The "check_disk" plugin describes the "-L" (--stat-remote-fs) option as providing this functionality. However, either I'm not understanding how the option works, or it's not working properly. Here is an example of what I'm seeing: <blockquote> <blockquote><tt># df -h /usr/local</tt> <tt>Filesystem Size Used Avail Use% Mounted on</tt> <tt>oxygennfs48:/usr/local 250G 214G 37G 86% /usr/local</tt> <tt>#</tt> <tt># ./check_disk -w 20% -c 10% -p /usr/local</tt> <tt>DISK WARNING - free space: /usr/local 37846 MB (14% inode=98%);| /usr/local=218154MB;204800;230400;0;256000</tt> <tt>#</tt> <tt># ./check_disk -w 20% -c 10% -p /usr/local -L</tt> <tt>DISK UNKNOWN - free space:|</tt> <tt>#</tt> </blockquote> </blockquote> Does anyone have any experience using this option, or have any guesses why it's generating an error? <pre class="moz-signature" cols="72">-- David Wallis Principal Computer Engineer Information Technology Group Advanced Photon Source Argonne National Laboratory </pre> </body> </html>
