JarCastingOpenTracing Grizzly Async HTTP Client Instrumentation
OpenTracing instrumentation for Grizzly Async HTTP Client.
OpenTracing Agents
When using a runtime agent like java-agent or java-specialagent AsyncHttpClients will be automatically instrumented by injecting a TracingRequestFilter into its AsyncHttpClientConfig. This is the case with the plain AsyncHttpClient or SimpleAsyncHttpClient:
AsyncHttpClient client = new AsyncHttpClient();
Response response = client.prepareGet("http://localhost:8080/root").execute().get();
or
SimpleAsyncHttpClient client = new SimpleAsyncHttpClient.Builder()
.setUrl("http://localhost:8080/root")
.build();
Response respose = client.get().get();
Refer to the agents' documentation for how to include this library as an instrumentation plugin.
Non-Agent Configuration
When not using any of the OpenTracing Agents the TracingRequestFiler must be added directly to the AsyncHttpClientConfig.
AsyncHttpClientConfig config = new AsyncHttpClientConfig.Builder()
.addRequestFilter(new TracingRequestFilter())
.build();
AsyncHttpClient client = new AsyncHttpClient(config);
