Migrate to Open-Source Observability Stack

Job ID: 40268264

Budget: €1,500 – €3,000 EUR

Replace Datadog With OSS Stack
We spend about €1,400 each month on Datadog and want to eliminate that cost by running an open-source observability stack—Prometheus for metrics, Loki for logs, Alertmanager for notifications and Grafana for visualisation—inside our existing Kubernetes cluster.
Today Datadog covers three things for us: monitoring & alerting, log management and detailed performance metrics. I need the same coverage after the migration, and I need it in real time; anything slower is a non-starter. I also have several dashboards in Datadog that the team relies on every day. Those dashboards must be migrated into Grafana with the same look, data sources and alert thresholds.
Deliverables

Helm (or Kustomize) manifests that deploy Prometheus, Loki, Alertmanager and Grafana on our cluster, following best-practice security and resource limits.
Dashboards recreated or imported in Grafana so they match our current Datadog views one-for-one.
Alert rules configured to fire through our existing channels (Slack and email).
Log collection pipeline from Kubernetes pods into Loki with filters and retention policies set.
A hand-off document (or short video) that explains how to operate, upgrade and scale the stack.

Acceptance criteria
Metrics, logs and alerts visible in Grafana within two seconds of generation.
All existing Datadog dashboards reproduced accurately.
Zero critical Alertmanager silences or lost logs during switchover.

If you have proven experience replacing Datadog with Prometheus/Loki/Grafana in production Kubernetes environments this is the project for you.
