Host Metrics (opentelemetry)

Host Metrics Dashboard (OpenTelemetry)

Monitor host performance using OpenTelemetry Collector's hostmetrics receiver.

Requirements

• OpenTelemetry Collector with hostmetrics receiver
• Prometheus with OTLP ingestion enabled
• Prometheus translation strategy: UnderscoreEscapingWithSuffixes

Overview

• CPU / Memory / Root FS utilization gauges
• Load 1m, CPU Cores, Total Memory stats

CPU

• CPU Utilization over time
• System Load (1m/5m/15m with cores reference line)

Memory

• Memory Usage breakdown (used/cached/buffered/free)
• Memory Utilization over time

Disk I/O

• Throughput (read/write mirrored)

• Disk Busy %

Filesystem

• Utilization by mountpoint (bar gauge)
• Usage over time

Network

• Throughput in bps (rx/tx mirrored)
• Packets per second (rx/tx mirrored)
• Network Errors
