Monitoring datasource connection pool on Wildfly9

Question

I'm working on the project where I'm trying to get the runtime statistics of my datasource connection pool which I placed into /deployment folder using Wildfly-9. I searched for it and I found the configuration file which exist inside /standalone folder named as standalone.xml file giving me the statistics of datasource connection poool by using below code :

<datasource jta="true" jndi-name="java:jboss/datasources/DemoDS" pool-name="DemoDS" enabled="true" use-ccm="true" statistics-enabled="true">
    <connection-url>jdbc:mysql://localhost:3306/demo?zeroDateTimeBehavior=convertToNull</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
        <driver>mysql</driver>
        <pool>
            <min-pool-size>1</min-pool-size>
            <max-pool-size>50</max-pool-size>
        </pool>
        <security>
            <user-name>root</user-name>
            <password>root</password>
        </security>
    <validation>
        <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
        <background-validation>true</background-validation>
        <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
    </validation>
</datasource>

Hit this url I got this:

http://localhost:9990/management/subsystem/datasources/data-source/DemoDS/statistics/pool?include-runtime=true

I get the following json string: You get the following json string:

}

Since I have many datasource file I cannot place into individual standalone.xml file. So anyone knows how I will get the runtime statistics of my datasource connection pool which I placed into /deployment folder?

From Wildfly CLI:

Check if stats enabled for datasource

/subsystem=datasources/data-source=(your datasourcename):read-attribute(name=statistics-enabled)  

Enable stats: requires restart of Wildfly service afterwards

/subsystem=datasources/data-source=(your datasource):write-attribute(name=statistics-enabled, value=true) 

After restart start CLI and run the check command again.
