Engineering provided additional information on the Call Time (ms) Metric. Looking at
https://docops.ca.com/ca-apm/10-5/en/using/apm-webview/collect-and-analyze-transaction-traces
only says :
Call time (ms)
This value displays the length of the call in milliseconds.
Can I learn some details about the Call Time (ms) metric?
This is how the metric looks like in the Investigator

CallTime: A method's own execution time excluding other methods called from that method.
e.g.:
void methodA() {
//some code here
methodB();
//some code here
methodC();
//some code here
}
So
ART of methodA = callTime of MethodA + ART of MethodB + ART of MethodC
where ART = Average Response Time.
If the method takes significantly lesser amount of time than 1 ms, then APM shows as zero.

There are a few dummy nodes shown for which there is no logic to execute there to generate call time metric. Hence, we show them as zero as in the above image for the below node.
