[hobbit] How hobbit server deal with DNS server failure when doing conn test ?

[White, Bruce]

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.

I remember somewhere in the manpages,

The hobbit server when doing fping conn test, it will try using FQDN and if
not resolvable,
it will use the ip address(from bb-hosts) file.

Is this a correct statement ?

I will summarize the answer here
