 | ------------ | ----------------------------------------------- | ------- |
-| Interval_Sec | Polling interval in seconds                     | 1       |
-| Include      | A space-separated list of containers to include |         |
-| Exclude      | A space-separated list of containers to exclude |         |
-| Threaded | Indicates whether to run this input in its own [thread](../../administration/multithreading.md#inputs). | `false` |
-| path.containers | Used to specify the container directory if Docker is configured with a custom "data-root" directory. | `/var/lib/docker/containers` |
+| `Interval_Sec` | Polling interval in seconds                     | `1`   |
