appender

type Appender ¶

type Appender interface {
	// AppendGraph performs the appender work on the provided traffic map. The map
	// may be initially empty. An appender is allowed to add or remove map entries.
	AppendGraph(trafficMap graph.TrafficMap, namespace string)
}

Appender is implemented by any code offering to append a service graph with supplemental information. On error the appender should panic and it will be handled as an error response.

type DeadNodeAppender ¶ added in v0.6.0

type DeadNodeAppender struct{}

DeadNodeAppender is responsible for removing from the graph unwanted nodes:

• nodes for which there is no traffic reported and the related schema is missing (presumably removed from K8S). (kiali-621)
• service nodes for which there is no incoming error traffic and no outgoing edges (kiali-1326)

func (a DeadNodeAppender) AppendGraph(trafficMap graph.TrafficMap, _ string)

type IstioAppender ¶

type IstioAppender struct{}

func (a IstioAppender) AppendGraph(trafficMap graph.TrafficMap, namespace string)

type ResponseTimeAppender ¶

type ResponseTimeAppender struct {
	Duration     time.Duration
	GraphType    string
	IncludeIstio bool
	Quantile     float64
	QueryTime    int64 // unix time in seconds
}

ResponseTimeAppender is responsible for adding responseTime information to the graph. ResponseTime is represented as a percentile value. The default is 95th percentile, which means that 95% of requests executed in no more than the resulting milliseconds.

func (a ResponseTimeAppender) AppendGraph(trafficMap graph.TrafficMap, namespace string)

type SecurityPolicyAppender ¶ added in v0.6.0

type SecurityPolicyAppender struct {
	Duration     time.Duration
	GraphType    string
	IncludeIstio bool
	QueryTime    int64 // unix time in seconds
}

SecurityPolicyAppender is responsible for adding securityPolicy information to the graph. The appender currently reports only mutual_tls security although is written in a generic way.

func (a SecurityPolicyAppender) AppendGraph(trafficMap graph.TrafficMap, namespace string)

type SidecarsCheckAppender ¶

type SidecarsCheckAppender struct{}

func (a SidecarsCheckAppender) AppendGraph(trafficMap graph.TrafficMap, _ string)

type UnusedNodeAppender ¶ added in v0.6.0

type UnusedNodeAppender struct {
	GraphType string
}

func (a UnusedNodeAppender) AppendGraph(trafficMap graph.TrafficMap, namespace string)
