Get server sensor detail over IPMI (iDRAC / iLO etc.)
Query and parse your Dell iDRAC sensor data, such as fan speeds / temp sensors into a Node-RED message.
Step 1: ensure that IPMI over LAN is enabled within iDRAC. Pull up the web interface to iDRAC and under iDRAC Settings > Network > IPMI Settings (top navigation bar) then check "Enable IPMI Over LAN"
Step 2: install ipmitools on your Node-RED server. e.g. on Ubuntu just run this: sudo apt install ipmitool
Step 3: import this flow, and change the value for IP address and password in the exec node
Sensor data is parsed into msg.data
