# Configure Data Admin Logs

You can configure Data Admin to generate an `idol-access.log` file. This log stores information about all the actions sent to Knowledge Discovery component ACI and service ports. It includes the following information:

- the user that sent the query.
- the IP address the user is connecting from.
- the component that the query is sent to (for example, QMS or Content)
- the host and port of the component.
- the full query that is sent to the component.
- the status code that the component returns.
- the time taken to complete the request.

The log also shows requests that failed without returning a HTTP status code (for example, because the component was turned off or blocked by a firewall).

You can turn on logging by setting the `idol.log.enabled` system property.

When you turn on logging, you can optionally turn off the information about time taken to complete requests by setting the `idol.log.timing.enabled` system property.

To turn on logging

- At the command line, send the java run command with the `idol.log.enabled` argument set to true. For example:

      java -Didol.log.enabled=true -Didol.dataadmin.home=[home directory] -Dserver.port=[port] -jar dataadmin.jar

To turn off timing information in the logs

- At the command line, send the java run command with the `idol.log.timing.enabled` argument set to false. For example:

      java -Didol.log.enabled=true -Didol.log.timing.enabled=false -Didol.dataadmin.home=[home directory]  -Dserver.port=[port] -jar dataadmin.jar

If you run Data Admin as a service on Windows, you can also add the `idol.log.enabled` and `idol.log.timing.enabled` properties to the `dataadmin.xml` file.

If you run Data Admin as a service on Linux, you can add the argument to the existing arguments variable in the start scripts (`dataadmin.sh` for SysV, `dataadmin.conf` for Upstart, or `dataadmin.service` for systemd).

When you modify the Data Admin configuration by modifying the XML file or start scripts, you must restart Data Admin to apply your configuration changes.

On Upstart, you must also run `initctl reload-configuration` before you restart, to apply the init file changes. You can then run `service dataadmin restart` to restart the service.

## Use an Action ID

You can optionally configure Data Admin to send an action ID with each request to a Knowledge Discovery component, which can help with tracking and troubleshooting.

When you enable action IDs, Data Admin generates the action ID with a UUID and a prefix, which you can configure. The default prefix is DataAdmin-. For example, `DataAdmin-b17a4a79-b3ed-4706-80a6-06404140e815`.

To use an action ID in requests

- At the command line, send the java run command with the `idol.log.actionid.enabled` argument set to true.

  Optionally set the `idol.log.actionid.prefix` argument to the prefix that you want to use for your action IDs. For example:

      java -Didol.log.actionid.enabled=true -Didol.log.actionid.prefix=DataAdmin- -Didol.dataadmin.home=[home directory]  -Dserver.port=[port] -jar dataadmin.jar

  TIP: This example turns on the action ID without turning on logging, which means that the action ID is displayed in component request logs. To store the action ID in the logs, you can also turn on logging, by adding the `idol.log.enabled` argument.

If you run Data Admin as a service on Windows, you can also add the `idol.log.actionid.enabled` and `idol.log.actionid.prefix` properties to the `dataadmin.xml` file.

If you run Data Admin as a service on Linux, you can add the argument to the existing arguments variable in the start scripts (`dataadmin.sh` for SysV, `dataadmin.conf` for Upstart, or `dataadmind.service` for systemd).

When you modify the Data Admin configuration by modifying the XML file or start scripts, you must restart Data Admin to apply your configuration changes.

On Upstart, you must also run `initctl reload-configuration` before you restart, to apply the init file changes. You can then run `service dataadmin restart` to restart the service.
