Yepp, i run the same checks against 3 other boxes, same OS, same config everything (cloned) - i get OK status from them. The input i get from the troubled box do not contain any strange chars or trails. If i submit a passive OK result (using the string i get) it resets to OK status. But at next automatic check it will be set to UNKOWN again .. /Fredrik <div class="gmail_quote">On Tue, Feb 24, 2009 at 5:00 PM, John Drescher <<a href="mailto:drescherjm@gmail.com">drescherjm@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="Ih2E3d">On Tue, Feb 24, 2009 at 10:49 AM, Fredrik Stridfeldt <<a href="mailto:stridfeldt@gmail.com">stridfeldt@gmail.com</a>> wrote: > Hi, > > Yes $? eq 0 on both sides. > > From appserver: > libexec/check_disk -w 400 -c 220 -p / > DISK OK - free space: / 13998 MB (82%);| /=3149MB;16747;16927;0;17147 > bash-2.05$ echo $? > 0 > > From Nagiosbox: > -bash-3.2$ /usr/local/nagios/libexec/check_by_ssh -H 10.194.145.142 -t 60 -l > "nagios" -C "libexec/check_disk -w 400 -c 220 -p /" > DISK OK - free space: / 13998 MB (82%);| /=3149MB;16747;16927;0;17147 > -bash-3.2$ echo $? > 0 > </div>Are you sure the path to the plugins is correct on both sides? In gentoo I have had this error when the distro decided to change the default location of the plugins.
