3 years ago /redfish/v1/ is the Redfish service root.
All redfish resources are linked from here (Redfish is a hypermedia API).
Common Redfish collections are: /redfish/v1/Systems /redfish/v1/Managers /redfish/v1/Chassis.
Under these collections you will find the ComputerSystem resource (hardcoded in bmcweb at /redfish/v1/Systems/system, the manager resource hardcoded in bmcweb at /redfish/v1/Manager/bmc)
/xyz/openbmc_project/ is our D-Bus interfaces exposed as a lightweight REST API.

More documentation on Redfish can be found at: https://www.dmtf.org/standards/redfish and https://redfish.dmtf.org/

You mentioned a sensor, depending on the sensor determines which of the 3 different Redfish resources (thermal, power, or sensors) the sensor is under (this is changing in the next Redfish release, all sensors will be under sensors). https://github.com/openbmc/bmcweb/blob/master/redfish-core/lib/sensors.hpp#L62
You must also create associations between the sensor and chassis, so bmcweb know which chassis this sensor belongs to:

HI,
I am new to openbmc and need to understand the integration of the bmcweb static files(redfish/v1) with dbus. My requirement is to update the static files in bmcweb with my custom sensor.
For example, I have created a custom power sensor, which is reading through the hwmon entry. I can read the power metrics value using the "curl" command through the "/xyz/openbmc/" path but no value is updated in the path "/redfish/v1".
So I have basically two queries,
1) What exactly is difference between the two paths, "/xyz/openbmc" & "/redfish/v1"? 2) How can we update the custom sensor values to "/redfish/v1" path? Where exactly the integration is required?
It will be really helpful if you can provide any doc for reference.
Thank you.
