Let’s assume that one of your vCD cells is using a bit of CPU and you are curious what actual task inside of vCD is requiring all of those resources. Here’s how you can find out.
Get the PID from “top –H –u vcloud”; this is the specific task in vCD as opposed to the vCD general process you will find later. In my case the PID = 16225
Convert this PID to Hex = 3F61 or 0x3F61
Find the vCD Java Process; “ps –auxf |grep vcloud” should return at least 2 results. You want the process that has /opt/vmware/vcloud-director/jre/bin/java.
Get a java thread dump with “kill –3 < vCD Java Process PID>”.
Go search the cell.log (/opt/vmware/vcloud-director/logs) for the Hex value of the process that you are trying to identify. In our case the process we want to investigate is 0x3F61. A quick search for that value brings up the java trace of what vCD is attempting to do.
