Syntax: show gslb dns detail [<name>]
This command’s output is enhanced to show the following information:
• The metrics that were used to select a given site as the best site.
• For each of the GSLB metrics that have been used to select the site, the number of times that
metric was the deciding factor in selection of the site.
The metric statistics are displayed under the Metric counter line. In this example, site 1.1.1.101 has
been selected as the best site a total of eight times. This is shown in the DNS resp. selection
counters column. The health-check metric was used once to select site, the round robin selection
metric was used three times to select the site, and the least-response metric was used four times
to select the site.
If the site has not been selected yet as the best site, the line under Metric counter says "Not
selected yet".
