In this article I will explain briefly about the JSON response from iDRAC and how you can navigate through the Redfish API tree structure to get all the required information. Now, lets have a look at the URIs.
Query the computer system collection:
$result1 = Invoke-RestMethod -Uri "https://$($idrac_ip)/redfish/v1/Systems"
-Credential $Credentials -Method Get -UseBasicParsing -ContentType 'application/json'
Response:
You can see one member with URI /redfish/v1/Systems/System.Embedded.1
Below is a sample screen shot of JSON output when you try to query the above listed member system.
You can get some of the basic information straight away from the above JSON response. And these are organized in hierarchy where you can drill down to each object and get the required details. Below diagram shows basic iDRAC Redfish API tree structure.
Example: You can get details/ health status of storage controller as shown below.
Query:
$result2 = Invoke-RestMethod
-Uri "https://$($idrac_ip)/redfish/v1/Systems/System.Embedded.1/Storage
/Controllers/NonRAID.Integrated.1-1" -Credential $Credentials -Method Get
-UseBasicParsing -ContentType 'application/json'
