Chapter 3. Resource optimization for OpenShift optimization reports

To receive resource optimization recommendations for your namespaces, you must first enable each namespace. To enable a namespace, label it with insights_cost_management_optimizations='true'.

In the CLI, run: oc label namespace NAMESPACE insights_cost_management_optimizations="true" --overwrite=true

After you select an optimization, you can toggle between two tabs called Cost optimizations and Performance optimizations. Optimizing for cost uses less resources and is useful when you are performing tests where there is no impact to users. Optimizing for performance provides all the resources possible and is helpful for apps running in a production cluster.

In Cost optimizations, recommendations get generated when CPU usage is at or above the 60th percentile and memory usage is at the 100th percentile. In Performance optimizations, recommendations get generated when CPU usage is at or above the 98th percentile and when memory usage is at the 100th percentile.

On the Optimizations page, there are two box plots for your Current CPU utilization and your Current memory utilization. These visualizations can help you understand resource distribution and identify outliers in your data. You can export the data in CSV and JSON format.

The box plots display the following data points in millicpu (m) for CPU and in mebibytes (Mi) for memory:

The data points are based on the time period that you selected:
