Today I’ll talk about a very important type of monitoring that is rarely discussed (perhaps because not so many people are privileged to work with hardware that supports this technology: IPMI).
The Intelligent Platform Management Interface (IPMI) is a standard used to manage a computer system and monitor its operation. Its development was led by Intel and is today supported by more than 200 hardware manufacturers.
Its operation is independent of an operating system, which allows administrators to remotely manage the hardware resources even before any OS starts. For example, we can monitor through IPMI system temperatures, voltages, fans (FAN), power supplies, chassis intrusion, etc..
For the ones that wants to go deeper in IPMI specifics, I suggest reading the website of Intel . I think the most interested in this are the Data Center Managers and System Administrators of sites that must be highly available. An IPMI interface collects information using sensors that are responsible for providing this information in real-time.
