Javabrake

.github/workflows/test.yml

Introduction

Javabrake is a Java notifier for Airbrake.

Installation

Gradle:

implementation 'io.airbrake:javabrake:0.3.0'

Maven:

<dependency>
  <groupId>io.airbrake</groupId>
  <artifactId>javabrake</artifactId>
  <version>0.3.0</version>
</dependency>

Ivy:

<dependency org='io.airbrake' name='javabrake' rev='0.3.0'>
  <artifact name='javabrake' ext='pom'></artifact>
</dependency>

Quickstart

Configuration:

import io.airbrake.javabrake.Notifier;
import io.airbrake.javabrake.Config;

Config config = new Config();
config.projectId = 12345;
config.projectKey = "FIXME";
Notifier notifier = new Notifier(config);

notifier.addFilter(
    (Notice notice) -> {
      notice.setContext("environment", "production");
      return notice;
    });

Error Monitoring

Sending errors to Airbrake

Using notifier directly

try {
  do();
} catch (IOException e) {
  notifier.report(e);
}

Using Airbrake proxy class

import io.airbrake.javabrake.Airbrake;

try {
  do();
} catch (IOException e) {
  Airbrake.report(e);
}

Sending errors synchronously

By default report sends errors asynchronously returning a Future, but synchronous API is also available:

import io.airbrake.javabrake.Notice;

Notice notice = Airbrake.reportSync(e);
if (notice.exception != null) {
    logger.info(notice.exception);
} else {
    logger.info(notice.id);
}

Adding custom params

To set custom params you can build and send notice in separate steps:

import io.airbrake.javabrake.Notice;

Notice notice = Airbrake.buildNotice(e);
notice.setContext("component", "mycomponent");
notice.setParam("param1", "value1");
Airbrake.send(notice);

You can also set custom params on all reported notices:

notifier.addFilter(
    (Notice notice) -> {
      notice.setParam("myparam", "myvalue");
      return notice;
    });

Linking errors to routes

You can link error notices with the routes by setting the route e.g. /hello and httpMethod e.g. GET, POST in the custom parameters for error notices. For example:

Notice notice = notifier.buildNotice(e);
notice.setContext("route", "route-name");
notice.setContext("httpMethod", "http-method-name");

Ignoring notices

gnore specific notice:

notifier.addFilter(
    (Notice notice) -> {
      if (notice.context.get("environment") == "development") {
          // Ignore notice.
          return null;
      }
      return notice;
    });

Debugging notices

To debug why notices are not sent you can use onReportedNotice hook:

notifier.onReportedNotice(
    (notice) -> {
      if (notice.exception != null) {
        logger.info(notice.exception);
      } else {
        logger.info(String.format("notice id=%s url=%s", notice.id, notice.url));
      }
    });

Performance Monitoring

You can read more about our Performance Monitoring offering in our docs.

Sending route stats

notifier.routes.notify allows sending route stats to Airbrake. You can also use this API manually:

import io.airbrake.javabrake.RouteMetric;

RouteMetric metric = new RouteMetric(request.getMethod(), request.getRequestURI());
metric.statusCode = response.getStatus();
metric.contentType = response.getContentType();
metric.endTime = new Date();

notifier.routes.notify(metric);

Sending route breakdowns

notifier.routes.notify allows sending performance breakdown stats to Airbrake. You can use this API manually:

import io.airbrake.javabrake.RouteMetric;

RouteMetric metric = new RouteMetric(request.getMethod(), request.getRequestURI());

metric.startSpan("span1 name", new Date());
try {
	do();
} catch (Exception e) {
	e.printStackTrace();
}
metric.endSpan("span1 name", new Date());

metric.startSpan("span2 name", new Date());
try {
  do();
} catch (Exception e) {
	e.printStackTrace();
}
metric.endSpan("span2 name", new Date());		
metric.end();

metric.statusCode = response.getStatus();
metric.contentType = response.getContentType();

notifier.routes.notify(metric);

Sending query stats

notifier.queries.notify allows sending SQL query stats to Airbrake. You can also use this API manually:

Date startTime = new Date();
try
{
  do();
}catch(
Exception e)
{
  e.printStackTrace();
}
Date endTime = new Date();

notifier.queries.notify(request.getMethod(),request.getRequestURI()
,"SELECT * FROM foos",startTime,endTime);

Sending queue stats

notifier.queues.notify allows sending queue (job) stats to Airbrake. You can also use this API manually:

import io.airbrake.javabrake.QueueMetric;

QueueMetric metric = new QueueMetric("foo_queue");

metric.startSpan("span1 name", new Date());
try {
    do();
} catch (Exception e) {
    e.printStackTrace();
}
metric.endSpan("span1 name", new Date());

metric.startSpan("span2 name", new Date());
try {
  do();
} catch (Exception e) {
  e.printStackTrace();
}
metric.endSpan("span2 name", new Date());
metric.end();

notifier.queues.notify(metric);

HTTP proxy

javabrake uses OkHttp as an HTTP client. So in order to use proxy all you have to do is to configure OkHttpClient:

import java.net.InetSocketAddress;

import okhttp3.OkHttpClient;
import okhttp3.Proxy;

import io.airbrake.javabrake.OkSender;

Proxy proxy = new Proxy(Proxy.Type.HTTP, InetSocketAddress.createUnresolved("192.168.1.105", 8081);
OkHttpClient httpClient =
    new OkHttpClient.Builder()
        .connectTimeout(3000, TimeUnit.MILLISECONDS)
        .readTimeout(3000, TimeUnit.MILLISECONDS)
        .writeTimeout(3000, TimeUnit.MILLISECONDS)
        .proxy(proxy)
        .build();
OkSender.setOkHttpClient(httpClient);

Notifier release instrucitons

A note on Java version

Make sure you build and release this notifier with open-jdk-8, one way to manage your local java version is using asdf. You can install this tool via homebrew:

brew install asdf

Then install open-jdk-8 and set it as JAVA home before running any of the ./gradlew commands:

asdf plugin add java
asdf install java adoptopenjdk-8.0.312+7
export JAVA_HOME=$HOME/.asdf/installs/java/adoptopenjdk-8.0.312+7

Build

./gradlew build

Upload to JCentral:

./gradlew bintrayUpload

Upload to Maven Central:

./gradlew uploadArchives
./gradlew closeAndReleaseRepository
