Method Detail

begin

public void begin(Metrics.ConnectionEvent event)

Description copied from class: Metrics

All begin and end calls are noop in this class because this class is instantiated when metrics capturing is disabled. The subclass of this is instantiated when metrics capturing is enabled. This is to avoid 'is capturing metrics enabled' checks in begin and end methods.

Overrides:

begin in class Metrics

begin

public void begin(Metrics.ConnectionEvent event,
                  int retryIdentifier)

Driver retries some events like 'Generate PK', 'SSL Renegotiation Receive', 'SSL Renegotiation RunTasks'. The begin and end calls put those retried events in the consolidated metric map with key as event name suffixed by retry identifier. E.g. 'Generate PK 1', 'SSL Renegotiation Receive 1'. For the cases where there is no retry, there won't be any suffix .

Overrides:

begin in class Metrics

Parameters:

event -

retryIdentifier -

end

public void end(Metrics.ConnectionEvent event)

Overrides:

end in class Metrics

end

public void end(Metrics.ConnectionEvent event,
                int retryIdentifier)

Driver retries some events like 'Generate PK', 'SSL Renegotiation Receive', 'SSL Renegotiation RunTasks'. The begin and end calls put those retried events in the consolidated metric map with key as event name suffixed by retry identifier. E.g. 'Generate PK 1', 'SSL Renegotiation Receive 1'. For the cases where there is no retry, there won't be any suffix .

Overrides:

end in class Metrics

Parameters:

event -

retryIdentifier -

close

public void close()

The map events and metrics is added to the collection.

Overrides:

close in class Metrics

Parameters:
