3 Prometheus is the underlying technology used for metrics.
4 This does not apply to physical disk, VM physical disk, VMDK, loopback over NFS, AWS EBS, and Azure Disk.
5 For metrics, using file storage with the ReadWriteMany (RWX) access mode is unreliable. If you use file storage, do not configure the RWX access mode on any PersistentVolumeClaims that are configured for use with metrics.
6 For logging, using any shared
storage would be an anti-pattern. One volume per elasticsearch is required.
7 Object storage is not consumed through OpenShift Container Platform’s PVs/persistent volume claims (PVCs). Apps must integrate with the object storage REST API.
