Hi all,

This is just on the order of a 'watch out' notice.

We're currently on 0.15.1.6206, but had the same issue with earlier
versions and with the CE.

We have 5 Cisco 2960Cs that we monitor, and all were taking horrible
amounts of time to poll. Always at least 200 seconds, and often over
300.

After some experiment, we discovered that they apparently don't care to
talk about CEF (Cisco Express Forwarding). If Observium asks them about
it, the CPU usage climbs above 60% and stays there for quite a while.

If I go to the device --> edit --> Modules and disable cicso-cef,
everything is fine. The CPU drops under 5%, and the poll time is 5
seconds or less.

I'm pretty sure we're not losing any useful info, since I don't believe
the 2960Cs support CEF in the first place.

As I said, this is just a heads up.

Observium is a great tool.

Thanks!
