JMX

Summary

The JMX collector uses Jolokia to collect data on your MBeans. Jolokia is an agent that provides access to JMX MBeans without having to write any Java code. Netuitive can be used to process and graph the data collected by Jolokia. This can be useful if you'd like to collect a small set of metrics via JMX e.g., garbage collection metrics on your Cassandra cluster.

Java Integration Options

We have several different options for monitoring Java applications. Each method varies in terms of setup difficulty and the amount / type of information it collects. See the table below for more information.

Method Description
Ananke

Java library you can use to push metrics to the StatsD listener embedded in our Linux agent.

Important   This approach requires that you integrate the StatsDReporter into your applications.
Dropwizard

Integrate the dropwizard-metrics library into your Dropwizard application and either configure it to send metrics to the StatsD listener embedded in our Linux agent or directly to Netuitive's REST API.

Iris Java library you can use to push metrics directly to Netuitive's REST API.
Java Agent Open-source and open-license Java agent the does the byte-code instrumentation for you. No changes to source code required.
JMX Integration that relies on our Linux agent to collect JVM metrics (e.g., heap size, garbage collection, etc.) without code-level instrumentation.

Configuration

Important   If you haven't installed the Linux agent already, see the instructions on this page for how to install it. If you need to disable the Linux integration or view the unique API key assigned to your account, navigate to the Integrations page under the user account drop-down menu and click the integration designated as Infrastructure under the Integration column.

Collector Configuration

  1. Download the Jolokia JVM JAR file.
    1. Move the downloaded file to the /opt/netuitive-agent/ directory.
    2. Pass the Java agent parameter into your application.
      -javaagent:/opt/agent.jar=port=8778,host=0.0.0.0
  2. Navigate to the collectors folder.
    Note   The default location is /opt/netuitive-agent/conf/collectors.
  3. Open the JolokiaCollector.conf file.
    Note   This configuration file will only be available in agent versions 0.3.1 or later. Otherwise, you will have to create a configuration file with the same name.
  4. Change the enabled setting to True.
  5. Save the configuration file, and restart the Linux Agent.
