Parser Errors

When a parser fails to parse incoming input, LogScale automatically adds the following fields to the event:

  • @error=true

  • @event_parsed=false

  • @error_msg: contains the error message

You can search for these fields to determine what happened and update the parser accordingly. When you find an error, you can add the @rawstring of any events that fail to parse as a test case for your parser.

Finding Errors

You can search for all events that were not parsed correctly by searching the repository:


You can extend the query in different ways. For example, you can display a timechart:

@error=* | timechart()

or group results by error message:

@error=* | groupBy(@error_msg)

The original log input is available in @rawstring.


There is no way for LogScale to re-parse data once it's stored, even if there is an error on the event. You'll have to resend the event through the ingest API.
