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          direction=transmit|receive

See for the definition of these metric instruments.
