Column Display

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

The following table lists all of the data points that you can display in columns on this page.

Name	Description
Server	The server on which the data source is deployed.
Active Connections Average Count	Average number of active connections in this instance of the data source. Active connections are connections in use by an application. MBean Attribute: `JDBCDataSourceRuntimeMBean.ActiveConnectionsAverageCount`
Active Connections Current Count	The number of connections currently in use by applications. MBean Attribute: `JDBCDataSourceRuntimeMBean.ActiveConnectionsCurrentCount`
Active Connections High Count	Highest number of active database connections in this instance of the data source since the data source was instantiated. Active connections are connections in use by an application. MBean Attribute: `JDBCDataSourceRuntimeMBean.ActiveConnectionsHighCount`
Connection Delay Time	The average time in milliseconds that it takes to create a physical connection to the database. The value is calculated as summary of all times to connect divided by the total number of connections. MBean Attribute: `JDBCDataSourceRuntimeMBean.ConnectionDelayTime`
Connections Total Count	The cumulative total number of database connections created in this data source since the data source was deployed. MBean Attribute: `JDBCDataSourceRuntimeMBean.ConnectionsTotalCount`
Current Capacity	The current count of JDBC connections in the connection pool in the data source. MBean Attribute: `JDBCDataSourceRuntimeMBean.CurrCapacity`
Curr Capacity High Count	Highest number of database connections available or in use (current capacity) in this instance of the data source since the data source was deployed. MBean Attribute: `JDBCDataSourceRuntimeMBean.CurrCapacityHighCount`
Enabled	Indicates whether the data source is enabled or disabled: `true` if the data source is enabled. `false` if the data source is disabled. MBean Attribute: `JDBCDataSourceRuntimeMBean.Enabled`
Failed Reserve Request Count	The cumulative, running count of requests for a connection from this data source that could not be fulfilled. MBean Attribute: `JDBCDataSourceRuntimeMBean.FailedReserveRequestCount`
Failures To Reconnect Count	The number of times that the data source attempted to refresh a database connection and failed. Failures may occur when the database is unavailable or when the network connection to the database is interrupted. MBean Attribute: `JDBCDataSourceRuntimeMBean.FailuresToReconnectCount`
Highest Num Available	Highest number of database connections that were available at any time in this instance of the data source since the data source was deployed. MBean Attribute: `JDBCDataSourceRuntimeMBean.HighestNumAvailable`
Leaked Connection Count	The number of leaked connections. A leaked connection is a connection that was reserved from the data source but was not returned to the data source by calling `close()`. MBean Attribute: `JDBCDataSourceRuntimeMBean.LeakedConnectionCount`
Num Available	The number of database connections currently available (not in use) in this data source. MBean Attribute: `JDBCDataSourceRuntimeMBean.NumAvailable`
Num Unavailable	The number of database connections that are currently unavailable (in use or being tested by the system) in this instance of the data source. MBean Attribute: `JDBCDataSourceRuntimeMBean.NumUnavailable`
PrepStmt Cache Access Count	The cumulative, running count of the number of times that the statement cache was accessed. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheAccessCount`
Prep Stmt Cache Add Count	The cumulative, running count of the number of statements added to the statement cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements added to the caches for all connections in the connection pool. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheAddCount`
Prep Stmt Cache Current Size	The number of prepared and callable statements currently cached in the statement cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements in the caches for all connections in the connection pool. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheCurrentSize`
Prep Stmt Cache Delete Count	The cumulative, running count of statements discarded from the cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements that were discarded from the caches for all connections in the connection pool. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheDeleteCount`
Prep Stmt Cache Hit Count	The cumulative, running count of the number of times that statements from the cache were used. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheHitCount`
Prep Stmt Cache Miss Count	The number of times that a statement request could not be satisfied with a statement from the cache. MBean Attribute: `JDBCDataSourceRuntimeMBean.PrepStmtCacheMissCount`
Reserve Request Count	The cumulative, running count of requests for a connection from this data source. MBean Attribute: `JDBCDataSourceRuntimeMBean.ReserveRequestCount`
State	The current state of the data source. Possible states are: `Running` - the data source is enabled (deployed and not SUSPENDED). This is the normal state of the data source. `Suspended` - the data source has been manually disabled. `Shutdown` - the data source is shutdown and all database connections have been closed. `Unhealthy` - all connections are unavailable (not because they are in use). This state occurs if the database server is unavailable when the data source is created (creation retry must be enabled) or if all connections have failed connection tests (on creation, on reserve, or periodic testing). `Unknown` - the data source state is unknown. MBean Attribute: `JDBCDataSourceRuntimeMBean.State`
JDBC Driver Version	The driver class name and version of the JDBC driver used to create database connections. The value returned the driver class named concatenated with 'major: XX, minor: YY' version information. MBean Attribute: `JDBCDataSourceRuntimeMBean.VersionJDBCDriver`
Wait Seconds High Count	The cumulative total number of database connections created in this data source since the data source was deployed. MBean Attribute: `JDBCDataSourceRuntimeMBean.ConnectionsTotalCount`
Waiting For Connection Current Count	The number of connection requests waiting for a database connection. MBean Attribute: `JDBCDataSourceRuntimeMBean.WaitingForConnectionCurrentCount`
Waiting For Connection Failure Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection and eventually failed to get a connection. Waiting connection requests can fail for a variety of reasons, including waiting for longer than the ConnectionReserveTimeoutSeconds. MBean Attribute: `JDBCDataSourceRuntimeMBean.WaitingForConnectionFailureTotal`
Waiting For Connection High Count	Highest number of application requests concurrently waiting for a connection from this instance of the data source. MBean Attribute: `JDBCDataSourceRuntimeMBean.WaitingForConnectionHighCount`
Waiting For Connection Success Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection and eventually succeeded in getting a connection. MBean Attribute: `JDBCDataSourceRuntimeMBean.WaitingForConnectionSuccessTotal`
Waiting For Connection Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection, including those that eventually got a connection and those that did not get a connection. MBean Attribute: `JDBCDataSourceRuntimeMBean.WaitingForConnectionTotal`
