createParser()

API Stability	`Deprecated`

The createParser() GraphQL mutation may be used to create a parser in LogScale. However, this has been deprecated and will be removed in version 183.142. It has been replaced by mutation where more extensive test cases can be set. Use instead createParserV2().

For more information on creating a parser, see the Creating a Parser documentation page. You may also want to look at the Parsing Data and Parsing Log Data pages for related information.
