Stupid sound question - "DNS Error"

Try increasing the timeout setting on the network tests - add a
"--timeout=30" option to the bbtest-net command in hobbitlaunch.cfg .

It seems adding a local caching DNS server did no fix this problem.  I'm
truely at a loss now, because nothing I test manually seems to indicate a
problem.  Also, when the hobbit alerts go red due to "DNS Error", as soon as
I go to check, it has cleared up already.

It sounds like an obvious answer, but what does the http/https

error "DNS Error" mean, exactly?

It means Hobbit could not lookup the hostname in DNS.

Okay, I thought it was pretty self explanatory, but a quick glance at the
code wasn't obvious to me.

Specifically, I have several https checks defined in Hobbit, and a good

number of them get the "DNS Error" message multiple times a day;
roughly on
the order of every 1-3 hours.  I have manually verified that DNS is
working
for these hosts.  It might help me troubleshoot this if I know exactly
how
Hobbit comes to this determination, and if anything else other than

DNS

could cause it to appear.

A local caching DNS server is usually a good idea. Hobbit has been known

to knock out DNS servers, because it sends a lot of requests very
quickly.

Well, two suggestions to have a local caching DNS must mean it's a pretty
good idea.  I set this up, and will see if that fixes the problem.
