Metrics are enabled but no global MeterProvider is configure

Error message

Metrics are enabled but no global MeterProvider is configured.

Set up OpenTelemetry before initializing redis-py observability:

  from opentelemetry import metrics
  from opentelemetry.sdk.metrics import MeterProvider
  from opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader
  from opentelemetry.exporter.otlp.proto.http.metric_exporter import OTLPMetricExporter

  # Create exporter
  exporter = OTLPMetricExporter(
      endpoint='http://localhost:4318/v1/metrics'
  )

  # Create reader
  reader = PeriodicExportingMetricReader(
      exporter=exporter,
      export_interval_millis=10000
  )

  # Create and set global provider
  provider = MeterProvider(metric_readers=[reader])
  metrics.set_meter_provider(provider)

  # Now initialize redis-py observability
  from redis.observability import get_observability_instance, OTelConfig
  otel = get_observability_instance()
  otel.init(OTelConfig(enable_metrics=True))
