Parsing Rules requires a Cortex XDR Pro per GB license and a user with Cortex Account Administrator or Instance Administrator permissions.
To help you easily identify and resolve parsing errors in Cortex XDR, all parsing errors are saved to a separate dataset called
parsing_rules_errors. This dataset displays important information about each error, including the RAW_LOG, log metadata, Parsing Rule metadata, and error description, which you need to effectively troubleshoot the problem. In addition, a Parsing Rules Error notification is sent to the Notification Center whenever a new parsing error is added to the dataset.
Types of Parsing Errors
There are different types of parsing errors.
Compilation Errors: Unable to compile a rule for different reasons including invalid function parameters, such as invalid regex.
Data Format Errors: A mismatch between the expected data type, such as CEF, LEEF, or JSON with the actual data, such as TEXT or CSV.
Runtime Errors: Unable to apply a rule to the data, such as an attempt to add a String to a Number.
Parsing Errors Dataset
All parsing errors and Cortex Data Model (XDM) errors are saved to a dataset called
parsing_rules_errors. The following table describes the fields that are available when running a query in XQL Search for the
parsing_rules_errors dataset in alphabetical order.
Some errors can only be found after the applicable logs are collected in Cortex XDR.
