JMX extension - JBoss Connection Pools

a_chiaravalle — Tue, 01 Apr 2025 08:23:16 GMT

Does anyone have documentation about these JBoss Connection Pools metrics ?:

- Total pool time

- Total get time

- Total usage time

I searched in jboss documentation and I found the following, but nothing about the previous ones:

https://access.redhat.com/documentation/it-it/jboss_enterprise_application_platform/6.3/html/administration_and_configuration_guide/datasource_statistics

thanks

Hi Anton

In this document I found just the following, without any metric description:

Metric name Metric key Description Unit

Total blocking time	jboss.connectionPool.TotalBlockingTime.count	-	MilliSecond
Total creation time	jboss.connectionPool.TotalCreationTime.count	-	MilliSecond
Total pool time	jboss.connectionPool.TotalPoolTime.count	-	MilliSecond
Total get time	jboss.connectionPool.TotalGetTime.count	-	MilliSecond
Total usage time	jboss.connectionPool.TotalUsageTime.count	-	MilliSecond

Thanks and regards

I found some descriptions in a different RedHat doc page: https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.2/html-single/performance_tuning_guide/index

Total pool time: The total time spent by connections in the pool.
Total get time: The total time spent obtaining connections.
Total usage time: The total time spent using connections.

Note that in Dynatrace these are being reported as 'counter' metrics so the number you'll see is the delta/change from the previous interval as opposed to the constantly growing value you'd see if you checked these values yourself.
