Extension Execution Controller custom configuration

The Extension Execution Controller (EEC) can be used standalone, out of the box. This topic explains how to modify your EEC.

Modify the EEC configuration

To modify the EEC configuration, edit the extensionsuser.conf file, which is located at:

Windows: %PROGRAMDATA%\dynatrace\remotepluginmodule\agent\conf\extensionsuser.conf
Linux: /var/lib/dynatrace/remotepluginmodule/agent/conf/extensionsuser.conf

Restart the EEC service

After modifying the extensionsuser.conf, you need to restart the EEC service:

LinuxWindows

To restart the EEC service on a Linux system, run the following commands:

For systems with SystemV:

shell
service extensionsmodule stop
service extensionsmodule start

For systems with systemd:

shell
systemctl stop extensionsmodule
systemctl start extensionsmodule

To restart the EEC service on a Windows system, either start Task Manager and restart the Dynatrace Extensions Controller service or run the following commands:

shell
net stop "Dynatrace Extensions Controller"
net start "Dynatrace Extensions Controller"

Change port used to communicate with ActiveGate

By default, the EEC sends data via port 9999, which is used by ActiveGate.

If you modify the port using the ActiveGate custom.properties file, you also have to modify the port that's used by the EEC. To do so, edit the extensionsuser.conf file to replace PORT with the target port and then restart the EEC service.

ini
Server=https://127.0.0.1:PORT/communication

The port needs to be configured for the ActiveGate plugin module and the EEC.

Enable/disable custom code extensions for data sources

Extensions leveraging sensitive data sources can significantly enhance the functionality and flexibility of your custom monitoring. However, they can also introduce potential vulnerabilities. Disabling custom extensions for these sensitive data sources can significantly reduce the risk of unauthorized access or data leakage.

To enable or disable custom code extensions for a data source

Modify the EEC configuration to replace <DSID> with the data source ID for which you want to enable or disable custom code extensions.
```
json
custom_code_<DSID>_allowed=[True|False]
```
Restart the EEC service.
