you want varnishncsa:

varnishncsa -q 'ReqURL eq "/whatever/url/you/want"' -F "%{User-agent}i"

this will give you real-time output, it you just want to see whatever you have in the backlog, add -d:

varnishncsa -q 'ReqURL eq "/whatever/url/you/want"' -F "%{User-agent}i" -d

In doubt, man varnishncsa, it has all the info about the format string, and you can look at man vsl and man vsl-query for mor info about the -q argument.
