Functions

func RegisterControlRoutes

func RegisterControlRoutes(router *mux.Router)

RegisterControlRoutes registers the various control routes with a http mux.

func RegisterReportPostHandler

func RegisterReportPostHandler(a Adder, router *mux.Router)

RegisterReportPostHandler registers the handler for report submission

func RegisterTopologyRoutes

func RegisterTopologyRoutes(c Reporter, router *mux.Router)

RegisterTopologyRoutes registers the various topology routes with a http mux.

func URLMatcher

func URLMatcher(pattern string) mux.MatcherFunc

URLMatcher uses request.RequestURI (the raw, unparsed request) to attempt to match pattern. It does this as go's URL.Parse method is broken, and mistakenly unescapes the Path before parsing it. This breaks %2F (encoded forward slashes) in the paths.

Types

type APINode

type APINode struct {
	Node render.DetailedNode `json:"node"`
}

APINode is returned by the /api/topology/{name}/{id} handler.

type APITopology

type APITopology struct {
	Nodes render.RenderableNodes `json:"nodes"`
}

APITopology is returned by the /api/topology/{name} handler.

type APITopologyDesc

type APITopologyDesc struct {
	Name    string                         `json:"name"`
	Options map[string][]APITopologyOption `json:"options"`

	URL           string            `json:"url"`
	SubTopologies []APITopologyDesc `json:"sub_topologies,omitempty"`
	Stats         topologyStats     `json:"stats,omitempty"`
	// contains filtered or unexported fields
}

APITopologyDesc is returned in a list by the /api/topology handler.

type APITopologyOption

type APITopologyOption struct {
	Value   string `json:"value"`
	Display string `json:"display"`
	Default bool   `json:"default,omitempty"`
	// contains filtered or unexported fields
}

APITopologyOption describes a &param=value to a given topology.

type Adder

type Adder interface {
	Add(report.Report)
}

Adder is something that can accept reports. It's a convenient interface for parts of the app, and several experimental components.

type Collector

type Collector interface {
	Reporter
	Adder
}

A Collector is a Reporter and an Adder

func NewCollector

func NewCollector(window time.Duration) Collector

NewCollector returns a collector ready for use.

type PipeRouter

type PipeRouter struct {
	sync.Mutex
	// contains filtered or unexported fields
}

PipeRouter connects incoming and outgoing pipes.

func RegisterPipeRoutes

func RegisterPipeRoutes(router *mux.Router) *PipeRouter

RegisterPipeRoutes registers the pipe routes

func (*PipeRouter) Stop

func (pr *PipeRouter) Stop()

Stop stops the pipeRouter

type Reporter

type Reporter interface {
	Report() report.Report
	WaitOn(chan struct{})
	UnWait(chan struct{})
}

Reporter is something that can produce reports on demand. It's a convenient interface for parts of the app, and several experimental components.
