looked at the examples that come with nagios and they don't seem to address the

examples using hostgroups, I'd love to see them.</FONT></SPAN></DIV>

up. Okay, I can see that.</FONT></SPAN></DIV>

<DIV><SPAN class=671420119-07012003><FONT face=Arial color=#0000ff
size=2>That's good to know. I still have this issue though because I have
some tests that aren't going work if simpler tests fail. For example, a
simple test to see if a webserver can serve a static HTML can fail, and if
that's the case then checking to see if the webserver will return a PHP page
is obviously not going to work. </FONT></SPAN></DIV>

made. If the host check fails, it's flagged as down and, depending
on your particular configuration, you'll receive the notification for the
host being down, not for the N services you're monitoring on that
host. If the host check passes, then you'll get an alert on the
service.</FONT></SPAN></DIV>

Setting up service dependencies<BR><BR></FONT></DIV><!-- Converted from text/rtf format --><BR>
<P><FONT face=Arial size=2>Hello all,</FONT> </P>
<P><FONT face=Arial size=2>I'm trying to set up service dependencies in
Nagios. For example, I don't want alerts about an HTTP service being
down on a host if the host isn't pingable.</FONT></P>
<P><FONT face=Arial size=2>So far, the only way I've found to do this is
to set it up for each host individually. That would be difficult with
the hundreds of hosts that my nagios is currently monitoring.</FONT></P>
<P><FONT face=Arial size=2>I tried creating a servicedependency object
with a hostgroup_name and a dependent_hostgroup_name. This seems to make
each host in hostgroup_name dependent on EVERY host in
dependent_hostgroup_name. For example, if my hostgroup has 7 hosts in
it, it seems it's making each of those 7 hosts dependent on each other,
making 7x7=49 dependencies. (Stragely, Nagios reports 98 dependencies.
Why 2x?) </FONT></P>
<P><FONT face=Arial size=2>Any suggestions on how to make a service
dependencies local to each host and not a group of hosts without lots
and lots of dependency objects?</FONT></P>
