title: Apache Ignite 2.8.0: Node Metrics System View doesn't exist
body: <p>According to <a href="https://apacheignite.readme.io/docs/system-views" rel="nofollow noreferrer">documentation</a> ignite should expose the Node Metrics System View. However there is no such view in the code (<code>org.apache.ignite.spi.systemview.view</code> package). Is it a peace of not-implemented-yet feature or is it a bug in the documentation? </p>
