Log Sources define where the log files are located when you use management agent for collection, and how to parse and enrich the logs while ingesting them, irrespective of the method of ingestion. Oracle Logging Analytics has hundreds of sources for database, applications, and infrastructure of both Oracle origin and non-Oracle origin. See Oracle-defined Sources.

You can customize the Oracle-defined content by adding your own elements to them. When Oracle updates the Oracle-defined sources, you will continue to get those updates while at the same time keeping your customizations.

If you don't find an Oracle-defined source that suits your requirement, then you can create your own. When creating a source, you will need to pick one or more parsers to parse the log file into log entries and to break the log entry into fields. You can create a custom source and use an Oracle-defined parser if there is already one that matches your log format. If there is no Oracle-defined parser for your custom source, you can create a custom parser as well. See Create a Parser.

You can also use this if you want to store a copy of your definitions outside of Oracle Logging Analytics. See Import and Export Configuration Content.

• View in Log Explorer: The Log Explorer opens. The displayed logs are filtered for this source.

• Delete: You may have to delete some of your old or unused sources to conform to the service limits of Logging Analytics. See Limits by Service in Oracle Cloud Infrastructure Documentation.
