The websphere active "thread pool max" metric has a decimal point in customer chart

owen_chen — Wed, 31 May 2023 14:55:50 GMT

I have setting a websphere Active threads(Max) in customer chart.

But why does the active thread (Max) have a non-positive integer value? This is very strange to me. Has anyone encountered it before or can answer me why such a value appears?

Hi,

ActiveCount is a BoundedRangeStatistic in PMI, so it may have a scale. A scale less than 1 can produce a fraction. Please check your PMI values in the Websphere performance viewer.

Hi,

https://www.ibm.com/docs/en/was-nd/8.5.5?topic=SSAW57_8.5.5/com.ibm.websphere.javadoc.doc/web/apidocs/com/ibm/websphere/pmi/stat/WSThreadPoolStats.html

I refer to this file and see that the static value of Active thread is "int", so I think the value should be an integer.

Or does Dynatrace process the values again?

Hi,

The value itself is int, but in PMI you can define a scale. If the scale is not an int, the result of activeCount will be decimal. Please check in the WAS admin console -> performance viewer.
