A URL-safe Base64-encoded (RFC 4648, no padding) token encoding the tracker's identity. Pass this token to LDGraphTrackerImpl.fromResumptionToken to reconstruct the tracker across process boundaries, preserving the original runId.
Security note: The token contains the flag variation key and version. If passed to an untrusted client (e.g., a browser) this could expose feature-flag targeting details. Keep the token server-side and use an opaque reference in client-facing APIs.
Returns a snapshot of all graph-level metrics tracked so far. Fields
populate incrementally as track* methods are called, so the result is
a Partial<LDAIGraphMetricSummary>. Once the graph run has
completed via ManagedAgentGraph.run(), prefer ManagedGraphResult.metrics
which is fully populated.
Returns tracking metadata to be included in every LDClient.track call.
Tracks the total duration of the graph run in milliseconds.
Emits event $ld:ai:graph:duration:total with the duration as the metric value.
At-most-once: subsequent calls are dropped with a warning.
Duration in milliseconds.
Tracks a failed handoff between two nodes.
Emits event $ld:ai:graph:handoff_failure with metric value 1.
Config key of the source node.
Config key of the target node.
Tracks a successful handoff between two nodes.
Emits event $ld:ai:graph:handoff_success with metric value 1.
Config key of the source node.
Config key of the target node.
Tracks an unsuccessful graph run.
Emits event $ld:ai:graph:invocation_failure with metric value 1.
At-most-once: subsequent calls are dropped with a warning.
Tracks a successful graph run.
Emits event $ld:ai:graph:invocation_success with metric value 1.
At-most-once: subsequent calls are dropped with a warning.
Tracks the path taken through the graph during this run.
Emits event $ld:ai:graph:path with metric value 1.
The data payload includes the path array in addition to standard track data.
At-most-once: subsequent calls are dropped with a warning.
An ordered array of agent config keys representing the path taken.
Tracks when a node redirects to a different target than originally specified.
Emits event $ld:ai:graph:redirect with metric value 1.
Config key of the source node.
Config key of the actual target node.
Tracks aggregate token usage across the entire graph run.
Emits event $ld:ai:graph:total_tokens with the total token count as the metric value.
At-most-once: subsequent calls are dropped with a warning.
Token usage information.
StaticfromReconstructs an LDGraphTrackerImpl from a resumption token, preserving
the original runId so all events continue to be correlated under the same run.
Security note: The token contains the flag variation key and version. Do not pass the raw token to untrusted clients.
URL-safe Base64-encoded token produced by LDGraphTrackerImpl.resumptionToken.
LaunchDarkly client instance.
LDContext for the new tracker.
Concrete implementation of LDGraphTracker.
Construct directly or reconstruct from a resumption token via LDGraphTrackerImpl.fromResumptionToken.
