In the document, Network Errors means Rate of network errors on JVM. But I am a little bit confused at JVM. Is JVM the container? If so, does this value represent the rate of drop package while connecting containers on the datanodes? https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-operations/content/grafana_hdfs_datanodes.html
