Metrics for the host

The hostmetricsreceiver plugin for OpenTelemetry Collector collects numerous metrics about the host machine, such as CPU, RAM, disc data, and other system-level metrics.

However, OpenTelemetry lacks built-in storage and processing tools for the acquired data. Instead, you may export the data to your preferred OpenTelemetry backend, such as Prometheus or Uptrace.

To begin collecting host metrics, install Otel Collector on each machine to be monitored and add the following lines to the Collector configuration:

receivers:
  hostmetrics:
    collection_interval: 10s
    scrapers:
      # CPU utilization metrics
      cpu:
      # Disk I/O metrics
      disk:
      # File System utilization metrics
      filesystem:
      # CPU load metrics
      load:
      # Memory utilization metrics
      memory:
      # Network interface I/O metrics & TCP connection metrics
      network:
      # Paging/Swap space utilization and I/O metrics
      paging:
