/**

 * Get system metrics

 * Get a Network Controller system metric: cpu, disk, diskIO and memory (averaged over the last 5 minutes), their *Usage variants (time series over a timespan, default 1h), or uptime (days). Returns one entry per Network Controller, or only node_id's when set. The timespan only applies to the *Usage metrics.
