Java Code Performance Monitoring

[khalil]

Using Zabbix, is there a means to instrument/measure the performance of a Java application component ? For instance, I would like to:
1. Measure the response time of some Java classes.methods
2. Report the gathered metrics to Zabbix server
3. Visualize them in dashboards
Many thanks in advance for your support.

Can you make modifications the application code? If so, I would suggest looking at libraries such as Yammer Metrics or Netflix Servo. Personally I use Yammer Metrics and you can simply create a new timer, time a section of code, and the metric will be available via JMX. Then in Zabbix just collect this information via JMX, put the collected items for a particular timer into its own Zabbix graph. For instance at my company we collect the Yammer Metrics timer percentiles every 5 minutes which allows for us to see changing trends in execution times (this uses a biased histogram for timings which you can read about in the Metrics documentation) - then you can also collect the standard aggregate information such as min/max/avg etc.

Many thanks for the provided links. Unfortunately, the application code is a black box for me and I can't modify the source code. I would prefer another alternative to source code modification using dynamic Java byte code instrumentation/injection techniques or tools providing this functionality and that could be integrated within Zabbix.

Thank you for your reply and support.
