- Borrow SLF4J API which is the best of the best
- InternalLoggerFactory now automatically detects the logging framework
using static class loading. It tries SLF4J, Log4J, and then falls back
to java.util.logging.
- Remove OsgiLogger because it is very likely that OSGi container
already provides a bridge for existing logging frameworks
- Remove JBossLogger because the latest JBossLogger implementation seems
to implement SLF4J binding
- Upgrade SLF4J to 1.7.2
- Remove tests for the untestable logging frameworks
- Remove TestAny
First cut at implementing a generic abstraction layer for pluggable
metrics providers. This first cut is closely modeled after Yammer
Metrics. It remains to be seen if it is indeed flexibel enough to
support other providers.
Provide a default implementation of this new abstraction layer
based on Yammer Metrics.
Support pluggable Monitoring Providers using Java 6's ServiceLoader.
Use this new abstraction layer to provide stats on (a) number of
Timeouts executed per second and (b) distribution of absolute
deviation between scheduled and actual Timeout execution time in
HashedWheelTimer.
* Interface ValueDistributionMonitor, a monitor for histograms.
* Interface EventRateMonitor, a monitor for measuring the rate per time
unit of specific events.
* Interface ValueMonitor, a monitor for tracking an arbitrary datum's
current value
* Interface CounterMonitor, a monitor for incrementing/decrementing a
long value
* Interface MonitorRegistry, a registry for monitors that serves as the
interface between Netty and concrete metrics providers as e.g. Yammer
Metrics.
* Interface MonitorRegistryFactory, to be implemented by metrics
providers.
* Document how to use Netty's new monitoring support in javadocs for
package io.netty.monitor.
