Variables ¶

View Source

var Cell = cell.Module(
	"operator-metrics",
	"Operator Metrics",

	certloaderGroup,
	cell.Config(defaultConfig),

	cell.Provide(func(conf Config) metrics.RegistryConfig {
		return metrics.RegistryConfig{
			PrometheusServeAddr: conf.OperatorPrometheusServeAddr,
		}
	}),

	metrics.NewCell("operator"),
	cell.Invoke(initializeMetrics),
)

Cell provides the modular metrics registry, metric HTTP server and legacy metrics cell for the operator.

Functions ¶

func DumpMetrics ¶

func DumpMetrics(reg *metrics.Registry) ([]*models.Metric, error)

DumpMetrics gets the current Cilium operator metrics and dumps all into a Metrics structure. If metrics cannot be retrieved, returns an error.

For histogram metrics, three entries are emitted with a "quantile" label set to "0.5", "0.9", and "0.99" respectively, each holding the computed quantile value. For summary metrics, one entry per predefined quantile is emitted with the corresponding "quantile" label.

Types ¶

type Config ¶ added in v1.15.0

type Config struct {
	OperatorPrometheusServeAddr string
	EnableMetrics               bool
}

Config contains the configuration for the operator-metrics cell.

func (Config) Flags ¶ added in v1.15.0

func (def Config) Flags(flags *pflag.FlagSet)
