* ENT-3057: Log hibernate warns and errors in different log
If a hibernate error occurs (deadlock, for example) that would cause a flow to be sent to the hospital, hibernate logs the warnings and errors before we do. This results in duplication in the logs, and pollutes the log. To solve this, we create a new log appender named diagnostic-{node-name}.log and log any org.hibernate messages of warn and above to that file. This way, messages are not lost, which means that the information can be retrieved if need be.
* Corrected indentation of comment (changed tab to space)
* Updated node-administration document to mention diagnostic logging change
* Fixed integration test. It was breaking because it was fetching the first log file in the folder, assuming there would be only one. This assumption is now invalid because the diagnostic log file that was introduced. Two tests were found that used similar logic to find a log file to examine, hence both were corrected to look for log files beginning with "node"
* Updated documentation as per review comments.
* Provide AsyncLoggingContextSelector that inhibits use of thread local storage
* Turn on async logging via log4j properties file
* Mention async logging in the documentation and also explain how to turn it off when required.
* Formatting
* Typo
* Add shutdown hook to flush loggers.
* code review rework
* Ring buffer size to 256kB
* Set maximal log file size to 100MB - should slow down the rolling of log files and give us a bit more history on the cluster.
The old limit of max 10GB of compressed log files still stands.
* Introduce new h2Settings config block which overrides h2Port
* H2 server listens on localhost by default
* Change is backward compatible and old h2Port option can still be used but that always listens on localhost now
* Update changelog and docs with H2 changes
* Jolokia agents are loaded dynamically if configured
* Renamed exportJmxTo (never used) to jmxMonitoringHttpPort and take it from config
* Updated documentation and tests
* JMX Jolokia instrumentation WIP (driverDSL, webserver, cordformation, hibernate statistics, access policy config file hardening)
* Cordformation changes to support jolokia agent instrumentation at JVM startup.
* Minor updates to reflect usage of Jolokia 1.3.7 (which uses slightly different .war naming)
* Use relative path reference in -javaagent to prevent problem with long path names with spaces.
* Fixed incorrect regex pattern and added assertion to test.
* Enable JMX monitoring.
* Reporting of Hibernate JMX statistics is configurable (by default, only switched on in devMode)
* Make Artemis JMX enablement configurable.
* Re-instate banning of java serialization.
* Improve JUnit.
* Fixes following rebase from master.
* Re-instated correct regex for picking up Jolokia agent jar.
* Fixed broken integration test.
* Updated documentation
* Updated following PR review feedback.
* Fixed compilation error caused by change in DriverDSL argument type.
* Fixed compilation error caused by change in DriverDSL argument type.
* Fail fast if jolokia-agent-jvm.jar is not located.
* Applied changes in cordformation following review feedback from CA.
