> For now, the system metrics demux parser are storing raw metrics. Each system components are measured independently. It would be nice to make a summary grouping for cpu, disk, network. Instead of storing cpu:combined.0 ... cpu:combined.8, for 8 cpu cores in the system, it would be nice to have a average number for all cpus combined. The digested metrics are easier to aggregate at cluster level.
