μMon is an author’s personal take on host monitoring, designed to be minimalist and opinionated. It is based on technologies such as RRDtool, SNMP, lightweight shell scripting, and a small FastCGI server written in C++. The author migrated from a more complex monitoring setup to μMon in order to reduce complexity and create a durable, long-term solution. The stack used in μMon is lightweight, comprehensible, and has minimal dependencies. The author emphasizes the importance of simplicity and durability in personal computing. The author acknowledges that μMon may not suit everyone’s needs and is not meant to replace existing monitoring stacks.
