[hobbit] How hobbit server deal with DNS server failure when doing conn test ?
Neither. It tries DNS, then it tries the IP address in the bb-hosts file. If it can ping the IP address it sets the conn dot to green. The only place I have found that reports it could not resolve the name via DNS is in the output I copied into my email.

So if it can not resolve DNS, is it yellow instead of red?

Josh,
I think the first statement is true. I have many items monitored by hobbit which are not registered in DNS (I live with a bunch of windows centric team mates and they rely on WINS not DNS. None of these items end up with conn=red, but they are ID'd in the output from bbtest on the hobbit server. Here is that output:
DNS statistics:
hostnames resolved : 383
succesful : 306
failed : 77
calls to dnsresolve : 414
Notice that I have 77 monitored items which fail the DNS lookup.

Pretty confident if the DNS lookup fails it times out and marks the conn red =( If you don't need it to do a DNS lookup simply add testip.

found the manpage.

but still not sure about ping test. will ping(conn) test will do the same like testing of telnet,http type of services.
--dns=[ip|only|standard] Determines how bbtest-net finds the IP adresses of the hosts to test. By default (the "standard"), bbtest-net does a DNS lookup of the hostname to determine the IP address, unless the host has the "testip" tag, or the DNS lookup fails.
With "--dns=only" bbtest-net will ONLY do the DNS lookup; it it fails, then all services on that host will be reported as being down.
With "--dns=ip" bbtest-net will never do a DNS lookup; it will use the IP adresse specified in bb-hosts for the tests. Thus, this setting is equivalent to having the "testip" tag on all hosts. Note that http tests will ignore this setting and still perform a DNS lookup for the hostname given in the URL; see the "bbtest-net tags for HTTP tests" section in bb-hosts(5)

First answer was correct. It will try DNS and if it can't resolve it, it will use the IP and all will be green. I have many hosts with no DNS entries (such as switches) and they don't fail when they have no DNS entry.
