I've been using NPM to monitor switches and routers for quite a while with great success, but now would like to try and monitor my VMware hosts which are Dell R710 servers. I'm not clear on what I need to do to make this happen. Do I need to enable SNMP in ESXi? Or does Orion somehow talk to the IDRAC controller within the server? I was able to add the ESXi host as an ICMP managed node and tell it to poll for VMware and that worked to show my VMs, but of course I don't see anything about the host *hardware* like CPU, fans, drives, memory, power supply, etc of the host by doing that.
Can someone point me in the right direction for monitoring server hardware?
