NotificationTrigger Deserialization issues w/SNMP Custom Sensors

[pyro3d]

Describe the bug Clearly and concisely describe what you were trying to do, what happened and what you were expecting to happen Getting notification triggers on a SNMP Custom Sensor results in deserialization errors.

Steps to reproduce Put the relevant code from your application that caused the issue to happen in the code block below

PS /Users/%snip%> Get-Device "*EX2300-%snip%*" | Get-Sensor "Status" | Get-Trigger -Type Threshold
Get-Trigger : Could not deserialize channel 'RE Temperature' of threshold trigger '1' of object ID '47108'. Object may be in a corrupted state. Please check the notification triggers of object ID 47108 in the PRTG UI.

+ CategoryInfo          : NotSpecified: (:) [Get-NotificationTrigger], InvalidStateException

What is the output of Get-PrtgClient -Diagnostic?

PS /Users/%snip%> Get-PrtgClient -Diagnostic

Hi @pyro3d,

Are you able to run the following commands and provide the output?

Set-PrtgClient -LogLevel All
Get-Device "*EX2300-%snip%*" | Get-Sensor "Status" | Get-Channel
Get-Device "*EX2300-%snip%*" | Get-Sensor "Status" | Get-Trigger -Type Threshold -Verbose

Please remove any sensitive information (e.g. server, username and passhash) from the response before posting it

I had forgotten to include the -Verbose parameter in my original reply. The last command should be

Get-Device "*EX2300-%snip%*" | Get-Sensor "Status" | Get-Trigger -Type Threshold -Verbose

[pyro3d]

Saw your update just after I replied. :)

I have a very strong suspicion the issue is that you're running PRTG 20.1.57.1745

This

https://%snip%/api/table.xml?content=objects&columns=objid,name,parentid,tags,type,active,basetype&count=*&filter_objid=47108&username=%snip%&passhash=%snip%

<?xml version="1.0" encoding="UTF-8"?>
<objects totalcount="0" listend="1">
<prtg-version>20.1.57.1745</prtg-version>
</objects>

Should return something. There was an issue (#143 ) detected with PRTG 20.1.57.1745 where filtering by ID does not work anymore. Can you please update to 20.1.57.1786 and advise how it goes?

[pyro3d]

I'll get a MW together and update. Hopefully should be this week. Thanks for the catch!

[pyro3d]

Updated PRTG and that was the issue! Thanks for the help @lordmilko!
