# Enabling JMX on Tomcat

Before being able to connect a JMX console to iObeya, it must be enabled by specifying the following command-line options for Tomcat (environment variable is CATALINA_OPTS in setenv.sh or setenv.bat):

```java
-Dcom.sun.management.jmxremote.port=%my.jmx.port%
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
```

Replace <MY_JMX_PORT> by a port number available allowing remote connection from the JConsole.

> [!NOTE]
> Note:
> 
> Although it is possible to disable authentication by default, we do not recommend doing this in a production environment.
> 
> For detailed information on how to secure your remote JMX connection, refer to the Oracle documentation [here](https://docs.oracle.com/en/java/javase/11/management/monitoring-and-management-using-jmx-technology.html).

You can find the detailed documentation for JMX and Tomcat [here](https://tomcat.apache.org/tomcat-9.0-doc/monitoring.html).
