Host Resource Monitor

Software componentObservability & EvaluationObservability & Evaluationarc:HostResourceMonitor

A monitoring component that samples host CPU, memory, disk and network usage and raises alerts when utilization approaches critical limits.

Responsibility. Watches host-level resource utilization and alerts on critical levels.

Also known as: CPU and host memory monitoring

Design guidance

SHOULD monitor CPU, host memory and disk continuously alongside GPU utilization.

Quantitative guidance

As stated by the sources; verify before use.

Alert when host memory > 85% or disk > 90% (Ref8.05).
