An Efficient Profiling Tool for Baseboard Management Controllers

The Baseboard Management Controller (BMC)1 is a specialized controller for monitoring servers remotely. By using the BMC, administrators of servers can quickly inspect hardware in case a server fails. A fast booting of the BMC is essential for inspecting hardware quickly. In this paper, we propose an efficient profiling tool to analyze the boot process of the BMC system. The proposed tool reduces boot time by supporting kernel version management, CPU and memory utilization analysis, and tracing of functions called during kernel-space boot. In addition, it implements the function proposed in Linux and shows that the analysis function of the proposed tool is effective in reducing the boot time.
