Changes for version 1.0.5 - 2026-07-24
- 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
