Enabling and disabling remote diagnostic logging for the Java virtualization proxy

To facilitate troubleshooting, IBM® Rational® Test Control Panel administrators can view, download, and share detailed log events information for the Java™ virtualization proxy. The capability to display this information in Rational Test Control Panel requires enabling remote diagnostic logging for the proxy.

About this task

Rational Test Control Panel can display a diagnostic log that is a centralized view of log events of IBM Rational Integration Tester agents and proxies.

Note: The diagnostic log is available only in Rational Test Control Panel 8.5.1 or later.

Note: Only the Java virtualization proxy supplied with IBM Rational Integration Tester Platform Pack 8.6.0 or later supports remote diagnostic logging to Rational Test Control Panel.

By default, remote diagnostic logging to Rational Test Control Panel is not enabled in the Java virtualization proxy.

To enable or disable remote diagnostic logging for the Java virtualization proxy, you must modify the startup parameters of the application that you want to record or virtualize.

Procedure

Edit the startup parameters as shown in the following table:

Table 1. Parameters for enabling and disabling remote diagnostic logging for the Java virtualization proxy to Rational Test Control Panel
To:	Do the following:
Enable remote diagnostic logging at debug level to Rational Test Control Panel Note: Available levels are error, warning, info, debug, and trace. The `Java.Util.Logging` (JUL) appender defaults to "level:debug" if level is not set, so all events are passed to `Java.Util` and filtered there by the separate configuration.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL`
Enable remote diagnostic logging at debug level to Rational Test Control Panel and specify the URL for the network log appender. Note: Available levels are error, warning, info, debug, and trace. Instead of entering a specific URL, you can enter `url:auto`.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.net.NET=url:http://<IP address or host name>,level:DEBUG -Dgreenhat.logappender.jul.JUL`
Enable remote diagnostic logging at debug level and internal logging to Rational Test Control Panel. Note: Available levels are error, warning, info, debug, and trace.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL -Dgreenhat.loginternal=appender`
Enable remote diagnostic logging at error or warning level to Rational Test Control Panel Note: Default remote log level is warning. Note: The `Java.Util.Logging` (JUL) appender is not present, so there will be no local file logging.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.net.NET`
Enable console logging at debug level and use detailed layout. Note: If Java logging is not enabled, you might want to enable console logging. Console logging layout can be detailed, standard, or compact.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG`
Enable console logging at debug level, use detailed layout, and log internal framework events. Note: Internal events will be sent to the console to help diagnose issues within the logging framework.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG -Dgreenhat.loginternal=console`
Disable all logging.	Edit the invocation command line or the system properties within the Java application as follows: `-Dgreenhat.logappender.none`

Save your changes.
Restart the application as required.
