Glances vs smartmontools

Glances is a free, open-source, cross-platform tool for monitoring real-time system statistics and running processes. Its listed coverage includes CPU, memory, load, processes, network, disk I/O, sensors, filesystems, containers, alerts, and uptime. Client/server mode enables remote monitoring through a terminal, web interface, or API, while its built-in web UI lets users view a system from a browser-equipped device. Statistics can be exported to CSV or JSON files, databases such as InfluxDB and Prometheus, brokers such as RabbitMQ and Kafka, or a REST endpoint. The project documents Docker and Podman support and describes Docker and LXC container monitoring in its README. Installation options include pip, pipx, Homebrew, Linux and FreeBSD packages, and Docker images. Glances 4 requires Python 3.10 or higher. Its default installation does not include web interface dependencies; separate extras cover features such as web, GPU, containers, exports, and MCP. Version 4.5.1 and higher can provide an MCP server for AI assistants. The project uses the LGPL version 3 license.

smartmontools is a free package containing smartctl and smartd for controlling and monitoring storage devices through SMART. It supports ATA/SATA, SCSI/SAS, and NVMe disks, as well as SCSI/SAS tape devices. smartctl can report SMART health status, show capabilities such as error logging and offline surface scanning, display vendor-specific attributes, start device self-tests, and read their logs. A failing health status can mean a device has failed or predicts failure within 24 hours. smartd periodically monitors SMART status, error and self-test logs, and attribute changes; it can schedule tests and report errors and attribute changes to syslog. It also supports warning emails and executable commands. The project says it should run on modern Linux, BSD variants, macOS, Solaris, Windows, Cygwin, OS/2, eComStation, and QNX systems, and can run from various Live CDs and DVDs. The package uses the GNU GPL Version 2 license and was originally derived from the Linux smartsuite package. Its capabilities focus on SMART health reporting, testing, and ongoing monitoring.
