The Cloud DNS metrics dashboard in Google Distributed Cloud (GDC) air-gapped lets you monitor the health and performance of your Managed DNS Zones. Visualization panels display queries per second (QPS), error rates, and 99th-percentile (P99) request latency so that you can identify DNS resolution issues and performance bottlenecks.
This document is for developers in the platform administrator or application operator groups who monitor DNS system health. For more information, see Audiences for GDC air-gapped documentation.
Cloud DNS dashboard
Open the following URL to access the Cloud DNS dashboard:
https://GDC_URL/PROJECT_NAME/grafana/d/cfemcae44701sb/cloud-dns
Replace the following:
GDC_URL: the URL of your organization in GDC.PROJECT_NAME: the name of your project.
The Cloud DNS dashboard presents graphs and visualization panels that contain information about the requests, errors, and latency for your Managed DNS Zones.
QPS per Managed Zone
This panel displays the queries per second (QPS) for each Managed DNS Zone in the selected project. It helps you visualize the rate of total DNS requests being handled by each zone.
Error Rate per Managed Zone
This panel shows the rate of DNS responses that are not NOERROR (successful
resolution) or NXDOMAIN (hostname not found). Monitoring this metric helps you
identify potential issues with DNS resolution, such as misconfigurations or
server problems.
P99 latency per Managed Zone
This panel displays the 99th percentile of DNS request latency. This metric is useful for understanding the performance of your DNS zones and identifying potential bottlenecks that may be impacting request times.
