%rdy <-> 'VM CPU Ready Time (ms)'

Jump to solution

Hello,

I have a question caused by the conversion of the cpu ready value.

When I'm using extop, the cpu ready is shown as %rdy but when I'm trying to create an alarm trigger, it is shown as 'VM CPU Ready Time (ms)'.

Can you tell me, how I can convert %rdy to rdy (ms)?

Thank you a lot

Tobias

You should configure this per VM as you can't configure a default alarm for all machines. Because vCenter shows the time in ms, but this depends on the amount of vCPU if it's should trigger an alarm or not.

Have a look here, might start you going :

Here is the kb article that tells you how to convert it:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=200218...

  • Realtime: 20 seconds
  • Past Day: 5 minutes (300 seconds)
  • Past Week: 30 minutes (1800 seconds)
  • Past Month: 2 hours (7200 seconds)
  • Past Year: 1 day (86400 seconds)

Just devide the ms by these numbers to get a ruff number to match ESXTOP, it won't be an exact match but it will be close.

I have a ongoing question.

I want to create an alarm trigger, but what is the condition for 10%? Cause i don't know the update intervall of the triggers, i can not solve the formula.

(CPU ready % / 100) * <chart default update interval> * 1000 = CPU summation value


Thanks
