The Health Check Service In-Depth - Payara Server 5

This is an updated blog of the original which was published in May 2016

Payara Server provides the Health Check Service for automatic self-monitoring in order to detect future problems as soon as possible. When enabled, the Health Check Service periodically checks some low level metrics. Whenever it detects that a threshold is not met, it triggers alert notifications that allow to detect undesired behavior and predict possible failures. All of these automatic checks are very lightweight and run with a negligible impact on performance.

New Feature of Payara Platform 5.184: Automated Health Check Checker

There has been a lot of noise around MicroProfile for quite a while now, and one of the specs provided by MicroProfile are Health Checks. The aim of this spec is to allow you to write a number of health checks that will run when you hit a specific endpoint, the intention being that this endpoint can be periodically poked by a container orchestrator to determine if an instance is responsive and healthy.

Introducing the Stuck Threads HealthCheck in Payara Server 173

Since being introduced in the 163 release, the Request Tracing Service has allowed you to see which requests are taking a long time. However, this service will only tell you about requests once they have completed. If a thread is stuck and unable to complete you will not know about it. To resolve that problem, we added the Stuck Threads HealthCheck to Payara Server, which checks for requests that have not finished and outputs their stack trace.

The HealthCheck Service In-Depth - Payara Micro

The HealthCheck Service provides automatic self-monitoring in order to detect future problems as soon as possible. The HealthCheck Service was introduced in Payara Server and Payara Micro version 161 and some new metrics have been added in version 162.

All the functionality of the HealthCheck Service that is available in Payara Server is also included in Payara Micro. However, as Payara Micro differs in some concepts from Payara Server, the usage and configuration of the HealthCheck Service is slightly different. In this post, we will focus on how to use it in Payara Micro.
