This article will explain in detail the lightweight server monitoring tools that system administrators must have. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Server monitoring tools are critical to IT infrastructure performance, visualization, and system stability. The right tools can help system administrators face the challenges of server failures, slow applications, downtime, memory leaks, and configuration dependencies.

Nagios, Zabbix and other tools are used to monitor the entire infrastructure monitoring tools. Using them, system administrators can monitor almost everything, such as server performance, network performance, and protocols, operating systems, applications, and so on. But if the enterprise infrastructure is less complex, or if you just need to monitor server performance instead of using powerful end-to-end tools, you can use lightweight tools to monitor server health.

Ward

Ward provides the main information about the server. It is compatible with all popular operating systems. Ward uses OSHI, a free Java library for retrieving operating system and hardware information. It shares operating system version, memory, processor, disk and partition, CPU usage and other information.

To run Ward, you can create the jar file and run it, or download the latest version of the jar file and run it. You can also start Ward in the docker container.

Netdata

Netdata is free and open source software for real-time monitoring of systems and applications. It can be run on Linux,FreeBSD,macOS,docker containers and IoT devices. Users can install the Netdata agent on a system, application, or container, which will provide all performance and health information in real time.

Netdata can be easily integrated with other tools, such as Prometheus,AWS Kinesis,Graphite,MongoDB. Netdata is easy to install and can monitor 1000 indicators per node and store historical data per second.

Prometheus+Grafana

Prometheus is an open source tool for monitoring system metrics, while Grafana is an open source visualization platform. Integrated Prometheus and Grafana settings are a powerful environment for efficient monitoring of servers.

The Prometheus server collects all the data periodically, Prometheus becomes the data source for Grafana, and Grafana visualizes all metrics on the dashboard. You can even select metrics in Grafana for the query to visualize.

Glances

Glances is a cross-platform monitoring tool written in Python. It only supports python2.7 or above python3.4, and it uses the python library (psutil) to collect all system information.

Linux Dash

Linux Dash is the Web dashboard of the Linux system. Linux Dash's UI is built on Angular and is server-side supported in multiple languages. The system status tab displays information about RAM usage, CPU average load, CPU utilization, CPU and RAM processes, CPU temperature, and Docker processes. Linux Dash supports WebSocket to provide real-time system data visualization.

Conky

Conky can run on many different platforms, such as Windows,Linux,Mac OS and most BSD. It uses simple text or bus progress bars, as well as graphical windows with different fonts and colors to display information. The advantage is that the user interface is simple and there are more than 300 built-in objects to display the system status.
