Hi,
I am able to compile OpenJDK9 with dtrace on Linux container with Ubuntu \
distribution (but still having compilation issues on host machine).
Now as I went a step a head, I tried to test "method__entry" marker. Below is the \
script
probe process("JDK_PATH/lib/amd64/server/libjvm.so").mark("thread__start") {
printf("Marker thread__start [%s] %d %d %d %d\n", \
user_string($arg1),$arg2,$arg3,$arg4,$arg5); }
Note: Need to replace JDK_PATH with actual path.
above script did run and I did got output as below
Marker thread__start [Reference Handler] 17 2 21151 1
....
....
But I am not able to use hotspot provider i.e. below script does not run
stap -e 'probe hotspot.thread_* { printf("%s: %s%s\n", ctime(gettimeofday_s()), name, \
thread_name) }' \ -c 'java Hello'
And I end up in below erorr
semantic error: while resolving probe point: identifier 'hotspot' at <input>:1:7
source: probe hotspot.thread_* { printf("%s: %s%s\n", \
ctime(gettimeofday_s()), name, thread_name) } ^
semantic error: probe point mismatch (similar: oneshot, tcp, init, scsi, stap): \
identifier 'hotspot' at :1:7
source: probe hotspot.thread_* { printf("%s: %s%s\n", \
ctime(gettimeofday_s()), name, thread_name) } ^
Can some one point me to where I can get hotspot provider or am I missing something.
thanks and regards,
Mahesh Pujari
