Know before the customer does
The site went down, and you found out an hour later from users — that's not normal. A monitoring system tracks the state of servers, applications and databases in real time and sends an alert before the problem becomes an incident.
What we monitor
Not just "is the server alive or not." We see degradation in its early stages: rising API response times, slow DB queries, the disk filling up with logs - hours before a crash.
- CPU, RAM, disk, network for each server and service
- Uptime monitoring for HTTP, TCP and DNS with checks every minute
- Application metrics - response time, errors, queues
- Database monitoring - slow queries, connections, table sizes
- Centralized log collection via Loki from all services
- Alerts to Telegram, Slack, Email or MAX with scheduled escalation
Stack
Prometheus collects metrics, Grafana builds dashboards, Loki aggregates logs, Alertmanager manages notifications. Historical data is kept for months - degradation trends become visible long before the server starts to choke.
