Get inventory FRU from inventory system path

[-- Attachment #1: Type: text/plain, Size: 1775 bytes --]

Hi,

I am trying to get the data from this path “https://<bmcip>/xyz/openbmc_project/inventory/system<https://%3cbmcip%3e/xyz/openbmc_project/inventory/system>”.
But only get the following data from this path.

"/xyz/openbmc_project/inventory/system": {
"AssetTag": ""
},

Here is an example for this path which I expected to get.

    "/xyz/openbmc_project/inventory/system": {
        "BuildDate": "",
        "Cached": 0,
        "FieldReplaceable": 0,
        "Manufacturer": "",
        "Model": "2",
        "PartNumber": "0000000000000000",
        "Present": 1,
        "PrettyName": "",
        "SerialNumber": "0000000000000000"
    },



Only using entity-manager in my project for inventory FRU.
I could get the FRU data from this path “https://<bmcip>/xyz/openbmc_project/inventory/system/board/<name>”
But the inventory system path is null.

Any setting I should set for getting FRU from this path?

Regards,
John Chung

Hi John,

What are you trying to achieve?
The REST API do just a translation to dbus, so you expect to get
exactly what EntityManager (or other inventory-related daemon) expose.
And EM expose nothing to /xyz/openbmc_project/inventory/system

Hi Andrei,

> What are you trying to achieve?
I am trying to display the system information section in phosphor-webui.
This section would call the 'getServerInfo' function. 
The function would need to using the "/xyz/openbmc_project/inventory/system" path.

Yes, I want to get exactly what EntityManager (or other inventory-related daemon) expose.
But it's null for this dbus path now.

Right, there is no info there, /xyz/openbmc_project/inventory/system is
kind of parent node, id doesn't store any information. That is how EM
works.
In our system we use our custom interface for baseboard to provide this
kind of information.
