The Grafana Agent Flow component controller exposes Prometheus metrics which you can use to investigate the controller state.
Metrics for the controller are exposed at the
/metrics HTTP endpoint of the Grafana Agent Flow HTTP server, which defaults to listening on
The documentation for the
grafana-agent runcommand describes how to modify the address Grafana Agent Flow listens on for HTTP traffic.
The controller exposes the following metrics:
agent_component_controller_evaluating(Gauge): Set to
1whenever the component controller is currently evaluating components. This value may be misrepresented depending on how fast evaluations complete or how often evaluations occur.
agent_component_controller_running_components(Gauge): The current number of running components by health. The health is represented in the
agent_component_evaluation_seconds(Histogram): The time it takes to evaluate components after one of their dependencies is updated.
agent_component_dependencies_wait_seconds(Histogram): Time spent by components waiting to be evaluated after one of their dependencies is updated.
agent_component_evaluation_queue_size(Gauge): The current number of component evaluations waiting to be performed.
