Grafana and Prometheus Stack for Infrastructure Monitoring
Build production-grade monitoring and alerting with Prometheus, Grafana, and exporters.
About This Assessment
Observability and monitoring skills are critical for SRE and DevOps roles in 2026. This assessment tests practical implementation of the Prometheus/Grafana monitoring stack including metric collection with exporters, PromQL query writing, dashboard creation, and alert configuration. Candidates instrument real systems and create actionable monitoring for infrastructure and applications.
What Candidates Will Do
Deploy Prometheus and configure it to scrape metrics from Node Exporter and application exporters
Write PromQL queries to calculate SLI metrics like error rates, request latency percentiles, and resource utilization
Create Grafana dashboards with panels for key infrastructure and application metrics, including alerting annotations
Configure Prometheus alerting rules for critical conditions and validate alert firing via Alertmanager
Instrument a sample application with custom metrics and expose them for Prometheus scraping
Automated Grading
Verify Prometheus is scraping all configured targets successfully, confirm PromQL queries return accurate metric calculations, check Grafana dashboards render expected visualizations with proper units and thresholds, validate alert rules are configured and fire when conditions are met, ensure custom application metrics are exposed and collected by Prometheus
Environment
Ubuntu 22.04 with Prometheus, Grafana, Node Exporter, and sample applications (Python/Go with client libraries) pre-installed or ready to deploy. Include Alertmanager for alert routing.
