# View Log Data

The Log Viewer is where you can view all your logs, filter data, and create custom views.

When opening the [Log Viewer](https://app.logdna.com/logs/view) for the first time, you'll see all your logs for any apps or hosts added.

## Views

Any Views you create will appear here. Use Views to narrow down the data you want to see. Learn more in [Create and Edit Views](https://docs.mezmo.com/2.8/docs/create-and-edit-views).
