Description
Hey,
I'm new to using cadvisor together with InfluxDB but from what I understood we can't specify a set of labels to be retrieved from containers and sent to influx - all of them are sent.
In my use case that's a problem as we don't control the full set of labels that a user can attach to his/her container (whilst we only need one or two labels that our platform defines).
I noticed that for Prometheus there's a way of programmatically specifying the set of labels to be retrieved (#1429) but I think something more like -docker_env_metadata_whitelist string could be useful for not only InfluxDB users but also those using other storage drivers which are sending possibly more labels than the desired.
I couldn't find another issue about this so I think it's not a duplicate (please let me know if this is incorrect!)
I'd be willing to implement this if desired 👍
Wdyt?
Thx!
