con/duct: v0.13.0
Year: 2025
Type: software
Abstract: Release Notes Add plot --cpu modes, including ps-cpu-timepoint for derived instantaneous CPU (#424) Change: con-duct plot now shows per-pid traces with max-across-pids and totals.* envelopes. Previously it drew only totals.pcpu and totals.rss as a single line per metric, with no per-pid breakdown. Change: con-duct plot now shows absolute rss on a secondary y-axis instead of pmem. Motivated by SLURM, where pmem = rss / host_total makes job usage look tiny on big nodes. Change: con-duct plot drops vsz from the secondary y-axis, since this is a rarely useful metric. Add: host available RAM in the legend when info.json is available. Add: --cpu argument to con-duct plot: --cpu ps-pcpu (default): plot ps's raw lifetime pcpu per pid, untransformed. Every point on the chart is an unaltered ps reading. --cpu ps-cpu-timepoint: at plot time, derive a per-interval estimate from consecutive (pcpu, etime) pairs to approximate instantaneous CPU. Sidesteps lifetime-average inflation on short-lived bursty pids. Change: con-duct run warns when --sample-interval is below 1.0s. ps reports etime as integer seconds, so pcpu calculations for sub-second-young pids are unstable. Change: byte humanization in con-duct plot is now decimal (base 1000, kB/MB/GB), matching the run summary. Previously the plot used base-1024 with decimal-style suffixes. Docs: new docs/resource-statistics.md explains what duct's pcpu / rss / pmem actually measure, how aggregation works, and how con-duct plot renders these.
