dns

Tracks incoming and outgoing DNS traffic, providing various metrics and details about the DNS queries and responses.

Architecture​

This plugin uses Inspektor Gadget's DNS Tracer to track DNS traffic and generate basic metrics derived from the captured events.

In Advanced mode, the plugin further processes the capture results into an enriched Flow with additional Pod information. Subsequently, the Flow is transmitted to an external channel. This allows a DNS module to generate additional Pod-Level metrics.
