Invisible alarm for a sensor

Hi,

I would like to monitor 2 devices in cluster for interfaces traffic and other services. as both devices in active/standby mode I see no reason to poll same data for both devices. Therefore, I created a custom sensor to monitor device state (act/stdby). This sensor being tracked by other sensors on the device (interfaces , tunnels ...) with object dependency so in a minute the custom sensor change state to down it triggers the dependent object to PAUSE.

Basically all works great except the fact the normal state of the custom sensor is DOWN (and other dependent object are paused) , I want to make the custom sensor to not trigger any alarm on PRTG, just leave it invisible or hide it somehow.

Is there any way to achieve this ?

Hello, thank you for your post.

A "down" sensor can't be hidden or made invisible, PRTG will always display this down sensor, you can remove notifications from the sensor to avoid notifications but it will be a down sensor.

You could prevent it from going down (if it's a custom sensor) by removing limits for instance, but please note that for the sensor to work correctly as a dependency it must become down/up to achieve it's purpose.

Please consider that it is possible to leverage the HTTP API to pause and resume sensors. It's also possible to create "HTTP Notifications" in PRTG which can pause and resume other sensors.

For further details:

For further details about the API, see PRTG Manual: Custom Sensors.

Best Regards,

Hello again

Thank you Luciano. I basically just want NOT to see this custom sensor in DOWN state in the ALARMS section, as we constantly monitor this view, that's make sense it will be down but thought of an option just not to show it in ALARMS view.

If I create a custom sensor for each pair of devices I will end up with dozens of sensors being marked as DOWN and visible on ALARMS view which monitoring dept. can think its a fault, which it doesn't.

Thanks

Hello ND30,
thank you for your reply.

Well, if you're concerned with the Alarms view consider the following:

The "Alarms" view is basically the following view/filter:

/alarms.htm?filter_status=5&filter_status=4&filter_status=10&filter_status=13&filter_status=14

You can add the following to the URL to filter out a single tag from the "Alarms" view:

&[email protected](-mycustomtag)

This means, the following URL will bring you the Alarms list but exclude sensors with a specific tag:

/alarms.htm?filter_status=5&filter_status=4&filter_status=10&filter_status=13&filter_status=14&[email protected](-pingsensor)



The sensors can't be "down" without being down and this is the only way to trigger dependencies. One other approach I can think of is adding your monitoring dept. to a specific user group and removing the Access Rights from the sensor you don't want them to see, this should make it "invisible" in all views from those accounts/user group.

For further details: PRTG Manual: User Access Rights

Best Regards,
