Also.. this is the only thing logged in apache's access_log.. error_log
remains quiet..

no error so I assume it posted it ok? Any ideas on how to actually
troubleshoot why this is broken?

Does your Apache server run under username 'www'?  (It appears that way,
because you have a 'www' as a member of the 'nagiocmd' group.)

Excellent thanks. Did everything in there and it still doesn't work.. sigh..
Yes I did restart apache after making the changes.. The message is different
now though:
 
Error: Could not stat() command file '/usr/local/nagios/var/rw/nagios.cmd'!
The external command file may be missing, Nagios may not be running, and/or
Nagios may not be checking external commands. 
An error occurred while attempting to commit your command for processing.
 
So lets see.. 
 
#1-nagios is running (even stopped and started it in case anything needed to
be reread).
 
[root at PS-NAT var]# ps auxw | grep nag
nagios     10021  0.1  0.2  2092 1100 ?   S   14:40   0:00
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
 
#2-the external command file is apparently there (created when nagios starts
up)
 
[root at PS-NAT var]# ls -l rw/
total 0
prw-rw----    1 nagios   nagiocmd        0 Nov 14 14:36 nagios.cmd
 
#3-Nagios is set to check external commands
 
[root at PS-NAT var]# cat ../etc/nagios.cfg | grep check_ext
check_external_commands=1
 
other output?..
 
[root at PS-NAT var]# cat ../etc/nagios.cfg | grep command_file
command_file=/usr/local/nagios/var/rw/nagios.cmd
 
[root at PS-NAT var]# ls -l

External Command File Permissions 
http://nagios.sourceforge.net/docs/1_0/commandfile.html
<http://nagios.sourceforge.net/docs/1_0/commandfile.html>  
I think this is the page you were looking for as I looked for it for a week.
Not sure why it didn't ship w/ the documentation... Or maybe I just didn't
find _that_ either.

 When I try to click on "disable monitoring of this service" to not monitor 
 one I get this page: 
  
 Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd'
for 
 update! 
 The permissions on the external command file and/or directory may be 
 incorrect. Read the FAQs on how to setup proper permissions. 
 An error occurred while attempting to commit your command for processing. 
  
  
 Now I know I read some spot in the docs on how to configure this but I
can't 
 find it now. Can't find it in the online FAQ either. Ideally I'd like it so

 anyone can view the status of the page but only those I've created admin 
 accounts for can schedule downtime and enable/disable service checks (i.e. 
 modify nagios through the GUI). I apologize in advance for even asking this

 question as I know it's asked all the time. Just point me to the right page

 please :-)
