The customer is requesting this feature for several reasons, primarily centered around enhancing their use of the Kubernetes Vertical Pod Autoscaler (VPA) by integrating it with Prometheus:

1. Enhanced Monitoring and Reporting:

• • By configuring Prometheus as a history provider for VPA recommendations, the customer can leverage Prometheus' robust monitoring and alerting capabilities. This allows them to create detailed dashboards and visualizations, providing better insights into the performance and resource utilization of their applications.

1. Centralized Data and Metrics:

• • Prometheus is a widely used monitoring system in Kubernetes environments. Integrating VPA with Prometheus means that the customer can have a single source of truth for all their metrics and monitoring data. This centralization simplifies management and enhances the consistency of the data.

1. Improved Decision Making:

• • With VPA recommendations available in Prometheus, the customer can make more informed decisions about resource allocation and scaling. This is crucial for optimizing application performance and cost-efficiency.

1. User Recommendations:

• • The customer wants to provide VPA recommendations to their users. By exposing these recommendations through Prometheus, users can access them easily, enabling them to optimize their own workloads based on reliable data.

1. Operational Efficiency:

• • Adding the ability to configure Prometheus in the operator subscription streamlines the operational workflow. This feature would simplify the setup process, making it easier for the customer to deploy and manage their Kubernetes environments.

In summary, the customer needs this feature to improve their monitoring, reporting, decision-making processes, and overall operational efficiency by integrating VPA recommendations with Prometheus.
