Constructor Detail

JdbcMXBeanImpl

public JdbcMXBeanImpl(Manager manager)

MXBean constructor with prefix initialization to default (org.javasimon.jdbc).

Parameters:

manager - instance of Manager, typically SimonManager.manager().

JdbcMXBeanImpl

public JdbcMXBeanImpl(Manager manager,
              String prefix)

MXBean constructor with custom prefix initialization.

Parameters:

manager - instance of Manager, typically SimonManager.manager().

prefix - custom prefix

Method Detail

getPrefix

public String getPrefix()

Description copied from interface: JdbcMXBean

Returns actual prefix associated with mxbean.

Specified by:

getPrefix in interface JdbcMXBean

Returns:

actual prefix

setPrefix

public void setPrefix(String value)

Description copied from interface: JdbcMXBean

Sets custom prefix of JDBC Simon hierarchy, see more JdbcMXBean.

Specified by:

setPrefix in interface JdbcMXBean

Parameters:

value - new prefix

enableMonitoring

public void enableMonitoring()

Description copied from interface: JdbcMXBean

Enables monitoring (gathering statistics) by associated JDBC Simon hierarchy, see (org.javasimon.jdbc). Works if SimonManager is enabled, look SimonManager.isEnabled().

Specified by:

enableMonitoring in interface JdbcMXBean

disableMonitoring

public void disableMonitoring()

Description copied from interface: JdbcMXBean

Disables monitoring (gathering statistics) by associated JDBC Simon hierarchy, see (org.javasimon.jdbc). If SimonManager is already disabled has no effect, look SimonManager.disable().

Specified by:

disableMonitoring in interface JdbcMXBean

isMonitoringEnabled

public boolean isMonitoringEnabled()

Description copied from interface: JdbcMXBean

Returns state of monitoring JDBC driver.

Specified by:

isMonitoringEnabled in interface JdbcMXBean

Returns:

true if associated prefix is enabled; otherwise false

connectionsStat

public JdbcObjectInfo connectionsStat()

Description copied from interface: JdbcMXBean

Retrieves summary data about JDBC connection objects.

Specified by:

connectionsStat in interface JdbcMXBean

Returns:

value object JdbcObjectInfo

statementsStat

public JdbcObjectInfo statementsStat()

Description copied from interface: JdbcMXBean

Retrieves summary data about JDBC statement objects.

Specified by:

statementsStat in interface JdbcMXBean

Returns:

value object JdbcObjectInfo

resultsetsStat

public JdbcObjectInfo resultsetsStat()

Description copied from interface: JdbcMXBean

Retrieves summary data about JDBC result set objects.

Specified by:

resultsetsStat in interface JdbcMXBean

Returns:

value object JdbcObjectInfo

getSqlCommands

public String[] getSqlCommands()

Description copied from interface: JdbcMXBean

Returns SQL command types (select, insert, delete, etc). If client application uses DDL commands like create, alter and other, those are included too. Special case are batch-es, they are referenced as batch.

Specified by:

getSqlCommands in interface JdbcMXBean

Returns:

list of string (references to used SQL command types in monitored (simoned) application)

See Also:

JdbcMXBean.getSqlCommandStat(String), JdbcMXBean.getSqls(String)

getSqlCommandStat

public StopwatchSample getSqlCommandStat(String cmdId)

Description copied from interface: JdbcMXBean

Retrieves summary data about all executed SQL commands of eneterd type (for instance summary data of all executed selects).

Specified by:

getSqlCommandStat in interface JdbcMXBean

Parameters:

cmdId - SQL command type

Returns:

populated object StopwatchSample, or null if entered sql command type has no associated javasimon (it means, no sql of this type was executed yet, for instance no update was executed yet)

See Also:

JdbcMXBean.connectionsStat()

getSqls

public String[] getSqls(String cmdId)

Description copied from interface: JdbcMXBean

Returns hashs of different SQL commands of one type (select, insert, delete, etc). Each hash represent one sql command with (and its many executions).

Specified by:

getSqls in interface JdbcMXBean

Parameters:

cmdId - cmd SQL command type (select, insert, delete, etc)

Returns:

list of string (hash references to used SQL command in monitored (simoned) application)

See Also:

JdbcMXBean.getSqlCommands(), JdbcMXBean.getSqlStat(String)

getSqlStat

public StopwatchSample getSqlStat(String sqlId)

Description copied from interface: JdbcMXBean

Retrieves summary data about all same executed SQLs (for instance summary data of all executed select * from foo where bar => 0).

Specified by:

getSqlStat in interface JdbcMXBean

Parameters:

sqlId - hash code of sql command

Returns:

populated object StopwatchSample, or null if entered sql has no associated javasimon (it means, no sql like this was executed yet, for instance no update was executed yet)

JdbcMXBean.getSqls(String)
