The challenge
The existing monitoring had grown over the years. Different departments used different alerting rules and log structures – without a central overview. The costs for log ingestion rose continuously, while the quality of alerts decreased: too much noise, too little relevance. At the same time, a uniform strategy for security logs and their integration was missing. Changes to the monitoring configuration were made manually and were difficult to trace. The goal: A modern, consolidated Monitoring Architecture V2 that lowers costs, increases quality, and is managed entirely in code.
Inside the rollout
We developed a holistic Monitoring Concept V2 and implemented it end-to-end. The starting point was a dedicated landing zone for monitoring, followed by the implementation of an Azure Data Explorer Dedicated Cluster for performant analyses of large volumes of data. All Data Collection Rules were revised and standardized. Together with the security team, we defined requirements for security logs and their integration into ADX. The alerting landscape was consolidated – fewer but more meaningful alerts instead of noise across all areas. The entire implementation was carried out via Azure Bicep and CI/CD pipelines.
A central monitoring platform was created that is fully versioned in code and sets clear standards for the entire landscape. The consolidated log architecture as well as uniform alerting standards and a Dedicated Azure Monitor Cluster form the basis for reliable observability, less noise with alerts, and significantly faster response times. The solution is reproducible at any time and designed for future expansion.
„More alerts do not mean more security — monitoring that reports everything ends up reporting nothing.“

Consolidated Log Architecture
Learnings
- Organically grown monitoring needs a redesign, not fine-tuning: a consolidated Concept V2 beats years of patchwork on individual rules.
- Fewer but more meaningful alerts improve responsiveness more than any additional metric.
- A dedicated landing zone for monitoring cleanly separates observability from the rest of the landscape and creates clear responsibilities.
- Security logs belong in the monitoring architecture from the start — defined together with the security team, not added downstream.
What's next
The monitoring platform is designed for expansion: new workloads are connected via the standardized Data Collection Rules, and changes flow in versioned via Bicep and CI/CD pipelines. The dedicated cluster provides headroom for growing data volumes and performant analyses. Further evaluations can be built on the consolidated log architecture in the future — from advanced security analyses to the ongoing optimization of ingestion costs.
