红帽全球峰会13.10. 数据源统计
您可以查看定义的数据源的核心 池和 JDBC 运行时统计信息。如需了解所有可用 统计数据的详细列表，请参阅 Datasource 统计。
启用数据源统计
默认情况下，不启用 数据源统计信息。以下管理 CLI 命令启用 ExampleDS 数据源的统计信息集合。
注意
在受管域中，在这些命令之前使用 /profile=PROFILE_NAME。
/subsystem=datasources/data-source=ExampleDS/statistics=pool:write-attribute(name=statistics-enabled,value=true)/subsystem=datasources/data-source=ExampleDS/statistics=jdbc:write-attribute(name=statistics-enabled,value=true)查看数据源统计
所有数据源统计信息可以从管理 CLI 检索。这些统计数据的子集可以从管理控制台的 Runtime 选项卡查看。
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，在这些命令前面带有 /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 统计信息。
/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
由于统计数据是运行时信息，因此请务必指定 include-runtime=true 参数。
