Number of open connections in pool

Question

Hi,
I want to find out how many connections are being used from my connection pool. From the monitoring capabilities you can only know the numer of timed-out connections, threads waiting and connections which failed validation.
How can i know the number of used connections?.
And too, can i monitorize the openning of the connections, the closure, when it is asigned to another thread, freed, etc.
Thanks
Juan

Hi,
I have been using the same for the last 6 months on UR1, UR2 and even on SJS8 without any issues. All works fine. The setting in my case is like this:
<jvm-options>-DMONITOR_JDBC=true</jvm-options>
    <jvm-options>-DMONITOR_TIME_PERIOD_SECONDS=60</jvm-options>
    <jvm-options>-DMONITOR_JDBC_TIME_PERIOD_SECONDS=60</jvm-options>But note that just having this setting in the JVM options is not enough. In the connection pool that you wish to monitor, you need to add one more property as follows:
<property value="true" name="perf-monitor"/>This will make the connection pool available for monitoring. If yous wish to turn it off, all you need to do is to turn perf-monitor value to false.
There is one other way to monitor the connection pool though. This can be done on the system level. The way to do it is as follows:
asadmin get --user <appservadmin user> --password <appservadmin password> --port <admin server port> --monitor <instance name>.resources.jdbc-connection-pool.<JDBC Connection pool name>.*To monitor the transactions, you can use this:
asadmin get --user <appservadmin user> --password <appservadmin password> --port <admin server port> --monitor <instance name>.transaction-service.*Hope this is of help.
