# Deploying a custom properties file

By default, the Data Service Runner updates the application.properties file for the microservices that it installs. If you have created a custom properties file, you must change the default setting to deploy it.

## Before you begin

You have created a custom application.properties file.

## Procedure

1. Open <RemoteEngineInstallationDirectory>/etc/org.talend.ipaas.rt.dsrunner.metrics.collector.cfg.
2. Modify the ms.custom.application.properties command line as follows:
   ```
   ms.custom.application.properties=<path_to_the_new_properties_file>
   ```

   This command line instructs the Data Service Runner to deploy the defined file.
3. Save the file.
