To monitor a custom log file, you, as the Oracle Log Analytics administrator must create a new log source and a parser.
You can create a log source or parser in multiple ways:
From the Oracle Log Analytics Configuration page
From the OMC Navigation icon on the top left corner of the Oracle Log Analytics interface
You can also import source and parser definitions from an XML file. Importing source definitions imports all source-related content such as Extended Fields, Tags, Lookups, and Labels.
To import source or parser definitions, click the gear icon on the top right corner of the Configuration page and select the XML definition file.
