CPU Question for Cisco Cat 6509 switches

Regarding the CPU (Min/Max/Average) CPU load Graph for the node details. How is this calculated? is it using a Cisco vendor MIB? What is difference between this metric and the metric from the Cisco MIB Old-Cisco-CPU-MIB-avgBusy5 (1.3.6.1.4.1.9.2.1.58) Some of my network engineering are claiming that the CPU graph stats from CPU Load (Min/Max/Average) are not the same as the stats are done from the switch command link... (i.e. show processes cpu)

It depends on the device, but yes we use the Cisco vendor MIB. We attempt the newer MIB first and if that does not respond, we attempt the older version, but below are the OID's we use.

Newer Cisco CPU:

OID_cpmCPUTotal1min = "1.3.6.1.4.1.9.9.109.1.1.1.1.4"
OID_cpmCPUTotal5min = "1.3.6.1.4.1.9.9.109.1.1.1.1.5"
OID_cpmCPUTotal1minRev = "1.3.6.1.4.1.9.9.109.1.1.1.1.7"
OID_cpmCPUTotal5minRev = "1.3.6.1.4.1.9.9.109.1.1.1.1.8"

Older Cisco CPU:

OID_CiscoAvgBusy1 = "1.3.6.1.4.1.9.2.1.57.0"
OID_CiscoAvgBusy5 = "1.3.6.1.4.1.9.2.1.58.0"

Hi spiky--

Are you MIB walking your device or are you looking at the SW MIB?

M

was doing to two ways, but its ok now it was a currupt mib database, which you guys have now sorted

Hi bshopp

Can I change/set OID manually?

Not for what we poll out of the box. If you want to change or poll something different, you can create a Universal Device Poller to do this.
