<DIV><FONT face=Arial size=2>Miguel,</FONT></DIV>
<DIV><FONT face=Arial size=2>I don't think you can effectively do EXACTLY what
you want within Nagios.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I understand you correctly and I needed to do
the same I would do one of the following:</FONT></DIV>
<DIV><FONT face=Arial size=2>- I'd then make server1 dependent on server2,
server2 dependent on server1, server 3 dependent on server2, etc. The
behavior might not be exactly what you need but it could suffice.</FONT></DIV>
<DIV><FONT face=Arial size=2>- Create a check_http_cluster service check which
could be a perl script that executes check_http for each host you specify in an
argument and then prints out statistics. This wouldn't be a really complicated
check to write, you'd execute it something like this:</FONT></DIV>
<DIV><FONT face=Arial size=2> ./check_http_cluster --warn1
critical2 1.1.1.1,1.1.1.2,1.1.1.3</FONT></DIV>
<DIV><FONT face=Arial size=2> This would then execute
check_http on 1.1.1.1, 1.1.1.2 and 1.1.1.3 (you could specify many more ip's
too) returning its results to check_http_cluster. The warn1 would give a warning
if there was one or more errors, critical2 would give critical if there were 2
or more errors.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't really think the perl script would be worth
writing so I'd just use dependencies. There might be a better way... but that's
how I'd do it.</FONT></DIV>

<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px"></FONT>
<DIV><FONT face=Arial size=2>I'm not really understanding what you mean by a
virtual service. What I was able to get out of this email was that you want
to define a service such as check_http to check the same "host" multiple
times, for example:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>define service{</FONT></DIV>
<DIV><FONT face=Arial size=2> host_name <A
href="http://www.domain.com">www.domain.com</A><BR>
service_description HTTP check</FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>...but have this issue it's results to more
than one host. If you try and define that service to check host <A
href="http://www.domain.com">www.domain.com</A> twice, you will get an
error. Therefore, you need 2 hosts defined in your hosts.cfg
like:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>define host{<BR> host_name <A
href="http://www.domain.com.internal">www.domain.com.internal</A><BR>
address 127.0.0.1<BR>}</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>
<DIV><FONT face=Arial size=2>define host{<BR> host_name <A
href="http://www.domain.com.virtual">www.domain.com.virtual</A><BR>
address 127.0.0.1<BR>}</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then define a service to check_http for each of
these hosts, and you'll be ok. Just make sure check_http uses the ip address
and not the hostname.</FONT></DIV></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>define service{</FONT></DIV>
<DIV><FONT face=Arial size=2> host_name <A
href="http://www.domain.com.internal">www.domain.com.internal</A><BR>
service_description HTTP check</FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV>
<DIV> </DIV>
<DIV>
<DIV><FONT face=Arial size=2>define service{</FONT></DIV>
<DIV><FONT face=Arial size=2> host_name <A
href="http://www.domain.com.virtual">www.domain.com.virtual</A><BR>
service_description HTTP check</FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Hope this helps!</FONT></DIV>

Services???</DIV>
<DIV><BR></DIV><!-- Converted from text/rtf format -->
<P><FONT face=Arial size=2>Hello,</FONT> </P>
<P><FONT face=Arial size=2>I'm configuring nagios to monitoring a lot of
services. I need to group many services in a "Virtual service" who it is
not associated to a host. For example:</FONT></P>
<P><FONT face=Arial size=2>I have 3 machines with webs servers, so I have
configured 3 independent services associated with it`s respective host.
Now I want to configure a "virtual service" who include those 3 services.
I have been reading all the documentation for nagios and I don`t find how
can I make it. </FONT></P>
<P><FONT face=Arial size=2>My question is: Is it
possible with nagios?</FONT> </P>
<P><FONT face=Arial size=2>Thanks and excuse my poor english.</FONT>
