End-to-End Observability Stack Deployment
📊 Observability and Monitoring Platform Link to heading
This project focuses on the design and deployment of a production-ready observability platform providing centralized metrics, logs, dashboards, and alerting across multiple services and environments. The solution replaces fragmented and ad-hoc monitoring practices with a structured, versioned and fully automated stack based on open-source components.
🧩 Technology Stack Link to heading
| Capability | Tools / Components |
|---|---|
| Metrics Collection | Prometheus, Node Exporter, Blackbox Exporter |
| Log Aggregation | Loki, Promtail |
| Visualization & Dashboards | Grafana |
| Alert Routing | Alertmanager (email, ticketing integration) |
| Provisioning & Automation | Terraform, Ansible |
| CI/CD Pipeline | GitLab CI (validation, testing, staged deployments) |
🏗 Architecture Overview Link to heading
The platform gathers infrastructure metrics such as CPU, memory, disk and network usage, along with application metrics exposed via HTTP endpoints. Service availability is continuously verified through Blackbox probes over HTTP/HTTPS and other supported protocols. Promtail forwards application and system logs to Loki, which together with Prometheus forms the data layer. Grafana connects to both engines for dashboards and troubleshooting, while Alertmanager ensures a structured and traceable incident response workflow.
⚙️ Automation and CI/CD Link to heading
The entire stack is defined as code. Terraform provisions compute instances, storage layers, networking and DNS configuration. Ansible installs and configures Prometheus, Loki, Grafana, Alertmanager and exporters consistently across test, staging and production environments. GitLab CI enforces formatting and security validation for Terraform and Ansible, validates Prometheus alert rules prior to deployment, and orchestrates controlled rollouts through multiple stages.
📈 Dashboards and Alerts Link to heading
Grafana provides dashboards showing infrastructure capacity, latency and error rate indicators, and log ingestion health. Operational and business stakeholders gain a complete view of service health and performance. Alertmanager routes incidents to email and ticketing systems, supporting clear traceability. Prometheus alert rules detect resource saturation, service unavailability and certificate expirations for proactive operations.
🚀 Outcomes Link to heading
The observability platform significantly reduces the time required to detect and diagnose incidents thanks to centralized access to metrics and logs. Automation and GitOps practices improve deployment reliability and repeatability. The organization gains enhanced visibility into infrastructure and application behavior, enabling better capacity planning and increased overall resilience.
