* The EventLogger is primarily used for logging NDB events
|
|
* in the Management Server. It inherits all logging functionality of Logger.
|
|
*
|
|
* HOW TO USE
|
|
*
|
|
* 1) Create an EventLogger
|
|
*
|
|
* EventLogger myEventLogger = new EventLogger();
|
|
*
|
|
* 2) Log NDB events and other log messages.
|
|
*
|
|
* myEventLogger->info("Changing log levels.");
|
|
*
|
|
* EventReport* report = (EventReport*)&theSignalData[0];
|
|
* myEventLogger->log(eventReport->getEventType(), theSignalData, aNodeId);
|
|
*
|
|
*
|
|
* The following NDB event categories and log levels are enabled as default:
|
|
*
|
|
* EVENT-CATEGORY LOG-LEVEL
|
|
*
|
|
* Startup 4
|
|
* Shutdown 1
|
|
* Statistic 2
|
|
* Checkpoint 5
|
|
* NodeRestart 8
|
|
* Connection 2
|
|
* Error 15
|
|
* Info 10
