  • public class OpenTelemetryResolver
extends java.lang.Object
    Resolver class for OpenTelemetry operations in Valkey GLIDE. This class provides native methods to interact with OpenTelemetry functionality implemented in the Rust core library.

      Modifier and Type Method Description
      static long createLeakedOtelSpan​(java.lang.String spanName)
      Creates a new OpenTelemetry span with the given name that will not be automatically dropped by the Rust core.
      static void dropOtelSpan​(long spanPtr)
      Drops an OpenTelemetry span that was created with createLeakedOtelSpan(String), releasing its resources.
      static int initOpenTelemetry​(java.lang.String tracesEndpoint, int tracesSamplePercentage, java.lang.String metricsEndpoint, long flushIntervalMs)
      Initializes OpenTelemetry with the provided configuration.

      • initOpenTelemetry

        public static int initOpenTelemetry​(java.lang.String tracesEndpoint,
                                    int tracesSamplePercentage,
                                    java.lang.String metricsEndpoint,
                                    long flushIntervalMs)
        Initializes OpenTelemetry with the provided configuration.
        Parameters:
        tracesEndpoint - The endpoint for traces exporter (can be null if not used)
        tracesSamplePercentage - The percentage of requests to sample (0 for default)
        metricsEndpoint - The endpoint for metrics exporter (can be null if not used)
        flushIntervalMs - The interval in milliseconds between consecutive exports (0 for default)
        Returns:
        0 on success, error code otherwise: 1 - Missing configuration (both traces and metrics are null) 2 - Invalid traces endpoint 3 - Invalid metrics endpoint 4 - Runtime initialization failure 5 - OpenTelemetry initialization failure

      • createLeakedOtelSpan

        public static long createLeakedOtelSpan​(java.lang.String spanName)
        Creates a new OpenTelemetry span with the given name that will not be automatically dropped by the Rust core. The caller is responsible for dropping this span using dropOtelSpan(long).
        Parameters:
        spanName - The name of the span to create
        Returns:
        A pointer to the created span, or 0 if creation failed

      • dropOtelSpan

        public static void dropOtelSpan​(long spanPtr)
        Drops an OpenTelemetry span that was created with createLeakedOtelSpan(String), releasing its resources.
        Parameters:
        spanPtr - The pointer to the span to drop
