Enhancing Prometheus Adapter Configuration for Multiple Config Files

Problem:

The client seeks guidance on passing multiple configuration files to Prometheus Adapter (P8s) version v0.11.1 without encountering size limitations or performance issues. They aim to aggregate custom metrics efficiently across microservices in Kubernetes.

Process:

The experts discussed various aspects of configuring Prometheus Adapter, addressing concerns such as size limitations with config maps and optimizing performance with multiple custom metrics. Recommendations included converting config maps to JSON or splitting them into smaller files to manage size constraints effectively.

Solution:

Adding Multiple Config Maps: Test the capability of Prometheus Adapter to handle multiple config.yaml files simultaneously.
Size Optimization: Reduce the size of config maps by converting to JSON format or splitting into smaller files to avoid reaching the 1MB limit.
Handling Custom Metrics: Explore solutions for managing and scaling custom metrics across microservices, ensuring efficient resource utilization.
Testing in Sandbox: Edit deployment templates and add additional config maps in a sandbox environment before deploying changes to production to ensure compatibility and stability.
Environment Setup: Establish an environment to demonstrate the functionality of custom metrics and test changes in deployment templates to validate their effectiveness.

Conclusion:

By following these steps, the client aims to enhance their Prometheus adapter configuration to handle multiple config files effectively. Testing and iterative improvements will help ensure scalability and optimize resource usage within their Kubernetes environment.
