Hi Adam,
I tried the -Z option
$> sudo dtrace -Z ./<script>.d
Where <script>.d is
_______________________________________________
#!/usr/sbin/dtrace -s
dvm$target:::method-entry
{
self->ts[copyinstr(arg0),copyinstr(arg1)] = vtimestamp;
}
dvm$target:::method-return
{
@ts[copyinstr(arg0),copyinstr(arg1)] = sum(vtimestamp -
self->ts[copyinstr(arg0),copyinstr(arg1)]);
printf("className %s method name %s", copyinstr(arg0), copyinstr(arg1));
}
_______________________________________________
The command never returns!
I'm no good at D language. I do know C but I need to brush up on my pointers
concepts. The script above was sent to me by another user on the forum and I do
not know if it is correct. Can you please tell me what this program is doing?
I actully need to set up a working POC. I need to get the number of times an
API is called and the total execution time of that API. I need to do this for
boht a stand alone Java application as well as a J2EE app running on WebLogic
8.1 (JDK 1.4.2).
Thanks!

Alteratively, you specify the -Z option to dtrace(1M) which will cause it to
ignore enablings that match no probes. Those probes will later be enabled
once libjvm.so is loaded.
