OpenTelemetry Collector on a Host Enviroment
- Harold Lim
Refer to the following instructions for installing OpenTelemetry Collector on a Host Enviroment, such as BareMetal host or on a VM instance. Refer to the following sample yaml for configuration. Note that kf_platform with host as value is a required resource attribute. Also refer to OpenTelemetry Runtime Metrics for additional details regarding runtime metrics.

Host Level Metrics
The Kfuse APM Services page integrates with host metrics to show related infrastructure metrics.
The metrics can be exported into Kfuse using Datadog or from the OpenTelemetry collector itself.
If using OpenTelemetry Collector, the OpenTelemetry Collector needs to be updated with additional configurations. Specifically, enable hostmetrics receivers and add additional kf_metrics_agent resource attributes.
