Linux Load Average Threshold

If you are looking for a way to create a dynamic 'high load' threshold for Linux systems based on CPU count, this is how you can accomplish that goal.

I like to have an optional override by using a cProp or zProp, I really dislike making local templates. They are not scalable and you can easy loose track of them.

If you do not want an overwrite option, skip step 1 and 3.

1. Create device level INT cProperty called cLoadAvg with the default value of 0.

• 

  cProp

1. Open your default Linux template (Default: Devices/Server/Linux/Device)
2. Edit your high load threshold (Default: high load)
3. Change maximum value to (use *100 if using Snmp, remove if using SSH):

here.cLoadAvg*100 if here.cLoadAvg > 0 else here.hw.cpus.countObjects()*100

(Optional - Use if you are not using the cProp)

here.hw.cpus.countObjects()*100

• 

  High Load Threshold

Examples:

• 

  Default High Load Threshold that uses number of CPUs

• 

  High Load Threshold that uses value in cLoadAvg

To override the new threshold, change your cProp to what you would like the Load Average threshold to be.
