use single static initialization of available metrics monitor registries * This changes the original implementation to work in a similar way to how slf4j selects and loads an implementation. * Uses a single static instance so intialization is done only once. * Doesn't throw IllegalStateException if multiple implementations are found on the classpath. It instead selects and uses the first implementation returned by iterator() * Class left as an iterable to keep the API the same add yammer metrics to examples to allow them to publish metrics publish the number of threads used in an EventLoopGroup see issue #718 * seems like the better place to put this because it sets the default thread count if the MultithreadEventLoopGroup uses super(0,...) * It also happens to be the common parent class amongst all the MultiThreadedEventLoopGroup implementations * Count is reported for io.netty.channel.{*,.local,.socket.aio,.socket.nio} fix cosmetic issues pointed out in pull request and updated notice.txt see https://github.com/netty/netty/pull/780 count # of channels registered in single threaded event loop measure how many times Selector.select return before SELECT_TIME |
