Sun GlassFish Enterprise Manager DTrace Monitoring 3.0 Beta Installation and Quick Start Guide

Obtaining Information About Enterprise Server DTrace Probes

Information about Enterprise Server DTrace probes enables you to determine the DTrace probes to use for monitoring the aspects of Enterprise Server performance that are of interest to you.

You can obtain information about Enterprise Server DTrace probes by using the following software:

Using DTrace to Obtain Information About Enterprise Server DTrace Probes

You can obtain information about Enterprise Server DTrace probes by using the dtrace command with appropriate options to list the probes that are of interest to you.

Example 1 Listing All Enterprise Server DTrace Probes

This examples uses the -l option and the -P option of the dtrace command to list all Enterprise Server DTrace probes.

In this example, the process ID of the Enterprise Server process is 755.

For better readability, the spacing between columns is reduced and some probes that would listed by this example are not shown.

Using Monitoring Scripting Client to Obtain Information About Enterprise Server DTrace Probes

If you have installed Monitoring Scripting Client, you can obtain detailed information about each Enterprise Server DTrace probe. This information includes a description of the probe, an explanation of what causes the probe to be fired, and a description of the probe's parameters. This information is not available through standard DTrace tools.
