Enabling and disabling remote diagnostic logging for the HTTP/TCP proxy

To facilitate troubleshooting, IBM® Rational® Test Control Panel administrators can view, download, and share detailed log events information for the HTTP/TCP 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 Rational Integration Tester proxies.

By default, remote diagnostic logging to Rational Test Control Panel is not enabled in Rational Integration Tester Agent or in the proxies supplied with IBM Rational Test Control Panel.

Depending on the operating system of the computer upon which the HTTP/TCP proxy is installed, there are two ways to enable or disable remote diagnostic logging to Rational Test Control Panel for the HTTP/TCP proxy:

If you are using Unix-like systems, or Microsoft Windows, you can modify the startup file of the proxy, which is located in <Quality Server installation directory>\httptcp.
If you are using Microsoft Windows, you also have the option to enable or disable remote diagnostic logging for the HTTP/TCP proxy by modifying the IBM RIT HTTP Proxy Windows service.
Note: This Windows service is installed if you selected the Install Service and Start on Boot options for the HTTP/TCP proxy while installing Rational Test Control Panel. By default, those settings are selected in IBM Installation Manager,

Procedure

To modify the startup file of the HTTP/TCP proxy, perform the following tasks:

Use a text editor to open the startup.bat file if you are using Microsoft Windows or startup.sh if you are using Unix-like systems.

Table 1. HTTP/TCP proxy startup file locations for enabling or disabling remote proxy logging
Location in `startup.bat` file where you can make changes	Location in `startup.sh` file where you can make changes
`%_RUNJAVA% -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`

Edit the file as shown in the following table:

Table 2. Parameters for enabling and disabling remote diagnostic logging for the HTTP/TCP proxy to Rational Test Control Panel
To:	Change `startup.bat` as follows:	Change `startup.sh` as follows:
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.	`%_RUNJAVA% -Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
Enable remote diagnostic logging at debug level to Rational Test Control Panel and specify the URL for the network log appender. Note: Available levels are error, warning, info, debug, and trace. Instead of entering a specific URL, you can enter `url:auto`.	`%_RUNJAVA% -Dgreenhat.logappender.net.NET=url:http://IP address or host name:port_number/RTCP,level:DEBUG -Dgreenhat.logappender.jul.JUL -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.net.NET=url:http://IP address or host name:port_number/RTCP,level:DEBUG -Dgreenhat.logappender.jul.JUL -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
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.	`%_RUNJAVA% -Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL -Dgreenhat.loginternal=appender -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.net.NET=level:DEBUG -Dgreenhat.logappender.jul.JUL -Dgreenhat.loginternal=appender -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
Enable remote diagnostic logging at error or warning level to Rational Test Control Panel. Note: Default remote log level is warning. Note: The `Java.Util.Logging` (JUL) appender is not present, so there will be no local file logging.	`%_RUNJAVA% -Dgreenhat.logappender.net.NET -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.net.NET -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
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.	`%_RUNJAVA% -Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
Enable console logging at debug level, use detailed layout, and log internal framework events. Note: Internal events will be sent to the console to help diagnose issues within the logging framework.	`%_RUNJAVA% -Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG - Dgreenhat.loginternal=console -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.console.CONSOLE=layout:detailed,level:DEBUG - Dgreenhat.loginternal=console -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`
Disable all logging.	`%_RUNJAVA% -Dgreenhat.logappender.none -Djava.util.logging.config.file=logging.properties -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Address=false -cp ghproxy.jar com.greenhat.proxy.Main`	`"$_RUNJAVA" -Dgreenhat.logappender.none -Djava.util.logging.config.file="$_SCRIPTDIR/logging.properties" -cp "$_SCRIPTDIR/ghproxy.jar" com.greenhat.proxy.Main`

Save and close the file.
Restart the proxy if you selected the Install Service and Start on Boot options for the HTTP/TCP proxy while installing Rational Test Control Panel.

Alternatively, if you are using Microsoft Windows, you can enable remote diagnostic logging for the HTTP/TCP proxy by modifying the IBM RIT HTTP Proxy Windows service as follows:
1. Run editProxyService.bat from an Administrator command prompt.
  The IBM RIT HTTP Proxy Properties window is displayed.
2. Click the Java tab.
3. Under Java Options on the Java tab, find the following default Java parameters:
```
-Djava.util.logging.config.file=<Rational
Test Control Panel installation directory>\httptcp\logging.properties
-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv6Address=false
```
  Add the following new parameters under the default Java parameters:
```
-Dgreenhat.logappender.net.NET=level:DEBUG
-Dgreenhat.logappender.jul.JUL
```
  Note: For information about variations of these parameters, refer to Table 2.
4. Optionally, modify Level on the Logging tab to change the logging level related to the service itself. The default is Error.
5. Click OK.
6. Restart the Windows service. For example, open the Services applet in Control Panel and restart the IBM RIT HTTP Proxy Windows service.

Results

If you are using Microsoft Windows, HTTP/TCP proxy log files are stored in specific locations as shown in the following table:

Table 3. Locations on Microsoft Windows systems where HTTP/TCP proxy logs are stored
Log type	Default location
Process	`C:\Users\<User name>\ghproxy`
Service	`C:\Windows\System32\config\systemprofile\ghproxy`

Note: The locations of the log files depend on settings in the logging.properties file in <Quality Server installation directory>\httptcp.
