Functions

func GraphToDotLanguage

func GraphToDotLanguage(g Graph) (dotLang string, err error)

GraphToDotLanguage converts a graphviz graph to a Graphviz DOT language string via a template.

func ServiceGraphToDotLanguage

func ServiceGraphToDotLanguage(
	serviceGraph graph.ServiceGraph) (dotLang string, err error)

ServiceGraphToDotLanguage converts a ServiceGraph to a Graphviz DOT language string.

Types

type Edge

type Edge struct {
	From      string
	To        string
	StepIndex int
}

Edge represents a directed edge in the Graphviz graph.

type Graph

type Graph struct {
	Nodes []Node
	Edges []Edge
}

Graph represents a Graphviz graph.

func ServiceGraphToGraph

func ServiceGraphToGraph(sg graph.ServiceGraph) (Graph, error)

ServiceGraphToGraph converts a service graph to a graphviz graph.

type Node

type Node struct {
	Name         string
	Type         string
	ErrorRate    string
	ResponseSize string
	Steps        [][]string
}

Node represents a node in the Graphviz graph.
