LangfuseMetricsQuery

NexusLabs.Needlr.AgentFramework.Langfuse

LangfuseMetricsQuery Class

A query against the Langfuse Metrics API (GET /api/public/metrics). Use it to read aggregates back from Langfuse — for example to drive a CI quality gate from recorded eval scores.

public sealed record LangfuseMetricsQuery : System.IEquatable<NexusLabs.Needlr.AgentFramework.Langfuse.LangfuseMetricsQuery>

Inheritance System.Object 🡒 LangfuseMetricsQuery

Implements System.IEquatable<LangfuseMetricsQuery>

Remarks

Langfuse ingests asynchronously, so freshly recorded data may take a few seconds to appear in metrics. Flush and allow for ingestion lag before asserting on results.
