Sunday, November 02, 2014 12:42 PM To: observium@observium.org Subject: Re: [Observium] Nexus 5596 polling slowness
Hi Dan,
Nexus are the worst devices in terms of SNMP polling, according to my experience, especially if you are using older firmwares. Discovering is even worse.
Though, I solved the slowness by disabling advanced vlan related MIBs, whose polling data is not represented anyway. Upgrading the devices firmware is also helpful.
Regards, Marco

Hello,
Just curious if anyone else is seeing long polling times for Nexus 5596UP switches. Everything else in our deployment is responding in a timely manner and there are no bottlenecks on the Observium server at this point.
./poller.php: access2-2a.sj2 - 1 devices polled in 243.6 secs
Polling times in the high 200 second range are not uncommon while most all of our other high port density devices are well under 30 seconds. If anyone has found a NXOS software version that works better than others please let me know. We have tried on various software version 5,6 and 7 releases. I can only imagine this is a Cisco issue but thought I'd ask here in case anyone solved it.
Regards,
Dan Bliss
