To install the Tenable integration configuration on your Agent:

**Note**: This step is not necessary for Agent version >= 7.18.0.

The Agent tails the Tenable Nessus `webserver` and `backend` logs to collect data on Nessus scans.

#### Log collection{% #log-collection %}

*Available for Agent versions >6.0*

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your `datadog.yaml` file:

   ```yaml
   logs_enabled: true
   ```

1. Uncomment and edit this configuration block at the bottom of your `tenable.d/conf.yaml`:

See the [sample tenable.d/conf.yaml](https://github.com/DataDog/integrations-core/blob/master/tenable/datadog_checks/tenable/data/conf.yaml.example) for available configuration options.

   ```yaml
      logs:
       - type: file
         path: /opt/nessus/var/nessus/logs/backend.log
         service: nessus_backend
         source: tenable
   
       - type: file
         path: /opt/nessus/var/nessus/logs/www_server.log
         service: nessus_webserver
         source: tenable
   ```

Customize the `path` and `service` parameter values if necessary for your environment.
