  • 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.
