Additional metrics - they're not counting flows, so are not served via Hubble metrics API, but belong to the same Prometheus namespace.

Functions

func EnableMetrics

func EnableMetrics(log logrus.FieldLogger, metricsServer string, metricsTLSConfig *certloader.WatchedServerConfig, m []string, grpcMetrics *grpc_prometheus.ServerMetrics, enableOpenMetrics bool) error

EnableMetrics starts the metrics server with a given list of metrics. This is the function Cilium uses to configure Hubble metrics in embedded mode.

func ProcessFlow

func ProcessFlow(ctx context.Context, flow *pb.Flow) error

ProcessFlow processes a flow and updates metrics

func ProcessPodDeletion

func ProcessPodDeletion(pod *slim_corev1.Pod) error

func Register

func Register(cs ...prometheus.Collector)

Register registers additional metrics collectors within hubble metrics registry.

Types
