Types

type Arguments

type Arguments struct {
	// Where the relabelled metrics should be forwarded to.
	ForwardTo []*prometheus.Receiver `river:"forward_to,attr"`

	// The relabelling rules to apply to each metric before it's forwarded.
	MetricRelabelConfigs []*flow_relabel.Config `river:"rule,block,optional"`
}

Arguments holds values which are used to configure the prometheus.relabel component.

type Component

type Component struct {
	// contains filtered or unexported fields
}

Component implements the prometheus.relabel component.

func New

func New(o component.Options, args Arguments) (*Component, error)

New creates a new prometheus.relabel component.

func (*Component) Receive

func (c *Component) Receive(ts int64, metricArr []*prometheus.FlowMetric)

Receive implements the receiver.Receive func that allows an array of metrics to be passed around. TODO (@tpaschalis) The relabelling process will run _every_ time, for all metrics, resulting in some serious CPU overhead. We should be caching the relabeling results per refID and clearing entries for dropped or stale series. This is a blocker for releasing a production-grade version of the prometheus.relabel component.

func (*Component) Run

func (c *Component) Run(ctx context.Context) error

Run implements component.Component.

func (*Component) Update

func (c *Component) Update(args component.Arguments) error

Update implements component.Component.

type Exports

type Exports struct {
	Receiver *prometheus.Receiver `river:"receiver,attr"`
}

Exports holds values which are exported by the prometheus.relabel component.
