红帽全球峰会12.11.2. 查看数据源统计信息
您可以使用管理 CLI 或管理控制台查看数据源的运行时统计信息。
使用管理 CLI 查看数据源统计信息
以下管理 CLI 命令检索 ExampleDS 数据源的核心 池 统计信息：
注意
在受管域中，在这些命令前加上 /host=HOST_NAME/server=SERVER_NAME。
/subsystem=datasources/data-source=ExampleDS/statistics=pool:read-resource(include-runtime=true)
{
"outcome" => "success",
"result" => {
"ActiveCount" => 1,
"AvailableCount" => 20,
"AverageBlockingTime" => 0L,
"AverageCreationTime" => 122L,
"AverageGetTime" => 128L,
"AveragePoolTime" => 0L,
"AverageUsageTime" => 0L,
"BlockingFailureCount" => 0,
"CreatedCount" => 1,
"DestroyedCount" => 0,
"IdleCount" => 1,
...
}
以下管理 CLI 命令检索 ExampleDS 数据源的 JDBC 统计数据：
/subsystem=datasources/data-source=ExampleDS/statistics=jdbc:read-resource(include-runtime=true)
{
"outcome" => "success",
"result" => {
"PreparedStatementCacheAccessCount" => 0L,
"PreparedStatementCacheAddCount" => 0L,
"PreparedStatementCacheCurrentSize" => 0,
"PreparedStatementCacheDeleteCount" => 0L,
"PreparedStatementCacheHitCount" => 0L,
"PreparedStatementCacheMissCount" => 0L,
"statistics-enabled" => true
}
}注意
由于统计信息是运行时信息，因此务必指定 include-runtime=true 参数。
使用管理控制台查看数据源统计信息
若要从管理控制台查看数据源统计信息，可从 Runtime 选项卡中导航到 Datasources 子系统，选择数据源，再单击 View。
