Exploring JIRA 7.6: Live monitoring with JMX

With the latest release of Jira just out, some exciting new features were added; among them is the addition of JMX Live Monitoring, which allows you to monitor your JIRA instance in real time. This is seriously helpful, as you can check the number of requests your Jira has to manage, the total response time, details about your license and even the number of issues your users have created.

Let’s take a look as to how this works:

Wait, what is JMX?

JMX stands for Java Management Extensions, an API that lets you manage and monitor JAVA applications and services, using objects called MBeans (Managed Beans).
It exposes your JVM underlying data and resources, enabling you to easily monitor your instance(s) and make more informed decisions to optimize and maintain them.

Most importantly, these resources are live and can help in troubleshooting or audit scenarios, or to help you diagnose pain points instantly.

The latest release of Jira 7.6 adds a new System property, where you can easily toggle the functionality on or off:

 

Accessing data

To access live diagnostics, you can use jconsole. You can monitor your instance locally or remotely, but a remote execution is preferred as it does not impact your Jira server. The different tabs list all the available stats, and you can perform various operations, such as Garbage Collection, or set different timeframes.

 

Memory

As well as selecting time ranges, you can select different types of memory pools or use the Heap/Non-Heap dashboard on the bottom right-hand corner to click on values directly.

 

Threads

Many live threads are available and offer insights into your environment, such as detecting deadlocks and obtaining stack traces (These features were previously available, though could not be toggled directly from the UI as is now the case).

 

MBeans

The new functionality introduced with 7.6 is the availability of Jira specific statistics (the “MBeans”) and can be accessed from the jconsole MBeans tab under com.atlassian.Jira:

 

 

The BasicDataResource component lists all your database information in one handy panel, from url to username, password and other db settings:

 

 

The other attributes listed in the table above can help tremendously in a situation where you need to quickly size your implementation and find out how many users, issues, filters were created. It offers a one-stop solution to not only gather server statistics, but also information specific to your Jira environment such as projects, components or groups.

Here is the official list of components Atlassian has made available:
