type BasicNodeSummary added in v1.7.0

type BasicNodeSummary struct {
	ID         string `json:"id"`
	Label      string `json:"label"`
	LabelMinor string `json:"labelMinor"`
	Rank       string `json:"rank"`
	Shape      string `json:"shape,omitempty"`
	Tag        string `json:"tag,omitempty"`
	Stack      bool   `json:"stack,omitempty"`
	Pseudo     bool   `json:"pseudo,omitempty"`

BasicNodeSummary is basic summary information about a Node, sufficient for rendering links to the node.

func MakeBasicNodeSummary added in v1.7.0

func MakeBasicNodeSummary(r report.Report, n report.Node) (BasicNodeSummary, bool)

MakeBasicNodeSummary returns a basic summary of a node, if possible. This summary is sufficient for rendering links to the node.

type Column added in v0.13.0

type Column struct {
	ID          string `json:"id"`
	Label       string `json:"label"`
	DefaultSort bool   `json:"defaultSort"`
	Datatype    string `json:"dataType"`

Column provides special json serialization for column ids, so they include their label for the frontend.

type Connection added in v0.14.0

type Connection struct {
	ID         string               `json:"id"`     // ID of this element in the UI.  Must be unique for a given ConnectionsSummary.
	NodeID     string               `json:"nodeId"` // ID of a node in the topology. Optional, must be set if linkable is true.
	Label      string               `json:"label"`
	LabelMinor string               `json:"labelMinor,omitempty"`
	Metadata   []report.MetadataRow `json:"metadata,omitempty"`

Connection is a row in the connections table.

type ConnectionsSummary added in v0.14.0

type ConnectionsSummary struct {
	ID          string       `json:"id"`
	TopologyID  string       `json:"topologyId"`
	Label       string       `json:"label"`
	Columns     []Column     `json:"columns"`
	Connections []Connection `json:"connections"`

ConnectionsSummary is the table of connection to/form a node

type ControlInstance

type ControlInstance struct {
	ProbeID string
	NodeID  string
	Control report.Control

ControlInstance contains a control description, and all the info needed to execute it.

func (*ControlInstance) CodecDecodeSelf added in v0.13.0

func (c *ControlInstance) CodecDecodeSelf(decoder *codec.Decoder)

CodecDecodeSelf implements codec.Selfer

func (*ControlInstance) CodecEncodeSelf added in v0.13.0

func (c *ControlInstance) CodecEncodeSelf(encoder *codec.Encoder)

CodecEncodeSelf marshals this ControlInstance. It takes the basic Metric rendering, then adds some row-specific fields.

func (ControlInstance) MarshalJSON added in v0.13.0

func (ControlInstance) MarshalJSON() ([]byte, error)

MarshalJSON shouldn't be used, use CodecEncodeSelf instead

func (*ControlInstance) UnmarshalJSON added in v0.13.0

func (*ControlInstance) UnmarshalJSON(b []byte) error

UnmarshalJSON shouldn't be used, use CodecDecodeSelf instead

type Diff added in v0.14.0

type Diff struct {
	Add    []NodeSummary `json:"add"`
	Update []NodeSummary `json:"update"`
	Remove []string      `json:"remove"`
	Reset  bool          `json:"reset,omitempty"`

Diff is returned by TopoDiff. It represents the changes between two NodeSummary maps.

func TopoDiff added in v0.14.0

func TopoDiff(a, b NodeSummaries) Diff

TopoDiff gives you the diff to get from A to B.

type Node

type Node struct {
	Controls    []ControlInstance    `json:"controls"`
	Children    []NodeSummaryGroup   `json:"children,omitempty"`
	Connections []ConnectionsSummary `json:"connections,omitempty"`

Node is the data type that's yielded to the JavaScript layer when we want deep information about an individual node.

func CensorNode added in v1.11.0

func CensorNode(node Node, cfg report.CensorConfig) Node

CensorNode removes any sensitive data from a node.

func MakeNode

func MakeNode(topologyID string, rc RenderContext, ns report.Nodes, n report.Node) Node

MakeNode transforms a renderable node to a detailed node. It uses aggregate metadata, plus the set of origin node IDs, to produce tables.

type NodeSummaries added in v0.14.0

type NodeSummaries map[string]NodeSummary

NodeSummaries is a set of NodeSummaries indexed by ID.

func CensorNodeSummaries added in v1.11.0

func CensorNodeSummaries(summaries NodeSummaries, cfg report.CensorConfig) NodeSummaries

CensorNodeSummaries removes any sensitive data from a list of node summaries.

func Summaries added in v0.14.0

func Summaries(ctx context.Context, rc RenderContext, rns report.Nodes) NodeSummaries

Summaries converts RenderableNodes into a set of NodeSummaries

type NodeSummary

type NodeSummary struct {
	Metadata  []report.MetadataRow `json:"metadata,omitempty"`
	Parents   []Parent             `json:"parents,omitempty"`
	Metrics   []report.MetricRow   `json:"metrics,omitempty"`
	Tables    []report.Table       `json:"tables,omitempty"`
	Adjacency report.IDList        `json:"adjacency,omitempty"`

NodeSummary is summary information about a Node.

func MakeNodeSummary

func MakeNodeSummary(rc RenderContext, n report.Node) (NodeSummary, bool)

MakeNodeSummary summarizes a node, if possible.

func RenderMetricURLs added in v1.6.3

func RenderMetricURLs(summary NodeSummary, n report.Node, r report.Report, metricsGraphURL string) NodeSummary

RenderMetricURLs sets respective URLs for metrics in a node summary. Missing metrics where we have a query for will be appended as an empty metric (no values or samples).

func (NodeSummary) SummarizeMetrics added in v0.14.0

func (n NodeSummary) SummarizeMetrics() NodeSummary

SummarizeMetrics returns a copy of the NodeSummary where the metrics are replaced with their summaries
