    I’ve installed Nagios 4.0.8 on CentOS 6.6 and keep getting these error messages on certain checks:

    (No output on stdout) stderr: Can’t locate Nagios/Plugin/ in @INC (@INC contains: /usr/local/nagios/libexec/lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .)

    (No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_nrpe, …) failed. errno is 2: No such file or directory

    Any suggestions?

    • Ravi Saive says:
