Types

type Client

type Client struct {
	HostPort string
}

func (*Client) Query

func (c *Client) Query(promQL string) ([]Result, error)

type Result

type Result struct {
	Metric map[string]string `json:"metric"`
	Value  []interface{}
}

type ScrapedMetric

type ScrapedMetric struct {
	Name   string
	Value  float64
	Labels map[string]string
}
