Yes, the search path for executables. In other words, perhaps neither 
/usr/local/bin nor /opt/tools/pipesend are used to search for programs.

The PATH is, usually and IIRC, set in the start script for nagios or 
inherited from the existing environment.

The most useful thing you might do is simply use all commands with a 
full path - that avoids some security holes as well.
