Is it possible, based on a certain sensor treshold or state (down/up) to trigger an output on any, but for instance above mentioned device?

We need to trigger several inputs (non IP) so we want to connect a IP based output unit (several outputs) so we can trigger those.

Any idea on how to configure this? And how to only trigger a specific output?

Hi,
we have not tested this so I cannot guarantee if this will work but you might have a look at the EXE Notifications. Those can be used to trigger a script on a certain sensor state, so if you are able to access the device using a script you might give this a try.

I'm going to contact Axis if their unit (P8221) supports it, or what it supports else...

Get back here after that.

They Say it is possible using a "HTTP" request, is that possible with PRTG?

Other thing that popped my mind is: can PRTG send SNMP traps maybe?

Hi there,

You can create Notifications and choose

  • Execute HTTP Action
  • Send SNMP Trap

Afterwards, you can add a state trigger to the device or sensor to send the HTTP request or SNMP Trap.

Hi,

I figured out to do a http trigger on the device and the Output did indeed get triggered.

However when i try it from PRTG nothing happens.

In the log of the device we get a "unauthorized" message, could make sense that i need to add the user credentials for the I/O unit in PRTG, been searching but i can't figure out where!

I need to create around 60 http sensors with the unique strings to trigger all the Outputs on several devices.

Thank you and kind regars.

Hi,

You can add Postdata to the HTTP POST in the settings of the notifications. If this is not accepted by the target device, you will need to create a custom script which is triggered by the notification. You can create a notification with Execute Program.

Yes i saw that, but i don't have any clue to know "how" to put the credentials in there.

I have a running case with Axis, but it was very difficult to get the string for triggering the output via http, i doubt if i ever get the info like this......

Do you have any experience with that, like some "common practise"?

Hi,

I'm afraid that we do not have these devices in our test environment and it depends on the API of the Axis device, so I cannot assist you in this case, sorry.

In PRTG, the credentials are simply appended to the URL:

/api/getsensordetails.xml?id=sensorid&username=name&password=pass

Best regards

Well, scratch that! They do have that information and they shared it with me.

I have it all working now, i can trigger the output and turn it off after a predefined amount of time using a single URL.

So let me share it here:

In order to open an output contact (nr 1):

http://uname:password@mydeviceIP/axis-cgi/io/port.cgi?action=1:/

In order to close an output contact (nr 1):

http://uname:password@mydeviceIP/axis-cgi/io/port.cgi?action=1:\

In order to open and close (2 seconds) a contact (nr 1):

http://uname:password@mydeviceIP/axis-cgi/io/port.cgi?action=1:/2000\

The url for opening a contact without username and password:

http://mydeviceIP/axis-cgi/io/port.cgi?action=1:/

Thanks for sharing the solution with the community! Good to hear that it's working now.
