AppControl vs nmon

AppControl is a free historical Task Manager for Windows that records system activity and application behavior over time. It keeps approximately 72 hours of second-by-second history covering CPU, GPU, memory, disk, temperature, and app events. Executables are described in plain language with publisher, signature, and elevated-privilege information. Alerts can flag webcam, microphone, or location access, along with new or unsigned apps and silent updates. Users can disable an app, block a publisher, and create rules to stop software from returning. History is stored locally. An optional MCP server connects compatible AI clients after you enable it and approve data access; its nine tools are read-only and cannot change rules or configuration. A command-line tool shows live resource use and process events. AppControl supports modern Windows 10 and Windows 11, requires administrator privileges to install, and is not an antivirus replacement.

nmon is a free Linux tool for systems administration, tuning, and performance benchmarking. It collects system information and presents live readings in a terminal through a curses interface. Keyboard controls let operators turn individual data categories on or off. The display can include CPU, memory, network, disks, filesystems, NFS, top processes, and, in the Linux version, resources and processors. Captured readings can be written to a comma-separated file for later analysis or longer-term recording. nmonchart converts output into webpage graphs, while nmon Analyser loads files into Excel and creates graphs. njmon injectors can add JSON data to InfluxDB and Splunk, with real-time graphing through InfluxDB and Grafana. Binaries are listed for POWER, x86, x86_64, mainframe, and ARM Linux. Unsupported distributions require compiling with GCC and the ncurses development library. The Linux project is GPLv3; AIX nmon is integrated into topas and is not open source.
