Metric Description
Containers Allocated Number of YARN containers currently allocated for the NodeManager instance on this node
CPU Node CPU use
HDFS I/O Number of bytes read and written for Hadoop
IP Address IP address of the node
Memory Percentage of memory use on the node
Name Name of the node
Network In Rate of network traffic into the node in bytes per second
Network Out Rate of network traffic out of the node in bytes per second
NM Memory Allocated Percent of available memory allocated by the NodeManager instance on this node
Rack ID User-defined name that specifies the physical location of the node
Type Class of node, such as Master or Data:
  • Data nodes are those running the HDFS datanode service or the YARN NodeManager service
  • Master nodes are those running the HDFS namenode service or the YARN ResourceManager service
  • Nodes that are not running any HDFS or YARN services are classified as type other
Unhealthy Services Count of services for the node that are in an unhealthy state
