Hiddend fields in json reponse with new Jenkins version

Using Jenkins Ask a question
1

Hi All.
I need to get architecture information of nodes using api/json.
Performing GET request from browser everything works, but if I try to use SoapUI or PostMan, some fields are “hidden” and I cannot access to content.
In particular the http request is:
http://“jenkinsURL”/computer/api/json?tree=computer[displayName,monitorData[[]]]&pretty=true

Using old versions of Jenkins (2.360) I am able to get the complete response (the same I get using browser). Using new versions (2.440.2) the response json is not complete.

Here the complete response I expect:

Here the response I get using latest version of Jenkins:

{
   "_class": "hudson.model.ComputerSet",
   "computer":    [
            {
         "_class": "hudson.model.Hudson$MasterComputer",
         "displayName": "Built-In Node",
         "monitorData": {}
      },
            {
         "_class": "hudson.slaves.SlaveComputer",
         "displayName": "nodeAUT_1",
         "monitorData": {}
      },
            {
         "_class": "hudson.slaves.SlaveComputer",
         "displayName": "winAUT_1",
         "monitorData": {}
      },
            {
         "_class": "hudson.slaves.SlaveComputer",
         "displayName": "winAUT_3",
         "monitorData": {}
      },
            {
         "_class": "hudson.slaves.SlaveComputer",
         "displayName": "winAUT_7",
         "monitorData": {}
      }
   ]
}

Is there anybody who has the same behavior?
Is there anything I can do?

Thank you!

Using /computer/api/json?tree=computer[displayName,monitorData[*]]&pretty=true worked for me against 2.440.1 with postman and curl giving the expected output

3

Really? What could be wrong in my Jenkins instance? What could hide the “monitorData” field details?
I cannot understand what I can do to have the wanted behavior on new instance as well.

4

Is there anybody who can help me in getting this info from api request?

5

can you try with
/computer/api/json?tree=computer[displayName,monitorData[*]]&pretty=true&depth=2
Are you doing this as an administrator?
Does it work when using xml instead of json?

6

Trying “computer[displayName,monitorData[*]]&pretty=true&depth=2” the result does not change: I get:

The same if I use xml instead of json.

If I use browser it works properly and I get the wanted info, but using soapUI or postMan the info I need into monitorData cannot be accessed (as shown in the snippets of the original message). Obviously, even when I try to get those info using cxf library in Java I cannot get the info.
What could cause those different behaviours?

Is the user the same that you used in postman and SOAP that you used when you checked in the browser?
Monitoringdata is not available to everyone. Although architecture data should be available

You are perfectly rigth. I had no permission to see that field details.
Thank you very much for the hint!
