Implement EnvironmentMetrics

Need EnvironmentMetrics for PowerConsumedWatts
https://github.com/search?q=org%3Aopenbmc+PowerConsumedWatts&type=code

PowerConsumedWatts is called PowerWatts in EnvironmentMetrics

For now just put EnvironmentMetrics out on Chassis and implement PowerWatts

@gtmills There are some questions about the data that needs to be implemented.

1.For the "TemperatureCelsius";
See the description in the introduction, this is the reading value of the sensor temperature,
and the data comes from CPU1Temp,
My question is as follows:
1>If there are two or more CPUs, how to choose?
Should all the CPU data be listed, or just take the first one;
or take the average of all the data (this method is very undesirable but it is also possible )
2>On our machine, the PSU is not named CPU1Temp, but cpu0,
and there is no reading value in the data under cpu0.
How to solve this? Is it necessary to add a CPU1Temp related sensor first,
Could you provide relevant help?
3>And its type is null,
This is a little unclear.

2.For the "PowerWatts";
similar to the question above,it is the total power,
in our machine,there is no /redfish/v1/Chassis/1U/Sensors/TotalPower,
how can this be achieved,please give some help.

Sorry for not responding sooner, at this time we just need PowerWatts in EnvironmentMetrics.
That is what we are trying to replace.
I am fine if we also want to add Fan speeds but let's make sure we concentrate on PowerWatts which is the replacement for PowerConsumedWatts

@gtmills Okay, for PowerWatts in EnvironmentMetrics.
The data comes from /redfish/v1/Chassis/chassisId/Sensors/TotalPower;
For the sensor called TotalPower, it does not exist on our machine;
this should be about reading the power of the entire chassis; how to get this data.
Does the sensor module need to add a sensor named TotalPower first?

The data comes from /redfish/v1/Chassis/chassisId/Sensors/TotalPower;

Yes, https://github.com/openbmc/bmcweb/blob/9a128eb3fc3008f802974360e98de6495ed1a66b/redfish-core/lib/sensors.hpp#L1007
https://github.com/search?q=org%3Aopenbmc+total_power&type=code

It only exists on ours when the system is booted.

Does the sensor module need to add a sensor named TotalPower first?

Anyway you can a sensor like this to your machine?

[zhanghaodi]

Thank you, I am trying to make a similar sensor exist in our machine.

@zhanghaodi Can we pull this one and #2793 in downstream?
