DNS resolution time

The "DNS" metric corresponds to the time needed to perform the DNS resolution process when the HTTP-Tracer target contains a domain name.

This metric is available in different dashboards.
First, it is provided on maps.

It is also provided in different tables in the dashboards "Network Overview", "Performance by Tester" and "Performance by Target". Activating the "sparkline" option allows you to see the evolution over time, right from the table:

Finally, the "Web performance" dashboard provides the evolution over time of this metric, as well as the distribution graph.

Important note:
When redirections occur, the DNS time value corresponds to the sum of all DNS times measured for each redirection, up to the final destination.
