MetricScopeDimensionsUnits
query_timeglobala dimension per name serverms

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
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
