Detailed Description

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
