+With **Logs Explorer**, based on Discover, you can quickly search and filter your log data, get information about the structure of log fields, and display your findings in a visualization.
+You can also customize and save your searches and place them on a dashboard.
+Instead of having to log into different servers, change directories, and view individual files, all your logs are available in a single view.
+
+Go to Logs Explorer by opening **Discover** from the navigation menu, and selecting the **Logs Explorer** tab.
