Summarise a garry.task_log CSV.

Summarises the task log CSV the distributed scheduler writes when the garry.task_log option is set (see garry_options(); schema time,event,key,pool,slot,mb,store_mb,ready): per-stage task counts and run/queue-wait quantiles, maximum concurrency, the drain vs host-tail split, and the peak measured (per-daemon anonymous RSS) vs modelled (in-flight + resident) memory. It answers "where did the time and memory go" for a distributed run.

Usage

garry_task_report(path)

Arguments

path

Path to a task-log CSV written by the scheduler.
