Administering managed Liberty servers

You can start, stop, monitor, and troubleshoot managed Liberty servers by using the administrative console or the wsadmin tool.

Starting or stopping a managed Liberty server by using the console

To start or stop a managed Liberty server by using the console, complete the following steps.

Click Servers > Server Types > WebSphere application servers.
Select the server that you want to manage.
Click Start to start the server or Stop to stop the server.

Managing logs by using the console

Managed Liberty servers inherit logging mechanisms from WebSphere® Application Server.

You can configure the trace specification, maximum log file size, and other settings by using the console:

Click Troubleshooting > Logs and trace.
Select the managed Liberty server that you want to view the logs for.
Configure the Diagnostic trace and Change log detail levels settings.
For more information, see Log and trace settings and Diagnostic trace service in the Network Deployment 9.0.5 documentation.

In 9.0.5.24, the Diagnostic trace panel was replaced with the Log and trace configuration panel. For more information, see Log and trace configuration service settings.

Starting or stopping a managed Liberty server by using scripting

You can start or stop a managed Liberty server by using the wsadmin scripting tool.

In the following examples, node_name is the name of the node where the server is located and server_name is the name of the server that you are starting or stopping.

To start a managed Liberty server, run the AdminControl.startServer command.
```
AdminControl.startServer('server_name', 'node_name')
```
To stop a managed Liberty server, run the AdminControl.stopServer command.
```
AdminControl.stopServer('server_name', 'node_name')
```

Checking server status by using scripting

To check the status of a managed Liberty server, run the following command.

nodeagent = AdminControl.queryNames('type=NodeAgent,process=nodeagent,node=node_name,*')
AdminControl.invoke(nodeagent, 'getProcessStatus', 'server_name')

In this example, node_name is the name of the node where the server is located and server_name is the name of the server that you are checking the status of.
