Haystack Client Java

Haystack client java is an OpenTracing compatible library which is used to capture information about distributed operations and report them to haystack

Opentracing API usage has been documented at https://github.com/opentracing/opentracing-java.

OpenTracing version compatibility

The current OpenTracing version 0.33 has introduced backwards incompatible changes with all previous versions. Please make sure that your dependencies on OpenTracing align to the 0.33 version to avoid runtime issues.

Examples

You can look at our sample projects for how to trace a simple web application

• SpringBoot Example
• Dropwizard Example

Core Modules

haystack-client-core - library provides an implementation of io.opentracing.Tracer that sends spans to Haystack server.

Addon Modules

haystack-client-metrics-micrometer: metrics provider backed by micrometer, to report internal Haystack Client metrics to third-party backends, such as Prometheus

haystack-client-metrics-dropwizard: metrics provider backed by dropwizard-metrics, to report internal Haystack Client metrics to third-party backends, such as Graphite

haystack-client-metrics-api: metrics api consumed by haystack-client-core to report internal Haystack Client metrics. By default its bundled with a NoOp metrics dispatcher, add any of the obove dependencies to push the client metrics.
