Hi,

I'm trying to trace a jvm using the hotspot provider. I've enabled the flag ExtendedDTraceProbes for the running process:

/opt/j2sdk-1.6.0.16/bin/amd64/jinfo -flag +ExtendedDTraceProbes 25255

But I didn't get the expected result:

dtrace -n 'hostspot$1::: {} ' 25255
dtrace: invalid probe specifier hostspot$1::: {} : probe description hostspot25255::: does not match any probes


I've tried to trace another jvm in the same way and it works smoothly.

Did you spell hotspot correctly?

There is no probe 'hostspot' at all.
