Cpu usage alerting

[Patrick Murtey]

HI All,

Currently we have the cpu alerting for all devices set to if one out of many cpu  exceeds the threshold then an alarm will be generated. I know you can set the Spectrum system to look at the aggregate total of all the cpu's and generate an alarm instead. Is it possible to leave it setup for the default way of one out of many, but identify only specific devices to alert on the aggregate total of cpu alarm? Or is it strictly all one way, or the other?

 

 

TIA

Patrick,

I believe in 10.2 and above uses the aggregate. I am basing this off the following from the $SPECROOT/SS/CsVendor/Cabletron/EventDisp file:

 

# CPU Threshold alarms to occur based on the
# aggregate utilization of all the instances
0x00010f07 R Aprisma.EventPairTimeAttr, 0x00010f08, "0x00010f09 -:-", 0x12bce
0x00010f09 E 50 A 2, 0x00010f09
0x00010f08 E 50 C 0x00010f09

# Memory Threshold alarms to occur based on the
# aggregate utilization of all the instances
0x00010f0a R Aprisma.EventPairTimeAttr, 0x00010f0b, "0x00010f0c -:-", 0x12bcf
0x00010f0c E 50 A 2, 0x00010f0c
0x00010f0b E 50 C 0x00010f0c

 

For 10.1 and below, you could modify the $SPECROOT/SS/CsVendor/Cabletron/EventDisp file to do one or the other. 

Reference knowledge documents How to change the SPECTRUM CPU/Memory threshold alarming to alarm on the aggregate value and not the individual instance… 

 

Either way, it is global.

 

To do it for individual, I recommend to create a SpectroWatch on the attribute used for CPU utilization for that particular model. Reference knowledge document How can CA Spectrum be used to monitor and alarm on individual CPU and memory for devices?
