The racadm cli command with getsensorinfo subcommand fetches real-time live hardware sensor data such as temperature, voltage, and power, memory, processor status and other hardware information from a Dell server's iDRAC system. This is very useful to system administrators for monitoring server health remotely via CLI. It helps prevent hardware failures and optimize thermal management without needing to go to server physically or need physical access.
In the data provided, key hardware components such as PSUs / Power Supplies, CPUs / Processors, DIMMs / Memory / RAMs, fans, and system voltages are continuously checked and monitored. It helps IT teams proactively detect failing components, overheating CPUs, voltage irregularities, memory presence/absence, and even chassis intrusions. This command is helpful and ideal for automating health checks, integrating into monitoring tools, and improving data center operational reliability - all without depending on Web GUI-based tools or requiring physical access to servers.
Here is the command.
racadm -r <servername_ip> -u <username> -p <password> getsensorinfo --nocertwarn
