Chapter 7: Wired Analysis
177
When you set up a User Test you may enter a URL (the common
name of a web site) such as www.google.com to specify the user
test’s target.
When the user test runs, a DNS lookup is performed to resolve the
target’s IP address. This IP address will appear on the HOST tab
(and on the ALL tab) of the Wired Analysis results.
The analyzer performs a reverse DNS lookup on the resolved IP
address. The resulting name may be different from the URL you
entered in the User Test setup because some entities have
multiple DNS names. For example, the reverse DNS lookup may
produce a name such as dfw06s03-in-f18.1e100.net rather than
google.com.
To find the Wired Analysis results for a user test’s target server,
you may need to search for it in the Wired Analysis results by its IP
address, as follows.
1
Ensure that AutoTest has been run.
2
Tap the user test’s icon on the HOME screen. The user test’s
RESULTS tab is displayed.
3
Scroll to the bottom of the screen to view the IP address of
the user test’s target server.
4
Now return to the wired analysis results, sort by IP address,
and find the user test’s target server.
5
If the user test does not complete successfully, its target server
may not be displayed in the wired analysis results.
