# Lightstep Java Metrics Reporter

[ ![Download](https://img.shields.io/maven-central/v/com.lightstep.tracer/java-metrics-reporter.svg)](http://search.maven.org/#search%7Cga%7C1%7Ccom.lightstep.tracer%20java-metrics-reporter) [![Circle CI](https://circleci.com/gh/lightstep/lightstep-metrics-java.svg?style=shield)](https://circleci.com/gh/lightstep/lightstep-metrics-java)

This library automatically reports a set of predefined host metrics

(such as CPU and memory usage) to the Lightstep backend.

Java 8 or newer is required. When running Java 7, no metrics reporting

will be performed.

Note: Using this artifact requires tracing being done in the same process

and sharing the same service name/version and access token. If not done,

the reported metrics will be ignored at the backend.

### Maven

```xml

   com.lightstep.tracer

   java-metrics-reporter

   VERSION

```

### Usage

```java

import com.lightstep.tracer.metrics.Metrics;

import com.lightstep.tracer.metrics.OkHttpSender;

import com.lightstep.tracer.metrics.Sender;

...

  // Done once, at application initialization.

  Sender,?> sender = new OkHttpSender(

      "MyServiceName", // Service/Component name.

      "MyAccessToken", // Access Token. Nullable

      "1.2.3", // Service version. Nullable

      "https://" // Metrics url

      30000 // connect timeout in milliseconds

  );

  // Metrics inherits from Thread.

  Metrics metrics = new Metrics(

      sender, 

      30 // sample period in seconds

  );

  metrics.setDaemon(true);

  metrics.start();

  // Done at application/reporter shutdown.

  metrics.close();

```
