Hi Guys,

I'm monitoring a windows box services with a WMI sensor and would like to get a notification; If state change to UP, then notify.

I've tried to use the "add change trigger" but that doesn't seem to be sending anything when the state of a service changes from Down to UP.

In the State-Triggers I can't select > When sensor is UP........

How can I get this done?

Dear JD Goudsmit

This is not direclty possible with PRTG. However, you can use a down state trigger and then use the "When condition clears" trigger to get notified.

"Condition clears" is not exactly "Up", it means the sensor leaves the state which you defined in the first trigger; but it is close to what you like to do.

Thanks Arne,

Had found that and am now using that. How does one know which services work with 'Add change trigger' ?

Each WMI Service sensor monitors only one service. The service name is part of the sensor name, it can also be reviewed in the settings.

If you create this sensor and check multiple services, PRTG creates one sensor for each service.

Thanks Arne,

Wasn't really what I am after.

How does one know which services work with 'Add change trigger' ?

I've tried this for WMI services on a windows host and that doesn't seem to send an email when the state of a service changes.

Hello

Please open the sensor settings tab. Please enable "If Service is Restarted" / "Trigger 'change' notification".

The sensor should now trigger an according notification.

Hi Arne,

I don't see that option. Only have the option: " If Service is Not Running"...(start/restart service / do nothing)

Dear jdgoudsmit

To enable this setting, "If Service is not Running" "Start/Restart service" has to be selected.

Using this setting, PRTG attempts to start the service which is monitored. If you not wish PRTG restarting the monitored services, the aforementioned option is not avialalbe.

Thanks Arne, Still not seeing it. I've got a wmi service set to "If Service is not Running" "Start/Restart service" in the settings of the sensor, but am not seeing anywhere "If Service is Restarted" / "Trigger 'change' notification".

Which PRTG version do you use?


Mar, 2015 - Permalink

Edition: PRTG Network Monitor Unlimited Version 14.3.10.2422


Mar, 2015 - Permalink

Please update to PRTG 15.1.14. To do this, please either use the autoupdate function, or log into your Paessler webaccount and find the commercial installer download link there.

Please inform me if you can enable the "Trigger 'change' notification" setting in the new version.
