Hi, I am trying to define SNMP threholds within our customers network.
Unfortunately, the hardware in the estate covers everything from 6500s, 7204s to 837's. I've been searching within Cisco website for CPU/Memory/Buffer recommendations but while I've found lots of useful information not exactly what I am looking for.
I realise that the services, routing protocols, importance of each device will have a bearing on my thresholds but even if I had a starting point with a Cisco minimum recommendation document, it would help me.
Re: Cisco recommendations for CPU, Memory, Buffers
You are correct that coming up with hard numbers really depends on the platform, traffic load, features, etc. In general, CPU at 70% would be a minor alert, 80% a major alert, 90% a critical alert. With buffers, at 65% (in use) is a minor alert, 70% is a major alert, and 75% is a critical alert (this data is actually used by the Embedded Resource Manager to do buffer memory reclamation in 12.4(6)T and higher). With memory, 30% free is a minor alert, 25% is a major alert, and 15% is a critical alert.
As for a document for this, I don't know of one. These kind of general numbers are either used within IOS itself, or by our Device Fault Manager application to provide default thresholds.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
