<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there any way to make check_http fallback on dns service
used (like other services at the machine)?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>A little test reveals that apparently only the primary DNS
server is in use, the second and following name servers are ignored.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>--<o:p></o:p></p>

-H <hostname> -u / -f warning -p 80 -w 3 -c 5 -t 10<o:p></o:p></p>

<p class=MsoNormal>--<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I know there is a “-I” parameter for
passing in the ip directly to the check, but this is not the behavior I’m
after - I still want the check to be dynamic with regards to the IP address for
the service.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I hope I’m just missing the obvious?<o:p></o:p></p>
