What is the difference between rules and rules1.14 in Prometheus operator? When is rules or rules1.14 used?

https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack/templates/prometheus .

I see both have same rules but with some differences.Like CPUThrottlingHIGH rule exist in both folders but rules1.14 has it as "info" and rules folder has it as "warning".

1.14 term is referring to the Kubernetes version.

When your Kubernetes version is in 1.10 <= version <1.14, rules from rules directory is created.

You will find the following line at the beginning of every YAML files in the rules directory:

{{- if and (semverCompare ">=1.10.0-0" $kubeTargetVersion) (semverCompare "<1.14.0-0" $kubeTargetVersion) .Values.defaultRules.create .Values.defaultRules.rules.alertmanager }}

Similarly, when your Kubernetes version is in version >= 1.14, rules from rules-1.14 directory is created.

{{- if and (semverCompare ">=1.14.0-0" $kubeTargetVersion) (semverCompare "<9.9.9-9" $kubeTargetVersion) .Values.defaultRules.create .Values.kubeEtcd.enabled .Values.defaultRules.rules.etcd }}
