Functions

func DisableUnavailableCollectors 

func DisableUnavailableCollectors(cs map[string]CollectorState)

DisableUnavailableCollectors disables collectors that are not available on the host machine.

func MapCollectorsToFlags 

func MapCollectorsToFlags(cs map[string]CollectorState) (flags []string)

MapCollectorsToFlags takes in a map of collector keys and their states and converts them into flags that node_exporter expects. Collectors that are not defined will be ignored, which will be the case for collectors that are not supported on the host system.

func MapConfigToNodeExporterFlags 

func MapConfigToNodeExporterFlags(c *Config) (accepted []string, ignored []string)

MapConfigToNodeExporterFlags takes in a node_exporter Config and converts it to the set of flags that node_exporter usually expects when running as a separate binary.

Types

type Collector 

type Collector string

Collector is a specific collector that node_exporter runs.

type CollectorState 

type CollectorState bool

CollectorState represents the default state of the collector, where it can either be enabled or disabled 

const (
	// CollectorStateDisabled represents a disabled collector that will not run
	// and collect metrics.
	CollectorStateDisabled CollectorState = false

	// CollectorStateEnabled represents an enabled collector that _will_ run
	// and collect metrics.
	CollectorStateEnabled CollectorState = true
)
