Method Detail

getInstance

public static SqlStatistic getInstance()

Gets the single instance of SqlStatistic.

Returns:

single instance of SqlStatistic

reset

public void reset()

To start a new statistic call this method. In contradiction to ProfileStatistic.reset() old ProfileMonitors will be not kept.

Specified by:

reset in interface ProfileStatisticMBean

Overrides:

reset in class ProfileStatistic

start

public static ProfileMonitor start(String sql)

Start.

Parameters:

sql - the sql

Returns:

the started profile monitor

stop

public static void stop(ProfileMonitor mon,
                        String command)

Stops the given 'mon' and logs the given command with the needed time if debug is enabled.

Parameters:

mon - the mon

command - the command

stop

public static void stop(ProfileMonitor mon,
                        String command,
                        Object returnValue)

Stops the given 'mon' and logs the given command with the needed time if debug is enabled.

Parameters:

mon - the mon

command - the command

returnValue - the return value

addAsShutdownHook

public static void addAsShutdownHook()

You can register the instance as shutdown hook. If the VM is terminated the profile values are logged and dumped to a CSV file in the tmp directory.
