think I found a workaround for this. For some servers, like webservers most of
the services are some form of HTTP request, so I changed the check_command on
the host to do a simple http request. If that fails, then the host is considered
'down' rather than just using the standard ping check. If this is 'bad' for some
reason, please let me know.</FONT></SPAN></DIV>

question: is it possible to pass arbitrary ssh parameters to check_ssh,
like "-1" for ssh v1? Doesn't appear so, but maybe there's a
trick?</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>

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>
