Revision history for OSLV-Monitor

1.0.5   2026-07-24/20:00
        - cgroups: fix io.stat parsing so IO stats are recorded
        - cgroups: emit throttled/burst/force_idle-time, percpu, thp_swpout, and zswpwb stats
        - cgroups: fix container IP mapping key and cache-save error message
        - cgroups: populate path with container rootfs, falling back to the roots
          seen by the procs in the cgroup, matching jail path semantics
        - cgroups: treat nr_periods, nr_throttled, and nr_bursts as counters so
          they are rates like throttled-time and burst-time, matching what the
          LibreNMS graphs expect
        - both: when a counter is seen for the first time, return 0 instead of the
          accumulated total over 300 if what it is for is older than the polling
          interval, preventing spikes when something old is first seen... procs
          younger than the polling interval are still processed as fresh counters
          so short lived procs don't go uncounted
        - cgroups: don't zero the cached raw counter value when discarding a
          garbage value, preventing a inflated delta on the following run
        - cgroups: remove unused raw usec names from the counters list
        - FreeBSD: fix MM:SS CPU time parsing
        - FreeBSD: guard against counter rollback
        - FreeBSD: populate jail path
        - both: self-heal a corrupt/truncated cache instead of erroring every run
        - both: write the cache atomically to avoid truncated cache files
        - fix leaked $@ that turned a handled cache error into "Failed to run backend"
        - do not include idle
