Why JVM GC time spent shows "zero" ?

[Selvam_Sekar]

Hello Community,

I have created JVM GC total time spent dashboard and few of the process groups the GC time spent value is zero.

Could you please help me to understand?  

GC time spent Zero means, GC didn't happen ?

You have here an explanation about all JVM built metrics. Which one are you using in the dashboard @Selvam_Sekar?

Best regards

Then, answering to your question is yes, Zero means, 0 means GC didn't happen.
