It helps an administrator see: 1. **Server load.** How many connections, how much memory and CPU are being used. 2. **Query performance.** Which queries are "dragging down" the system. 3. **Errors and failures.** Failed connection attempts, transaction errors, overflowing logs. 4. **Disk space usage.** To free up or expand storage in time. 5. **The state of replication and backups.** To confirm the copies are actually working correctly. Example tools: **pgAdmin, Zabbix, Prometheus, MySQL Workbench, Grafana**. **Summary:** monitoring exists to keep the database **running stably, quickly, and without surprises**, and to let the administrator learn about a problem **before users notice it**.For the reviewerNote to the moderator (optional)Visible only to the moderator.
