# JMX monitoring

You can use an installation of Java Management Extensions (JMX) and the Remote Method Invocation (RMI) connector to monitor the Spotfire Service for Python.

Remove the comment marker and set the properties to connect to JMX using RMI in the custom properties file. To use JMX monitoring, you must provide valid settings for all five of these properties.
Important: Because JMX monitoring requires connecting to the specific IP address of the node, you must create a custom configuration for each node to monitor.

Configuration property | Default setting | Description
--- | --- | ---
`jmx.rmi.username` | None | Set this value to the JMX user name.
`jmx.rmi.password` | None | Set this value to the JMX password.
`jmx.rmi.host` | None | Set this value to the IP address of the host computer (that is, the computer where the node manager and the Spotfire Service for Python are installed.)
`jmx.rmi.port` | `1099` | Set this value to an available port for the RMI connection with JMX.
`jmx.active` | None | Set this value to `TRUE` to activate JMX.
