| 37 | * Usage: |
| 38 | * 1. hotspot_calls_tree.d -c "java ..." |
| 39 | * 2. hotspot_calls_tree.d -p JAVA_PID |
| 40 | * |
| 41 | * This script prints calls tree of fired 'hotspot' probes. |
| 42 | * |
| 43 | * Notes: |
| 44 | * The script uses 'monitors' probes which are disabled by default since |
| 45 | * it incurs performance overhead to the application. To enable them, you |
| 46 | * need to turn on the ExtendedDTraceProbes VM option. You can either |
| 47 | * start the application with -XX:+ExtendedDTraceProbes option or use the |
| 48 | * jinfo command to enable it at runtime as follows: |
| 49 | * |
| 50 | * jinfo -flag +ExtendedDTraceProbes <java_pid> |
