Ensuring that monitoring systems are scalable allows you to monitor your Kubernetes cluster effectively, even as it grows and changes over time.

As your Kubernetes cluster grows, the amount of data that it generates will also increase, and your monitoring systems need to be able to handle this increase in data. If your systems are not scalable, they may become overwhelmed by the volume of data and may not be able to provide accurate or useful information.

In addition, having sufficient data retention is important because it allows you to retain and access historical data from your cluster. This can be useful for troubleshooting problems that occur, as well as for understanding trends and patterns in your cluster’s performance over time.

Data retention is also important for compliance because many regulatory frameworks, such as the General Data Protection Regulation (GDPR), require organizations to retain specific types of data for a certain period of time.
