Functions

func GetMetricValue

func GetMetricValue(metrics NodeMetrics, name string, labels prometheus.Labels) (float64, bool)

GetMetricValue returns the value of the specified metric which has the required labels.

If multiple metrics match the provided labels, the first metric found is returned.

Only Counter and Gauge metrics are supported.

func Outf

func Outf(format string, args ...interface{})

Outputs to stdout.
