dnsquery

DNS query collector

This module provides DNS query round-trip time (RTT).

Metrics

All metrics have "dns_query." prefix.

Labels per scope:

• server: server, network, record_type.

Configuration

Edit the go.d/dns_query.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/dns_query.conf

Here is an example:

jobs:
  - name: job1
    record_types:
      - A
      - AAAA
    domains:
      - google.com
      - github.com
      - reddit.com
    servers:
      - 8.8.8.8
      - 8.8.4.4

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the dns_query collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/
  

• Switch to the netdata user.

  sudo -u netdata -s
  

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m dns_query
