Generating a Liberty server dump from the command line
From the command line, you can use the server dump or server javadump command to capture status information for a Liberty server.
About this task
The server dump command is useful for problem diagnosis of a Liberty server because the result file contains server configuration, log information, and details of the deployed applications in the workarea directory. The command can be applied to either a running or a stopped server.
For
a running server, the following information is also included:
- State of each OSGi bundle in the server
- Wiring information for each OSGi bundle in the server
- Component list that is managed by the Service Component Runtime (SCR) environment
- Detailed information of each component from SCR
- Configuration administration data of each OSGi bundle
- Information about registered OSGi services
- Runtime environment settings such as Java™ virtual machine (JVM), heap size, operating system, thread information, and network status
