When trying to execute a nagios plugin, you’re getting this error:
# /usr/lib/nagios/plugins/check_procs bash: /usr/lib/nagios/plugins/check_procs: No such file or directory
But when checking further, the file does exist:
# ls -l /usr/lib/nagios/plugins/check_procs -rwxr-xr-x 1 root root 124929 Jan 19 2016 /usr/lib/nagios/plugins/check_procs
This can be due to some 32 bit libc libraries missing. To fix that, you will have to install the 32-bit shared libraries for AMD64 by installing this package:
libc6-i386
And now, you can try again, error should have gone away!
# /usr/lib/nagios/plugins/check_procs PROCS OK: 152 processes|procs=152;-1;-1;0
