/usr/libexec, and /usr/local/libexec is the quick answer to your 
question, but how useful that information will be depends on more 
information. If you could provide the following details, it would be 
very helpful:

- output of command "uname -a"
- Nagios version
- exact name of the plugin you're having problems with
     From the errors you posted already, there may be some confusion - 
check_mrtggraf doesn't use snmp directly, it uses the information 
collected by a separate program called MRTG (which must be installed, 
configured and running properly in order to generate the log file 
check_mrtggraf currently can't find). And, there are many snmp plugins.
- Nagios command definition for the plugin
- Nagios service definition for the service calling this command.

As Giles says, you really do need to have some understanding of the OS 
you're running Nagios on. Different OS's can install different bits of 
Nagios in different places, for one thing.
