I have several counters that are being monitored on the client including CPU Load, Disk Usage, Memory Usage, Server Uptime, and Paging File Usage. All counters except Paging File Usage appear to be running without issue. The error message that I am seeing with Paging File Usage is the following: NSClient - ERROR INVALID COUNTER - PagingFile(_Total)% Usage - ERROR CODE: 0xC0000BB8 - I have a Windows 2003 R2 64-bit server that is being monitored with the same counters, and the Paging File Usage counter does not return an error. The syntax for the command in question, taken from the commands.cfg file, is shown below: # 'check_nt_pagingfile' command define command{ command_name check_nt_pagingfile command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 5667 -v COUNTER -l "<A HREF="file://\\PagingFile(_Total)\\%">\\PagingFile(_Total)\\%</A> Usage","Paging Fileusage is %.2f%%" -w $ARG1$ -c $ARG2$ } Does anyone know what change(s) are needed to the above command, assuming it can still be used, in order for it to accurately keep track of the paging file in the Windows 2008 server?
