Overview

zconstants are special span/event tags that provide context for span transformation in the frontend storage plugin.

Constants

View Source
const (
	LinkedObjectCluster   = "linkedCluster"
	LinkedObjectGroup     = "linkedGroup"
	LinkedObjectResource  = "linkedResource"
	LinkedObjectNamespace = "linkedNamespace"
	LinkedObjectName      = "linkedName"

	// Indicates how the linked trace interacts with the current trace.
	LinkRole = "linkRole"

	// If this tag is nonempty, a virtual span is inserted between the linked objects with the tag value as the name.
	LinkClass = "linkClass"
)

Tags for TraceSourceLink spans that indicate the linked object.

View Source
const (
	TraceSourceObject = "object"

	TraceSourceAudit = "audit"
	TraceSourceEvent = "event"
)
View Source
const DummyDuration = time.Second

DummyDuration is the span duration used when the span is instantaneous.

View Source
const LogTypeAttr = Prefix + "logType"

Classifies the type of a log line. Logs without this attribute will not have special treatment.

View Source
const NotPseudo = Prefix + "notPseudo"

Indicates that the current span is not pseudo. Used to optimize trace listing.

This constant is used as both tag key and value.

View Source
const Prefix = "zzz-"

All tags with this prefix are not rendered.

View Source
const PseudoType = Prefix + "pseudoType"

Indicates that the current span is a pseudospan that can be folded or flattened. The value is the folding type.

View Source
const SpanName = Prefix + "kelemetryName"

The value replaces the OperationName.

View Source
const TraceSource = Prefix + "traceSource"

Identifies that the span represents an actual event (rather than as a pseudospan).
