Kubernetes Observability Platform
Built a Kubernetes observability platform for centralized cluster metrics, container logs, Grafana dashboards, and automated alerting using Prometheus and Loki.
// ARCHITECTURE_TOPOLOGY
Problem Statement & Context
Establish centralized visibility across Kubernetes nodes, workloads, and application services by collecting infrastructure metrics and container logs, presenting them through Grafana dashboards, and generating actionable alerts for operational issues.
Solution & Delivery Approach
Deployed the kube-prometheus-stack using Helm to provide Prometheus, Grafana, Alertmanager, kube-state-metrics, and node-exporter. Integrated Loki and Promtail for centralized container-log collection, configured Kubernetes monitoring resources and alert rules, and created Grafana dashboards for metrics and log exploration.
Engineering Challenges & Resolution
Excessive metric series and unnecessary log labels increased memory usage within the monitoring stack. Reduced ingestion overhead by refining scrape targets and intervals, removing unnecessary high-cardinality labels, tuning Promtail pipelines, and defining appropriate resource limits for monitoring components.
// Key_OUTCOMES
- ✓Established centralized visibility into Kubernetes node, workload, and application health.
- ✓Combined Prometheus metrics and Loki logs within Grafana for easier operational investigation.
- ✓Implemented repeatable Helm-based installation and configuration of the monitoring stack.
- ✓Validated alert generation and notification routing for selected Kubernetes failure conditions.
- ✓Improved practical understanding of Kubernetes-native metrics, log aggregation, dashboards, and alert management.
