major faults

field name: major — what munin.conf and the RRD call it
unit: faults per ${graph_period}
state: OK
thresholds: no warning · no critical
limits: ≥ 0 — values outside this range are stored as UNKNOWN rather than clipped (rrdcreate's DS min/max)
about: pgmajfault: page faults that required a disk read.
data source: localhost/localhost-vmstat-faults-major-d.rrd · DERIVE

24-hour profile (daily model, mean ± σ, server-local time — CEST, UTC+02:00) · the second line is the last 24 hours, ending at the marker

the numbers behind this figure — 48 half-hour slots

unit: faults per ${graph_period} · typical is the daily model's mean at that local half-hour, band its mean ∓ σ held inside the field's declared range, n the samples pooled behind it, and last 24 h what the field actually did on the same slot

hour × weekday (weekly model mean, server-local time — CEST, UTC+02:00)

the numbers behind this figure — 7 weekdays × 12 buckets

unit: faults per ${graph_period} · each cell is the weekly model's mean over that local bucket, with n the samples pooled behind it — the same value and pool the coloured cell above carries
