See inside your systems before users feel the pain.
Monitoring tells you something is wrong. Observability helps you find out why through practical metrics, logs, traces, dashboards, and alerting.

Course idea
Monitoring answers known questions: is it up, is it slow? Observability lets you ask new questions from the data your system already emits.
The course connects collection, storage, visualization, alerting, and incident response so learners can understand system behavior before it becomes a user-impacting problem.
Learning path
App
→ Exposes signals
→ Prometheus
→ Grafana
→ On-call
Choose self-hosted Prometheus and Grafana for open-source control, or learn Datadog for fast setup, one pane of glass, and a managed operating model.
Course modules
Build an observability stack your team can trust.
Grafana
Visualize and explore
- Dashboards across many data sources
- Prometheus, Loki logs, and Tempo traces
- Variables, annotations, and alert rules
- Share dashboards as code using JSON and provisioning
Datadog
All-in-one managed platform
- Agent metrics, logs, and traces from hosts and containers
- APM, RUM, synthetics, SLOs, and monitors
- 700+ integrations with no servers to run
- Understand the convenience versus cost-control trade-off
Self-hosted
Prometheus plus Grafana is open source and gives you full control, but your team runs and maintains it.
Managed
Datadog offers fast setup and one pane of glass, with usage-based pricing and less infrastructure to manage.
Practical habits
Four golden signals to watch
Latency - Traffic - Errors - Saturation. Alert on symptoms users feel, not on every CPU blip.
