Performance Monitoring

To understand and optimize the performance of DNS-collector, you should enable telemetry. Telemetry allows you to monitor the internal pipeline traffic, detect bottlenecks, and see if any packets are being discarded.

Why Enable Telemetry?

By enabling the process telemetry, you gain real-time visibility into: - Ingress and egress message rates per pipeline worker. - Dropped and discarded message counts (crucial for buffer sizing). - System resource usage (CPU, memory allocations, goroutines count).

How to Enable Telemetry

Enable telemetry in the global section of your configuration:

global:
  telemetry:
    enabled: true
    web-listen: ":9165"
    web-path: "/metrics"
    prometheus-prefix: "dnscollector"
