Overview

Package host provides the conventional host metric instruments specified by OpenTelemetry. Host metric events are sometimes collected through the OpenTelemetry Collector "hostmetrics" receiver running as an agent; this instrumentation is an alternative for processes that want to record the same information without an agent.

The metric events produced are listed here with attribute dimensions.

Name			Attribute

----------------------------------------------------------------------

process.cpu.time           state=user|system
system.cpu.time            state=user|system|other|idle
system.memory.usage        state=used|available
system.memory.utilization  state=used|available
system.network.io          direction=transmit|receive

See https://github.com/open-telemetry/oteps/blob/main/text/0119-standard-system-metrics.md for the definition of these metric instruments.
