Types

type AuthServer

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

AuthServer authenticates incoming requests via Grafana API.

func NewAuthServer

func NewAuthServer(c clientInterface, checker awsInstanceChecker) *AuthServer

NewAuthServer creates new AuthServer.

func (*AuthServer) ServeHTTP

func (s *AuthServer) ServeHTTP(rw http.ResponseWriter, req *http.Request)

ServeHTTP serves internal location /auth_request for both authentication subrequests and subsequent normal requests.

type Client

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

Client represents a client for Grafana API.

func NewClient

func NewClient(addr string) *Client

NewClient creates a new client for given Grafana address.

func (*Client) Collect

func (c *Client) Collect(ch chan<- prom.Metric)

Collect implements prometheus.Collector.

func (*Client) CreateAnnotation

func (c *Client) CreateAnnotation(ctx context.Context, tags []string, from time.Time, text, authorization string) (string, error)

CreateAnnotation creates annotation with given text and tags ("pmm_annotation" is added automatically) and returns Grafana's response text which is typically "Annotation added" or "Failed to save annotation".

func (*Client) Describe

func (c *Client) Describe(ch chan<- *prom.Desc)

Describe implements prometheus.Collector.

func (*Client) IsReady

func (c *Client) IsReady(ctx context.Context) error

IsReady calls Grafana API to check its status
