16.2. Tracing

This feature is available only in Redisson PRO

Redisson provides integration with the most popular tracer libraries through Micrometer Observation API and Micrometer Tracing framework. This feature allows to gather extra statistics about invoked Redisson methods: name, arguments, invocation path, duration and frequency.

Configuration metrics per Tracing event.

  • invocation - Redisson method with arguments. Arguments are included only if includeArgs set true
  • object_name - Redisson object name
  • address - Redis server address
  • username - username used to connect to Redis server

1. OpenZipkin Brave

OkHttpSender sender = OkHttpSender.create("http://localhost:9411/api/v2/spans");
AsyncZipkinSpanHandler zipkinSpanHandler = AsyncZipkinSpanHandler.create(sender);
StrictCurrentTraceContext braveCurrentTraceContext = StrictCurrentTraceContext.create();

Tracing tracing = Tracing.newBuilder()
                         .localServiceName("myservice")
