# Obtaining system information

You can obtain information about the Network Server, such as version and current property values, Java information, and Derby database server information, by using the `sysinfo` utility.

The `sysinfo` utility is available from scripts, the command line, and the NetworkServerControl API.

The following scripts are located in the `$DERBY_HOME/bin` directory. Before running these scripts, make sure that the Derby Network Server is started.

- Run the following script to obtain information about the Network Server on a Windows system:

      NetworkServerControl.bat sysinfo [-h hostname][-p portnumber]

- Run the following script to obtain information about the Network Server on a UNIX system:

      NetworkServerControl sysinfo [-h hostname] [-p portnumber]

For more information on the `sysinfo` utility, see the Derby Tools and Utilities Guide.

You can also use Java Management Extensions (JMX) technology to obtain system information. For details, see Using Java Management Extensions (JMX) technology.

- Obtaining system information by using the command line
  To run sysinfo from the command line, use a command like one of the following while the Network Server is running.
- Obtaining system information by using the API
  The getSysinfo method produces the same information as the sysinfo command.
