What monitoring system components are you familiar with or have used?

Monitoring systems typically use the following components:

• Metrics collection: agents or exporters (e.g., Prometheus Node Exporter, Telegraf) that gather data about system, application, and resource status.
• Data storage: time series databases (TSDB) — Prometheus, InfluxDB.
• Visualization: monitoring dashboards (Grafana) for displaying metrics in a user-friendly way.
• Alerting: notification systems (Alertmanager, Zabbix) that send alerts when thresholds are reached.
• Logging: collection and analysis of logs (ELK stack — Elasticsearch, Logstash, Kibana).

I used Prometheus for metrics collection, Grafana for visualization, and Alertmanager for setting up alerts.
