<p class=MsoNormal>Using NRPE_NT running on a Windows server as a WMI Proxy to
process checks on Windows servers via WMI scripts. The initial problem was that
when the proxy was down, or rebooted, we got thousands of alerts from the
services that used the proxy to do checks. We thought that to fix this we would
make all the WMI checks dependent upon the NRPE service running on the proxy. This
way when the parent NRPE service was down or unreachable, the WMI checks would
not be processed. This is NOT working to due the time it takes for the NRPE
service to go from soft-down to hard-down (during this time tons of alerts are
sent out). We enabled soft state dependency and this fixed the problem, but it
will KILL our WMI proxy as its now doing MANY more checks (the NRPE parent
service is constantly checked to get the current state as opposed to using the
last know state, which is what happens when soft state dependencies are turned
off)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So what is the answer to my problem? I need to make sure
that when the NRPE service running on the proxy is down or unreachable, ALL wmi
checks immediately stop and not even a single alert is sent out.<o:p></o:p></p>

<p class=MsoNormal>Thank you<o:p></o:p></p>
