wrong results while using check_nt<BR><BR></FONT></FONT></DIV>
<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>

<P><FONT face=Arial size=2>I am having problem in monitoring a particular
windows perfmon counter. All other counter gives proper results. I am using
check_nt (check_nt (nagios-plugins 1.4.3) 1.39) with Nagios Agent running on
WIndows NT 4.0, Exchange 5.5</FONT></P>
<P><FONT face=Arial size=2>Below is the Microsoft Exchange counter:</FONT>
<BR><FONT face=Arial size=2>Object: MSExchangeMTA Connections</FONT>
<BR><FONT face=Arial size=2>Counter: Queue Length</FONT> <BR><FONT
face=Arial size=2>Instance: (INTERNET MAIL CONNECTOR (MAILHOST001))</FONT>
</P>
<P><FONT face=Arial size=2>When I run the plugin command mannualy I
get,</FONT> </P>
<P><FONT face=Arial size=2>./check_nt -s nagiosagentpassword -H mailhost001
-v COUNTER -l "\MSExchangeMTA Connections(INTERNET MAIL CONNECTOR
(MAILHOST001))\Queue Length"</FONT></P>
<P><FONT face=Arial size=2>0.000000</FONT> </P>
<P><FONT face=Arial size=2>and output is always 0.</FONT> <BR><FONT
face=Arial size=2>But if I use windows perfmon, I get the proper
results.</FONT> </P>
<P><FONT face=Arial size=2>Any idea why this is not working?</FONT> </P>
