StackState-PowerDNS Integration

Overview

Connect your PowerDNS Recursor to StackState to:

  • Visualize its performance
  • Understand query latency
  • Get alerted when something fails or when you’re under attack

Setup

Configuration

Configure the Agent to connect to the PowerDNS Recursor. Edit conf.d/powerdns_recursor.yaml :

init_config:

instances:
  - host: 127.0.0.1
    port: 8082
    api_key: pdns_api_key

Validation

  1. Restart the Agent
  2. Execute the info command and verify that the integration check has passed. The output of the command should contain a section similar to the following:
