A specialized node that performs additional operations alongside a LogScale cluster without handling standard ingestion, storage, or query processing. Auxiliary nodes extend cluster functionality by providing services such as PDF report rendering, or other supplementary processing tasks. These nodes connect to the LogScale cluster through specific endpoint URLs and are monitored through the Auxiliary services interface in the system administration panel. Each auxiliary node has a service type, version, and status that administrators can track. Examples include the pdf-render-service for generating scheduled PDF reports from dashboards.
