Failing event_handlers and ocsp/ochp_command not logged?

[Brian A. Seklecki]

What happens if ocsp/ohcp commands return non-zero status?

# send_nsca -H doesnt.fucking.exist -c foo/etc/nagios/send_nsca.cfg
Invalid host name 'doesnt.fucking.exist'
Error: Could not connect to host doesnt.fucking.exist on port 5667
# echo $?
2

When this happens, its a very serious problem.  Nothing is logged. This
results in a silent failure. 

Obviously, send_nsca should transmit to a hostname in hosts(5) and/or to
an IP address that is highly available resolving any dependency on DNS. 

But even with that in mind, this exec()/fork() model behavior is
pragmatically incorrect.

The code should be checking result code for return values != 0, and
printing a critical error to the logs.

Moreover, even with debug_level=99999999999999999999999999

No warning / error / notice occurs:
