Package com.google.genkit.ai.telemetry

Class GenerateTelemetry

java.lang.Object

com.google.genkit.ai.telemetry.GenerateTelemetry

public class GenerateTelemetry
extends Object

GenerateTelemetry provides metrics collection for model generate actions.

This class tracks:

• Request counts per model
• Latency histograms
• Input/output token counts
• Input/output character counts
• Input/output image counts

The metrics follow the same naming conventions as the JS and Go SDKs for consistency across the Genkit ecosystem.

Meters are obtained lazily from GlobalOpenTelemetry to ensure they use the correct MeterProvider when telemetry plugins (like Firebase) are initialized.
