#28596 — Java monitor

I deployed my app into my production server and now I'd like to monitor it 
to check memory, resources used , etc

Any idea?

I'm using JVisualVM (inside JDK) but I need something better..

Info I'd like to monitor:

- number of classes loaded and threads running
- Java VM uptime, system properties, and VM input arguments
- threads
- memory consumption
- garbage collection stat
- low memory detection
- on-demand deadlock detection
...

What does "better" mean? IOW: what are you missing in jvisualvm?

Cheers

Even if you enlarge the period of observation, you can't have all the time 
you want and moreover you can't store data collected.. (for example)

And I was curious to know if there was a better software, if servers of big 
companies are monitored by JVisualVM or any other more professional 
monitor..

If you want to record, there is jstat and options to write a GC log. 
And you can query various JMX beans.  So a lot is available via tools 
coming with the JRE / JDK.  And you'd be surprised how many enterprises 
use custom monitoring solution... :-)  Having said that there are 
probably tools around that promise professional monitoring of Java 
applications.

Kind regards

I wouldn't overlook doing your own logging and reading log files.  If 
you're interested in specific things, logging might be the best.  Even 
if not, a good general suit of logs is a useful thing for any application.
