What monitoring systems or tools have you used in your work and how did you configure them?

In my work, I used several monitoring systems, including Prometheus, Zabbix, and Grafana for data visualization.

Prometheus collects metrics from applications and infrastructure via exporters. It is configured through the prometheus.yml file, where targets for data collection, alert rules, and storage parameters are specified.

Example configuration of Prometheus:

scrape_configs:
  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']

Grafana is used to build dashboards based on data from Prometheus or other sources. Configuration is done through the web interface, where panels with the required metrics are created.

Zabbix is a more comprehensive solution with agents that collect metrics and events. Configuration includes setting up hosts, triggers, and actions through the web interface.

Overall, setting up monitoring involves:

• Defining key metrics and events
• Configuring data collection (agents, exporters)
• Creating alerts and notifications
• Visualizing data for easy analysis

This approach allows timely detection of problems and response to them.
