You can use bar charts in Oracle Logging Analytics to view log records grouped by entities, or log fields.

1. Open the navigation menu and click Observability & Management. Under Logging Analytics, click Log Explorer.
2. Search for logs for a set of entities. See Search Logs by Entities.
3. From the Visualize panel, select Bar ().
4. From the Pinned section of the Fields panel, drag and drop Log Source to the Group by section of the Visualize panel.
   This displays the log records in the form of a bar chart grouped by log sources.

   • You can drag and drop a maximum of two fields from the Fields panel to the Group by section of the Visualize panel.
