Nothing to worry about in this case. Since you're not running the
command from a shell, NOTTY is expected.

This is an interesting bit. The plugin is a perl program. Nagios loaded
it and would have been ready to execute it. Perl plugins could possibly
be treated 'specially' and have special requirements if you compile
Nagios with the embedded perl interpreter (ePN) enabled. Did you do so?
In the command{} definition for check_logs.pl, try disabling the use of
ePN by prefacing the command with your /path/to/perl --

(from memory)
define command {
command_name   check_logs ; or whatever it is
command_line   /path/to/perl $USER1$/check_logs.pl (... other stuff
here)
}
