End-to-end Grafana observability

A complete Grafana stack — Alloy and Vector for collection, Mimir, Loki, and Tempo for storage — deployed across multiple clusters on ENGIE's DevOps platform.

production EKS clusters covered

Context

ENGIE Digital & IT's DevOps platform runs on 6 production EKS clusters and 200+ VMs, serving 600+ organizations. Metrics, logs, and traces are produced there continuously, at scale.

Challenge

Unify three signals — metrics, logs, traces — across several clusters, in a coherent, operable stack, without piling up agents or creating one silo per team.

Solution

Unified collection: Grafana Alloy and Vector deployed across all clusters.
A dedicated backend per signal: metrics with Prometheus and Mimir, logs with Loki, traces with Tempo.
Grafana dashboards and alerting, wired to the internal alert centralization tool (Python).
Multi-cluster deployment and operations on the production environments.
