红帽全球峰会10.3.2. 先决条件
根据您的缩放目的地，计算并为 Prometheus 数据存储设置相关 PV 大小。由于默认的 Prometheus pod 副本为 2，因此对于具有 3600 个 pod 的 100 个节点，您将需要 188 GB。
例如：
195 GB (space per 15 days ) * 2 (pods) = 390 GB free
195 GB (space per 15 days ) * 2 (pods) = 390 GB free
根据此公式，设置 openshift_cluster_monitoring_operator_prometheus_storage_capacity=195Gi。
