This quick guide explains the difference between Hardware Health for Server & Application Monitor (SAM) and Network Performance Monitor (NPM).

 

Network Performance Monitor

-

• SAM Hardware Polling: 
  • SAM can monitor hardware (servers) from VMware hosts, HP ProLiant, Dell PowerEdge, and the IBM X-Series. 
  • Hardware monitoring is achieved by polling via SNMP, WMI, or VMware API, depending upon the node
     
• NPM Hardware Polling: 

  • NPM polls hardware health only for network devices, such as routers and switches using SNMP.
