I've research how to monitor connection pool on Tomcat server. After research I found this question.

Per his answer, I choose option 2 - Monitoring using JMX (Java Management Extensions). I try to set up JMX on Tomcat server and finally, I can remote to monitor Memory usage, CPU usage, Thread pool and Loaded classes.

However, I couldn't monitor the connection pool because the org.apache.tomcat.jdbc.pool.jmx in the MBeans tab is missing. (I should be like this expected picture but I got this actual picture)

So, is there any way to montitor connection pool by using JConsole or could anyone can help answer me why org.apache.tomcat.jdbc.pool.jmx doesn't show on JConsole?

Thanks.

The reason why org.apache.tomcat.jdbc.pool.jmx didn't show in JConsole is right now we didn't use JDBC anymore. Sorry for my misunderstanding.

I can monitor numActive, numIdle of the connection pool by using JConsole (it's appear in MBean section and the path is Tomcat/Datasource/localhost/javax.sql.DataSource/name-of-datasource/Attributes).

However, the chart of numActive and numIdle does not maintain historical data.

After researching, I found this http://www.testautomationguru.com/jmx-monitoring-using-collectd-influxdb-grafana/ it said we have to use another plug-in to collect data and visualize it. So, I try to setup these tools and finally it works!

Thanks.
