<div>Hi,</div> <div> </div> <div>If your windows agent is NC_NEt, I know the reason why,</div> <div>It has to do with delay between taking samples of the performance counter object before reporting it to back to check_nt</div> <div> </div> <div>To elaborate, most Performance monitor objects in windows takes a sample every one second then return the caalculated results to Performance monitor for graphing. </div> <div> </div> <div>NC_NEt does not wait a full second for this to happen, and in the current inplementation it is actually too quick between samples and thus gives a result of 0.</div> <div>I have experimented with different delay times (in Miliseconds) and found a good speed/accuraccy compromise that I will implement as adjustable variable in the configuration of the next release of NC_NEt. </div> <div>Note: NC_NEt would report a -1 if the it could not locate the counter because of an error or spelling.</div> <div>but a 0 means really 0 or the above mentioned bug.</div> <div> </div> <div>Just to defend NC_NEt. in the past, this bug slipped through due to the Performance counter documentation of Dot NEt specifying just to call the get sample function again, and the documentation failed to mention any standards as to a minimum delay between requests. Also most of NC_NEt testing in the past has been done offline of Nagios. I am about to install nagios for testing, and hopefully would have that running by the time I get the updates into NC_Net. </div> <div> </div> <div>As a workaround you may be able to retrieve the value you need through WMI</div> <div> or by creating a custom performance counter that is of a different type but gets its value from the one that is mis-informing NC_NEt.</div> <div> </div> <div>NC_NEt is availible at sourceforge: <a href="http://sourceforge.net/projects/nc-net">http://sourceforge.net/projects/nc-net</a></div> <div> </div> <div>If it was a different Windows Client then I do not know the source of the reason but next generation of NC_Net should work more efficiently.</div> <div>Thank you </div> <div> </div> <div>TOny (Author of NC_NEt)<br> </div> <div><span class="gmail_quote">On 12/5/06, <b class="gmail_sendername">M V Ajay (vMoksha)</b> <<a href="mailto:Ajay.MV@ucb-group.com">Ajay.MV@ucb-group.com</a>> wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div> <p><font face="Arial" size="2">Dear All:</font> </p> <p><font face="Arial" size="2">I am having problem in monitoring a particular windows perfmon counter.
