Default Metrics

The following metrics are emitted by default. Each of them can be disabled by applying the following configuration:

metrics:
  <metric_name>:
    enabled: false

system.cpu.time

Total seconds each logical CPU spent on each mode.

Unit	Metric Type	Value Type	Aggregation Temporality	Monotonic
s	Sum	Double	Cumulative	true

Attributes

Name	Description	Values
cpu	Logical CPU number starting at 0.	Any Str
state	Breakdown of CPU usage by type.	Str: idle, interrupt, nice, softirq, steal, system, user, wait

Optional Metrics

The following metrics are not emitted by default. Each of them can be enabled by applying the following configuration:
