Browse code skydick/monitoring: add zpool_io physical pool IOPS collector Telegraf inputs.zfs poolMetrics emits per-objset logical read/write counters that include ARC cache hits, so RAM-served reads appear as huge pool IOPS with zero disk activity (misled a 2026-05-30 mountd probe). Add a zpool-iostat exec collector emitting real vdev-layer ops as measurement zpool_io for an honest physical-IOPS view. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> main

Telegraf inputs.zfs poolMetrics emits per-objset *logical* read/write
counters that include ARC cache hits, so RAM-served reads appear as huge
pool IOPS with zero disk activity (misled a 2026-05-30 mountd probe). Add
a zpool-iostat exec collector emitting real vdev-layer ops as measurement
zpool_io for an honest physical-IOPS view.
