Collect Airflow CFM metric

[rsdoherty]

I've been playing around with getting Airflow (in cubic feet per minute) exported and have this working locally.

On Dell's, you can fetch this via the following API key:

/redfish/v1/Systems/System.Embedded.1/Oem/Dell/DellSystem/System.Embedded.1

The metric is exposed in the EstimatedSystemAirflowCFM key.

Ideally I'd like to get this into the upstream repository, but I don't have HP or Lenovo systems to test and contribute this myself. Would any of the maintainers be able to look into this? Thanks!

Hi @rsdoherty

These kind of OEM specific metrics can of course be implemented and your request is a bit similar to the request in #114. I have been debating whether or not to include them, but I see no harm in doing it, as long as they are placed in a separate metrics groups, such that people can select if they should be scraped or not.

@mrlhansen - if you have HP/Lenovo systems to check with, it would be good to see if the airflow metric is exposed on those OEM's, then it can be implemented for all?

I cannot find something similar on HPE or Lenovo, but as I said, this can go under some dell specific metrics group.
