How do you organize a monitoring system for an infrastructure of two hundred servers?

For monitoring an infrastructure of two hundred servers, centralized monitoring systems are usually used, which collect metrics, logs, and service status from each server.

Main steps:

1. Choosing a monitoring system — popular options: Prometheus + Grafana, Zabbix, Nagios, Datadog.
2. Installing agents on servers — for example, node_exporter for Prometheus or zabbix-agent.
3. Collecting metrics and logs — CPU, memory, disk, network, service status.
4. Setting up alerts — notifications when thresholds are exceeded.
5. Data visualization — dashboards for quick analysis of the status.

Example with Prometheus:

• Each server runs node_exporter.
• Prometheus is configured to collect metrics from these agents.
• Grafana connects to Prometheus and builds dashboards.

This approach is scalable, allows quick problem detection, and enables prompt response.
