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> <DIV><SPAN class=671420119-07012003><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=671420119-07012003><FONT face=Arial color=#0000ff size=2>Jeff</FONT></SPAN></DIV> <BLOCKQUOTE dir=ltr style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #0000ff 2px solid; MARGIN-RIGHT: 0px"> <DIV></DIV> <DIV class=OutlookMessageHeader lang=en-us dir=ltr align=left><FONT face=Tahoma size=2>-----Original Message-----<BR><B>From:</B> Carroll, Jim P [Contractor] [mailto:jcarro10@sprintspectrum.com] <BR><B>Sent:</B> Tuesday, January 07, 2003 10:41 AM<BR><B>To:</B> Jeff Boulter; Nagios-users@lists.sourceforge.net<BR><B>Subject:</B> RE: [Nagios-users] Setting up service dependencies<BR><BR></FONT></DIV> <DIV><SPAN class=245083718-07012003><FONT face="Comic Sans MS" color=#000080 size=2>I'm not sure why you're taking this approach.

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.
