Maybe you include another file in which the command check_all_disk is defined a second time? That would be a simple explanation... What happens if you add a sudoers entry to allow the nagios user (or the user you're running the nrpe daemon as) to launch check_disk? Modify the check_command so you use sudo before the check_disk command. </div> <div class="gmail_quote">On Mon, Mar 12, 2012 at 6:32 PM, davor grgicevic <<a href="mailto:dgrgicevic@gmail.com">dgrgicevic@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi Timothy localy u r workiong as root.. if you try as user Nagios, it wont work .. u have to run sudo for this <div class="im"> "DISK CRITICAL - /dev/pts is not accessible: Permission denied" </div>davor On Mon, Mar 12, 2012 at 6:17 PM, Boyer, Timothy A. <div><div></div><div class="h5"><<a href="mailto:Timothy.Boyer@opm.gov">Timothy.Boyer@opm.gov</a>> wrote: > $ ./check_disk -w 10% -c 5% -p /sys > > DISK UNKNOWN - free space:| > > > > is the result on both servers. > > > > But that’s running locally, which works.
