Host CPU, memory and load per core, container CPU and memory, and every monitor's response time learn a normal per hour (milestone 513, System 182). A reading past its fixed cutoff but within its normal reads healthy and says what is usual at this hour; one well out of it keeps its grade and is a metric anomaly. Disk, a monitor down and an agent offline keep their cutoffs. - Each normal's floor, the smallest departure that counts, is a setting: Settings -> Thresholds -> Normals (norms.floor.*). Defaults: host CPU 10 points, host memory 5, load per core 10, container CPU 10 points of one core, container memory 5, monitor response 100 ms; Traefik's 2-point 4xx and 50 ms p95 floors move there from constants. learn_normal takes a floor function (floor_setting) read at each pass. - learn_normal(parts=False): a host learns, its cores don't. - Ingest records load_pct (load_1m / cores x 100), the figure pages grade. - Shared grading: anomalies.against / graded, worst_reading(normals=), hosts' host_grades, docker usage(thresholds=, norms=), monitors' latency_grade. Applied to host vitals, the Hosts widget, MCP overview, Docker usage, and the monitor list, widget and page. - The monitor and container pages list their anomalies.
