To Install DTrace Monitoring

Before You Begin

Ensure that the following prerequisites are met:

• The DTrace Monitoring distribution file is downloaded from the Sun GlassFish Enterprise Manager DTrace Monitoring download page.

• The following software is installed on your machine:

  • Sun GlassFish Enterprise Server v3

  • JDK^TM release 7

• Enterprise Server uses JDK release 7.

JDK release 7 is available for download from the Java Early Access Downloads site.

1. Change to the directory to which you downloaded the ZIP file.

   cd download-dir

   download-dir is the directory where you downloaded the ZIP file.

2. Unzip the ZIP file.

   unzip monitoring_dtrace-3_0-beta.zip

   When you unzip the file, a directory that is named monitoring_dtrace is created within the current directory. This new directory contains a subdirectory that is named lib, which contains the glassfish-dtrace.jar file.

3. Copy the glassfish-dtrace.jar file to the Enterprise Server modules directory.

   cp monitoring_dtrace/lib/glassfish-dtrace.jar as-install/modules

   as-install is the directory in which Enterprise Server is installed.

4. If necessary, start an administrative domain.

   asadmin start-domain domain

   domain is the name of the administrative domain to start.

5. Enable support for DTrace monitoring in Enterprise Server.

   asadmin set configs.config.server-config.monitoring-service.dtrace-enabled=true
