Robust management and monitoring is a key value proposition for modern Java EE application servers that most developers seem to be unaware of. Fortunately this is changing rapidly as more and more developers get exposed to operations concerns via the DevOps movement.
GlassFish has never been a slouch when it comes to management and monitoring (although an application server like WebLogic truly excels in this area). GlassFish has long provided many ways for management and monitoring including the admin console GUI, the asadmin command-line tool, a REST admin interface and JMX. If you don't know about these features as a GlassFish user, you owe it to yourself to learn a bit more about it.
A golden opportunity for this was recently organized by our friends at the London GlassFish User Group. On March 6th they organized an excellent virtual event with celebrated Java EE advocate, author, JCP expert and Java Champion Adam Bien on GlassFish management and monitoring. Fortunately for all of us, the event was recorded and you can check out the video below:
Much of the material covered in the talk is also covered in a recent OTN article that Adam wrote - it might be easier to use as a reference.
