24 alternatives to FSM – an advanced system monitor for Linux

Version v0.5.0 is now available, it is already working stably, although in terms of functionality and consumption of PC resources, I still have a lot to strive for. FSM shows information about processors, RAM, mounted file systems, some information from DMI, etc.
