Remote Icinga Instance Connection Issues – Troubleshooting

I have ran into the same problem. It turns out that following directory has no read permission for other group:

# ls -ld /usr/local/libexec/nagios/
drwxr-x---  2 root  wheel  1536 May 28 15:20 /usr/local/libexec/nagios/

The reason for that was because I have set a stricter umask in my ~/.cshrc:

# cat ~/.cshrc
umask 27

Change the permission of the directory solving the problem:

# chmod 755 /usr/local/libexec/nagios/

Verify all the nagios plugins have the read permission as well:

# ls -l /usr/local/libexec/nagios

For starters you can designate each site with a particular port 8080, 8081, etc. and then use something like autossh to maintain the connections. Then you'd be connected and would just need to go from 8080 to 8081 check each site that you've mapped to a designed local port.

This type of approach could be scaled up so that instead of you looking at each sites' local port, you could have a script do the checking instead. Depending on what's on each site' Icinga site, you could periodically check it with your own Nagios/Icinga site that's been configured to check for the various things you've been checking for manually.

It's really hard to provide more info without more specifics.
