Introduction 1.1 to enable local resources listeners: these listeners broadcast local resource changes as cluster events. Please note that this behavior is disabled by default as it can have side effects (especially when "isolated" from the cluster as it doesn’t send "outbound" cluster events to the other nodes. On the other hand, a node receives the cluster events on a consumer. Like for the producer, you can see and control

kinds of data. We have two kinds of collectors: ◦ Event Driven Collectors automatically react to events and send the event data to the Decanter appenders. ◦ Polled Collectors are periodically called x - Documentation - 1 Two kinds of collector are available: • Event Driven Collectors react to events and "broadcast" the data to the appenders. • Polled Collectors are periodically executed by the Collector is an event driven collector. It creates a socket, waiting for incoming event. The expected events are log4j LoggingEvent. The log4j LoggingEvent is transformed as a Map containing the log details

application. The "Service Wrapper" is able to detect crashes, freezes, out of memory and other exception events, then automatically react by restarting Apache Karaf with a minimum of delay. It guarantees the b 4.7.6. Advanced configuration Filters You can use filters on an appender. Filters allow log events to be evaluated to determine if or how they should be published. Log4j provides ready to use filters: filters: • The DenyAllFilter ( org.apache.log4j.varia.DenyAllFilter ) drops all logging events. You can add this filter to the end of a filter chain to switch from the default "accept all unless instructed
