metrics

Downsampled time series from metrics.db — throughput, CPU, RAM, SMART history. Read-only; never probes block devices.

📄️Metric time series

Returns downsampled samples from metrics.db for one metric/subject over a time window. Resolution is chosen from the window — raw for up to 48 hours, hourly for up to 90 days, daily beyond — so clients cannot force a full raw scan. A missing or empty metrics.db yields an empty series, not an array-health error.
