It ships with a procfs-native field kit ( mem , oom , throttle ) for the three incidents every operator meets. command answers --- --- pstax top live table of pseudo-fs read traffic by file pattern, process, or container pstax advise which reads are wasted: duplicate opens per cycle, smaps instead of smaps rollup , full-PID sweeps, known-expensive files pstax record / report / diff headless capture → tables, fleet cost projection in cores and dollars, before/after comparison pstax mem is memory growth a leak, page cache, slab churn, tmpfs — or just pressure?

It reads only procfs, so it runs instantly on any box. When an incident needs full forensics, the dedicated tools go deeper: oomtale recomputes the kernel's oom badness() to rank victims and answer \"who dies next\"; stealsense learns your instance limits from IMDS and pins down when cloud thro","default_branch":null,"files":null,"tree":[],"storefront":"/r/agenticode","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/agenticode/pstax/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
