  1. Zabbix
    Zabbix is one of the popular tools for monitoring server performance. It provides a wide range of options for tracking various metrics, such as CPU load, memory usage, network traffic, and more. Zabbix also offers a flexible notification system for potential problems.

  2. Prometheus
    Prometheus is an open-source monitoring system that focuses on collecting time-series metrics. It has a powerful query language, PromQL, for data analysis and report generation. Prometheus also supports horizontal scaling to handle large amounts of data.

  3. Grafana
    Grafana is a visualization tool that allows you to create colorful dashboards based on data from various sources, including Zabbix, Prometheus, and other monitoring systems. Grafana allows you to quickly track changes in server performance, as well as configure problem notifications.

Installation and Configuration of Monitoring Programs

To install Zabbix, Prometheus, and Grafana on virtual servers, you can use ready-made packages for various operating systems. Then you need to configure the connection to the monitored servers, define the metrics of interest, and configure problem notifications.

Example of installing Prometheus on Ubuntu:



sudo apt-get update

sudo apt-get install prometheus

Monitoring Results

After installing and configuring the monitoring system, it is necessary to regularly monitor the performance data of virtual servers. Assessing CPU load, memory usage, network traffic, and other indicators will help identify potential problems and take measures to eliminate them.

Conclusion

Effective monitoring of virtual server performance is an important aspect of maintaining their stable operation. The right choice of monitoring tool, installation and configuration of programs, regular monitoring of results — all these are ways to ensure high server performance and prevent potential problems.
