| * Usage: |

| * 2. hotspot_calls_tree.d -p JAVA_PID |
| * |
| * This script prints calls tree of fired 'hotspot' probes. |
| * |
| * Notes: |
| * The script uses 'monitors' probes which are disabled by default since |
| * it incurs performance overhead to the application. To enable them, you |
| * need to turn on the ExtendedDTraceProbes VM option. You can either |
| * start the application with -XX:+ExtendedDTraceProbes option or use the |
| * jinfo command to enable it at runtime as follows: |
| * |
| * jinfo -flag +ExtendedDTraceProbes <java_pid> |
