Aha! Ok, thanks.

I made the mistake of running that manually, and it kind of short circuited every CONN test out there on the running server. Oops. More pager batteries........................

Hi- by the way, my cluster stuff is finally working the way I want. Thanks for putting up with my ignorance on how the hobbitd and bbproxy stuff co-exist (or don't)!

In my bbtests column of my main server, I see:

DNS statistics:

hostnames resolved : 141

succesful : 136

failed : 5

calls to dnsresolve : 183

.... any idea what's the easiest way for me to discern "which" of my 183 hosts are failing DNS resolution?

The only way currently is to run bbtest-net with the --debug option, and grep the output for "DNS lookup failed". I've been asked before, so I really should add some way of easily finding this information, or at least provide a way of logging it.

BTW, you don't have 183 hostnames - you have 141. The 183 is the number of times a hostname lookup was done, so some of them was via the cache that bbtest-net has. This is because the same hostname may be needed for multiple tests, e.g. if you use it in http url's that you test.
