- org.opends.server.loggers.LogAggregator

```
public final class LogAggregator
extends Object
```
A simple log aggregator to prevent a burst of regularly repeated messages from flooding the logs.
The aggregation can be based on time or on count.
Messages known to be generated for an event occurring very frequently, for every protocol message or periodically, can be logged at first occurrence and then only at increasing intervals (if based on time), or only after a number of occurrences (if based on count).

  - log
```
public void log(Consumer<LocalizableMessage> logMethod,
                LocalizableMessage message)
```
    Log a message and start the aggregation for it.
    The message will be logged right away and if repeated, at fixed intervals. In case of burst (more than 20 times in a second), there will be a warning about it.
    
    Parameters:
    
    logMethod - how to log the message
    
    message - the message
  - countBasedLog
```
public void countBasedLog(LocalizedLogger logger,
                          LocalizableMessage message)
```
    Start the aggregation for a message that will be logged based on count and only after 2 occurrences.
    The message will be logged once as WARNING after 2 occurrences and once as ERROR after 5 occurrences. After that it will be logged at fixed intervals. In case of burst (more than 20 times in a second), there will be a warning about it.
    This behavior is suited for connections errors.
    
    Parameters:
    
    logger - logger to use for the message
    
    message - the message
  - purgeAndLogMessageBursts
```
public void purgeAndLogMessageBursts()
```
    Purge expired messages and log message bursts if any.
