unit: bytes · min/avg/med/max/σ/p5/p25/p75/p95 over the window shown · k/M/G step by 1024, as the graph legend's do · σ and the percentiles show '-' where the window held too few samples for them to mean anything, the cell naming how few · Δ vs the preceding equal window · a paired column sorts by either half
field — the plugin's label for the field, or its name where it gave none; the swatch is the colour the graph drew it with	cur — the newest consolidated value in the window shown	min — lowest value over the window shown — where the window is served by a coarser archive this is the true minimum, read from the RRD's own MIN archive rather than taken from the averaged rows; a field with a cdef stays on those averaged rows, since the minimum of a difference is not the difference of the minima	avg — mean of the consolidated values over the window shown	med — median of the consolidated values over the window shown — always an actual sample (the upper middle on even counts, never an interpolated value); beside avg so skew is visible at a glance	max — highest value over the window shown — where the window is served by a coarser archive this is the true maximum, read from the RRD's own MAX archive rather than taken from the averaged rows, so a spike inside one consolidated bin still shows; a field with a cdef stays on those averaged rows, since the maximum of a difference is not the difference of the maxima	σ — population standard deviation of the consolidated values over the window shown — an approximation over consolidated rows on long windows, unlike min and max, which read the RRD's own MIN/MAX archives there (except on a field with a cdef)	p5…p95 — 5th and 95th percentiles (linear interpolation) of the consolidated values over the window shown — the robust floor and ceiling beside min's and max's literal ones, for the fields where one unlucky bin is not the story; sort by either half. An approximation over consolidated rows on long windows, unlike min and max, which read the RRD's own MIN/MAX archives there (except on a field with a cdef)	p25…p75 — 25th and 75th percentiles of the consolidated values over the window shown — the box around med: half the window's samples lie between them, so the spread they show is one no single excursion can move, where σ beside them is a squared distance that skew drags around	Δ — this window's average against the preceding equal window's, as a signed percentage; consolidation may differ between the two windows on fine-rung boundaries, and a cell whose two windows came back at different resolutions says so on hover; '-' when the previous window offers no baseline — hover for why	warn/crit — the values that breach this field to WARNING and to CRITICAL, in that order; hover either half for the range as configured	limits — the plugin's declared min/max: values outside this range are stored as UNKNOWN rather than clipped (rrdcreate's DS min/max); hover a cell for the exact bounds	state·since — the verdict at the last poll, and how long the field has been in it — hover the word for what it means; a steady OK has no transition on record and shows none	info — the plugin's description of the field, and its own note about a breach

dark mode inverts graph colours; field-table swatches, where shown, are inverted too so they match the curves
