In the NSClient++ documentation, CheckCPU works with normal integers as thresholds (so no %-sign required). As an alternative, you can also check the CPU Utilization with the NSClientListener/check_nt plugin: <a href="http://nsclient.org/nscp/wiki/NSClientListener">http://nsclient.org/nscp/wiki/NSClientListener</a> I use this way of checking the cpu loads/percentages for several hundreds of Windows servers and it works just fine. <div class="gmail_quote">On Mon, Jan 30, 2012 at 12:06 PM, Matthew Jurgens <<a href="mailto:nagiosusers@edcint.co.nz">nagiosusers@edcint.co.nz</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div bgcolor="#FFFFFF" text="#000000"> You might like to try <a href="http://www.edcint.co.nz/checkwmiplus" target="_blank">www.edcint.co.nz/checkwmiplus</a><div class="im"> On 30/01/2012 9:07 PM, Robert Jackson wrote: </div><blockquote type="cite"><div class="im"> <div> Why does the NSClient++ command CheckCPU always sit as a critical condition within Nagios?
