Logs

Overview

This processor adds a field with the name of the host that sent the log. For example, hostname: 613e197f3526. Note: If the hostname already exists, the Worker throws an error and does not overwrite the existing hostname.

Setup

To set up this processor:

  • Define a filter query. Only logs that match the specified filter query are processed. All logs, regardless of whether they do or do not match the filter query, are sent to the next step in the pipeline. See Search Syntax for more information.
