Monitoring and alerts (Grafana / Prometheus / Loki)

Without monitoring you learn about outages from customers. You get a complete observability stack: server metrics (Prometheus), application logs (Loki) and visualization with alerts (Grafana). This helps you spot issues sooner and reduce their business impact.

The problem

Most companies learn about server or application problems only from customers – when the store is down, the page won't load or orders aren't going through. Common situations: no monitoring (nobody knows the server is at 95% RAM usage), logs not collected or overwritten (after a failure you can't determine the cause), cron jobs silently stop working, SSL certificates expire and block traffic, disk fills up and the server stops. Without monitoring every incident is a surprise, and diagnostics take hours instead of minutes.

Scope of work

Installation and configuration of Prometheus (server and application metrics) with appropriate exporters
Deployment of Loki + Promtail for centralized collection and searching of application and server logs
Grafana configuration with dashboards: resource usage, uptime, response time, business metrics
Alert configuration: email, Slack, Telegram or webhook for critical events
Specific monitoring: cron jobs (heartbeat), SSL certificates, service availability, HTTP statuses
Documentation: what is monitored, alert thresholds, how to respond to specific alerts

What you get

Running Grafana + Prometheus + Loki stack configured for your environment
Dashboards with key server, application and business process metrics
Configured alerts with thresholds tailored to your traffic and resources
Centralized log repository with search and filtering capabilities
Monitoring documentation with alert descriptions and incident response procedures

Backup and restore

Monitoring and backups are the two pillars of security. An alert about a problem + confidence that data can be restored = peace of mind.

DevOps and Linux server administration

Monitoring is part of comprehensive server administration — combined with hardening, CI/CD and backups for full coverage.

Frequently Asked Questions

Why Grafana/Prometheus/Loki and not other tools?

This stack is open-source, battle-tested in production by thousands of companies, well-documented and easily extensible. Prometheus collects metrics, Loki aggregates logs, and Grafana visualizes everything in one place with alerts. It is an industry standard that avoids vendor lock-in.

What alerts do you configure?

Standard alerts include: high CPU/RAM/disk usage, service unavailability, HTTP 5xx errors, slow responses, failed cron jobs, expiring SSL certificates, failed backups. Thresholds are tailored to your traffic and resources — no false alarms.

Can I use the Grafana dashboards myself?

Yes, Grafana has an intuitive interface. After deployment you get a walkthrough on reading dashboards, filtering logs and responding to alerts — plus documentation with metric descriptions and procedures. Access is via browser from any device.

Does monitoring put load on the server?

Minimally. Prometheus and exporters use very few resources (typically below 1% CPU and a few dozen MB of RAM). For large environments the monitoring stack can run on a separate server, which is an added safeguard – monitoring works even when the main server goes down.
