Get-Group -ParentID 1 | Lists to wrong Groups

Describe the bug

We have the Core Server Object (Probe, with ID 1). In there is 1 Group with 1 Device. In there are some Sensors.

Our Script is calling the Function: get-Group -ParentID x This works with the Probe ID of e.g. “15193”. But it doesn’t work for the ID 1 (Core).

My result of my this code line includes 263 PRTG Groups. Expected is 1 PRTG Group.

Steps to reproduce

get-group -ParentID 1

What is the output of ‘Get-PrtgClient -Diagnostic’?

PSVersion      : 5.1.19041.1237
PSEdition      : Desktop
OS             : Microsoft Windows 10 Pro
PrtgAPIVersion : 0.9.16
Culture        : de-CH
CLRVersion     : 528372
PrtgVersion    : 21.3.70.1629
PrtgLanguage   : Unknown

Additional context

We got totally 402 PRTG Groups. So it isn’t listing all the groups. I couldn’t define, how this is filtered. It isn’t a wildcard filter with “1” or something like this. Because in the result are Groups with a Parent ID’s that dosn’t contain any “1” too.

@lordmilko - Update: It is confirmed, there is a Bug in the API. With the exception of the “tags” filter, every filter actually uses wildcards unintentionally. I will be informed, when the issue is solved.

Now, the PRTG Server is on the same version as yours.

PSVersion      : 5.1.19041.1237
PSEdition      : Desktop
OS             : Microsoft Windows 10 Pro
PrtgAPIVersion : 0.9.16
Culture        : de-CH
CLRVersion     : 528372
PrtgVersion    : 21.3.71.1416
PrtgLanguage   : Unknown

Then I ran the same Query:

PS C:\> Get-Group -ParentId 1 -Verbose
VERBOSE: Get-Group: Synchronously executing request
https://[PRTG-URL]/api/table.xml?content=groups&columns=objid,name,probe,condition,fold,groupnum,devicenum,upsens,downsens,downacksens,partialdownsens,warnsens,pausedsens,unusualsens,undefinedsens,totalsens,schedule,basetype,baselink,notifiesx,intervalx,access,dependency,position,status,comments,priority,message,parentid,tags,type,active&count=*&filter_parentid=1&username=[Username]&passhash=[Hash]

And I got the same wrong result with the parameter “ParentID=1”.

The API request direct in the browser with the parameter e.g. “ParentID=12073” worked as expected. The Command “get-group” in PowerShell works here too.

So, I will open a ticket at Paessler and ask them for their input.
