Application RED Metrics

The observe-agent is able to generate application RED metrics from trace data. These metrics are needed to power the Observe APM experience.

To enable generation of RED metrics, configure the following in your values.yaml file:

# Enable RED metrics generation in order to get accurate counts while sampling
application:
  REDMetrics:
    enabled: true

With this enabled, the forwarder daemonset will use more CPU and memory (unless you enable the gateway for tail sampling, in which case there will be no difference to the forwarder daemonset). For more information on resource requirements, see Tune service resource requests and limits.
