System administrator must, server monitoring lightweight tool
Server monitoring tools are critical to IT infrastructure performance, visualization, and system stability. The right tools can help system administrators face challenges such as server failures, application slowdowns, outages, memory leaks, and configuration dependencies.
Nagios, Zabbix, and other tools are used to monitor the entire infrastructure. With them, system administrators can monitor almost anything, such as server performance, network performance and protocols, operating systems, applications, and so on. But if your enterprise infrastructure is less complex, or you just need to monitor the performance of your server instead of using powerful end-to-end tools, you can use lightweight tools to monitor server health.
Ward
Ward provides the main information related to 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, processors, disks and partitions, CPU usage, and more.
To run Ward, you can create a JAR file and run it, or download the latest version of the JAR file and run it. You can also start Ward in a Docker container.
Netdata
Netdata is free, open source software for real-time monitoring of systems and applications. It runs on Linux, FreeBSD, macOS, Docker containers, and IoT devices. Users can install Netdata agents on systems, applications, or containers, which provide all performance and health information in real time.
Netdata can be easily integrated with other tools such as Prometheus, AWS Kinesis, Graphite, MongoDB, etc. Netdata is easy to install, monitors 1000 indicators on each node, and stores historical data per second.
Prometheus+Grafana
Prometheus is an open source tool for monitoring system metrics, and Grafana is an open source visualization platform. The integrated Prometheus and Grafana setup is a powerful environment for efficient server monitoring.
The Prometheus server collects all data periodically, Prometheus becomes the data source for Grafana, and Grafana visualizes all metrics on the dashboard. You can even select the metrics to be visualized by the query in Grafana.
Glances
Glances is a cross-platform monitoring tool written in Python. It only supports Python 2.7 or python3.4 and above, and it uses the Python library (psutil) to collect all system information.
Linux Dash
Linux Dash is a Web dashboard for Linux systems. The Linux Dash UI is built based on Angular and supports multiple languages on the server side. The System status TAB displays information about RAM usage, CPU load average, CPU usage, CPU and RAM processes, CPU temperature, and Docker processes. Linux Dash supports WebSocket to provide real-time system data visualization.
Conky
Conky runs on many different platforms, such as Windows, Linux, Mac OS, and most BSDS. It uses simple text or bus progress bars, as well as graphical Windows with different fonts and colors to display information. Advantage lies in the simple user interface, more than 300 built-in objects to display system status.
