Top 6 Server Monitoring Tools Every Sysadmin Should Know
Discover six essential server monitoring tools—including Conky, Glances, Linux Dash, Netdata, Prometheus + Grafana, and Ward—that help system administrators track performance, visualize metrics, and maintain reliable infrastructure across diverse platforms.
Server monitoring tools are indispensable for system administrators. Below are six recommended tools.
1. Conky runs on many platforms such as Windows, Linux, macOS, and most BSDs. It offers simple text, progress bars, and graphical windows with various fonts and colors, providing over 300 built‑in objects that make it a powerful utility for administrators.
2. Glances
Glances is a cross‑platform monitoring tool written in Python, requiring Python 2.7 or Python 3.4+. It uses Python libraries to collect system information.
3. Linux Dash
Linux Dash’s UI is built with Angular and serves as a web dashboard for Linux systems. It supports multiple languages and displays RAM usage, average CPU load, CPU utilization, and more. It can also provide real‑time data visualization via WebSocket.
4. Netdata
Netdata is open‑source software for real‑time monitoring of systems and applications. It runs on Linux, FreeBSD, macOS, Docker containers, and IoT devices, and integrates easily with tools like Prometheus, AWS Kinesis, Graphite, and MongoDB. It is free to use.
5. Prometheus + Grafana
Prometheus is an open‑source system‑metrics collector, while Grafana is an open‑source visualization platform. Together they form a powerful environment for efficient server monitoring: Prometheus gathers data, and Grafana visualizes it on dashboards with query capabilities.
6. Ward
Ward works with almost all popular operating systems and uses OSHI, a free Java library, to retrieve OS and hardware information. It can display OS version, CPU usage, disk partitions, processor details, memory usage, and more.
