[FLINK-5446] [docs] Rework system-metrics section
----
> GraphiteReporter class not found at startup of jobmanager
> ---------------------------------------------------------
>
> Key: FLINK-4396
> URL: https://issues.apache.org/jira/browse/FLINK-4396
> Project: Flink
> Issue Type: Improvement
> Components: Build System, Metrics
> Affects Versions: 1.1.1
> Environment: Windows and Unix
> Reporter: RWenden
> Assignee: Chesnay Schepler
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> For Flink 1.1.1 we configured Graphite metrics settings on the
> flink-conf.yaml (for job manager (and taskmanager)).
> We see the following error in the log:
> 2016-08-15 14:20:34,167 ERROR org.apache.flink.runtime.metrics.MetricRegistry
> - Could not instantiate metrics reportermy_reporter. Metrics
> might not be exposed/reported.
> java.lang.ClassNotFoundException:

> org.apache.flink.runtime.metrics.MetricRegistry.<init>(MetricRegistry.java:119)
> We found out that this class is not packaged inside flink-dist_2.11-1.1.1.jar.
> Long story short: we had to install/provide the following jars into the lib
> folder to make Graphite metrics to work:
> flink-metrics-graphite-1.1.1.jar
> flink-metrics-dropwizard-1.1.1.jar
> metrics-graphite-3.1.0.jar (from dropwizard)
> We think these libraries (and the ones for Ganglia,StatsD,...) should be
> included in flink-dist_2.11-1.1.1.jar, for these are needed at manager
> startup time.
