Tell us about your experience with monitoring tools: Zabbix, Prometheus, Grafana.

In my practice, I have used Zabbix, Prometheus, and Grafana for monitoring and visualizing system status.

• Zabbix: used for monitoring servers and network equipment. I configured agents, created triggers for alerts, and used templates for standardizing monitoring. Good for monitoring infrastructure with a large number of hosts.

• Prometheus: used for collecting metrics from applications and services. I configured exporters and wrote alerting rules. Prometheus is convenient for monitoring microservices and dynamic environments thanks to its pull model and powerful query language PromQL.

• Grafana: used for building dashboards based on data from Prometheus and Zabbix. I created visualizations, combined metrics, and set up alerts.

Example: for a microservices application, I configured Prometheus to collect metrics on HTTP requests, errors, and response times, and in Grafana, I created a dashboard with key metrics and alerts for threshold breaches. For servers, I used Zabbix to monitor CPU load, memory, and disks.

This stack allows for quick problem detection and response.
