[jboss-jira] [JBoss JIRA] (WFCORE-481) Logging async-handler improvement - report number dropped logs

Logging async-handler improvement - report number dropped logs -------------------------------------------------------------- Key: WFCORE-481 URL: https://issues.jboss.org/browse/WFCORE-481 Project: WildFly Core Issue Type: Enhancement Components: Logging Reporter: Todd Sandor Assignee: James Perkins The functional requirement is to know when logs are discarded and the number of logs discarded. When using a async-handler such as the one below, we do not know if/when logs are discarded, thousands could be dropped and we do not know it. <async-handler name="ASYNC"> <queue-length value="300000"/> <overflow-action value="discard"/> <subhandlers> <handler name="FILE"/> </subhandlers> </async-handler> Potential solution/suggestion: Add a new property, call it max-discard-logs, with a default value of 1 - uses existing behavior when = 1 (when queue full, drop any new log). When > 1 and queue is full, at least max-discard-logs logs are removed from the queue and display a log indicating the queue is full an N logs were dropped. <async-handler name="ASYNC"> <queue-length value="300000"/> <overflow-action value="discard"/> <max-discard-logs value="1000"/> <subhandlers> <handler name="FILE"/> </subhandlers> </async-handler> Depending upon the type of queue being used in the implementation, this could be a very simple change. e.g https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/BlockingQu... int drainTo(Collection<? super E> c, int maxElements) Removes at most the given number of available elements from this queue and adds them to the given collection.
