Description

Monitors ZFS performance and cache behavior on a host by displaying I/O timing and I/O throughput alongside ARC activity. It highlights read/write times and ZFS pool I/O operations with panels like ZPOOL - Time, ZPOOL - Ops, and cache efficiency through ARC - Hit % / ARC - Hits, Misses and ARC - Size. The dashboard also includes detailed ARC and L2ARC statistics, such as ARC L2 - Hit %, ARC L2 - Hits, Misses, and ARC L2 - Size, to help assess memory usage and data access performance.
