java - 监控Wildfly9上的数据源连接池

Question

我正在开发一个项目，试图获取我使用 Wildfly-9 放入/deployment 文件夹中的数据源连接池的运行时统计信息。我搜索了它，发现/standalone 文件夹中存在名为standalone.xml 文件的配置文件，通过使用以下代码为我提供数据源连接池的统计信息:

<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>

点击这个网址我得到了这个:

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

我得到以下 json 字符串:您将得到以下 json 字符串:

   "XAStartMaxTime":0,

}

由于我有许多数据源文件，我无法将其放入单独的standalone.xml 文件中。那么有人知道我如何获取我放入/deployment 文件夹中的数据源连接池的运行时统计信息吗？

来自 Wildfly CLI:

检查数据源是否启用统计

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

启用统计信息:之后需要重新启动 Wildfly 服务

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

重启后启动 CLI 并再次运行检查命令。
