If you want to capture User Sessions
The extension can be reduced to only ingest metrics into Dynatrace - if this is your case, skip this step.
However, if you choose to also create User Sessions and Actions, you must first create a Custom Application to receive this data. This is because the data is communicated using OpenKit.
Follow these steps:
- Go to Deploy Dynatrace
- Click on Monitor a custom application
- Give your application a name, choose one of the icons, and click Monitor custom application
- On the page that opens, go to Instrumentation wizard and copy the Beacon URL and Application ID (you will need these at a later step)

Levels of configuration
OneAgent extensions allow for two levels of configuration: global or per host. Every host capable of running the extension will use the global configuration unless it is configured to override it with its own configuration.
Configurations can be found in the following places:
- Global configuration: Go to Settings > Monitored technologies > Custom extensions tab and click on the extension name from the list. On the page that opens click Edit global configuration.

- Host-level configuration: Go to Hosts then click on the Host to configure. Click ‘…’ > Settings and expand the row with the extension name. Click Use host configuration.
Configuration parameters
Regardless of the option chosen above, the configuration is the performed the same way.

What is Reduced DEM consumption?
With this option enabled, after the first 30 minutes of a User's session, the frequency of reporting User Actions is reduced to once every 5 minutes, and after the 2-hour mark actions are reported every 10 minutes to reduce the total amount of DEM units consumed.
Note: this only affects the user actions for performance measurements which are normally reported as 3 per minute. The flow of user sessions is not affected by this setting.
For example:
