REST Monitoring in Payara Server

The Payara Server 173 release included a technical preview of the REST Monitoring Service, which is a service to expose JMX monitoring MBeans over HTTP. As of Payara Server 174, this feature is no longer in tech preview.

One big problem with JMX is that JMX monitoring uses RMI (Remote Method Invocation), which can lead to a few nightmares if, for example, you have a firewall which blocks connections over RMI ports. The REST monitoring service in Payara Server now provides a service which will be very familiar to users of Jolokia in that it makes this monitoring data available over HTTP, making the data available in a more standard format (JSON) and accessible over a standard HTTP connection.

Using Hibernate 5 on Payara Server

Hibernate is the object/relational mapping tool that handles mapping of Java classes to relational tables and Java types to SQL data type. It’s a well-known framework in the Enterprise Java eco-system since it’s being actively developed for the last 16 years.

With this article, I’m going to show the ways of using Hibernate inside a sample application – source code available here – and deploy it onto Payara Server. I will be using the latest version of Hibernate, which is 5.2.10.Final at the time of writing.

Request Tracing Service in Payara Server & Payara Micro

Have you ever wondered whether your application is slow to respond to requests? Which requests take the longest to respond to? And what you can do about it? Payara Server aims to provide the best tooling you would need to identify performance issues, identify their causes and help you solve them. One part of this tooling is the new Request Tracing service, available in Payara Server and Payara Micro from version 163 as a technical preview.

 

Payara Server in Production - Quick Tip

TIP: Don't deploy any apps to the DAS in production!

Why?

As is the case with all my stories, this one began at a customer site. They had an old app they were migrating from GlassFish 3.1.2 to the latest version of Payara Blue. They'd called me in because they wanted to benchmark performance of the new version of Payara Blue on AIX against their existing GlassFish 3.1.2, also on AIX, as well as against a recent version of JBoss (I'm unsure of the version, though I know it was deployed on Windows).

What's new in Payara Server 163?

As we enter the third quarter of the year, that can only mean one thing: Payara Server 163 is here! With this release, we’ve managed to cram in 44 bug fixes, 34 enhancements, 6 new features and 6 component upgrades. One of these new features is the tech preview of our new Request Tracing service, which I’ll explain in more detail below.
