Future saturation recommendation
The Future saturation recommendation detects entities for which the resource usage has either already exceeded thresholds or is expected to exceed the thresholds.
The recommendation is generated by evaluating the natural (organic) growth of resource usage in your cluster due to workload growth, or due to deployment of new projects. It is based on historical trending, and extrapolation to the future. It compares the estimated resource utilization with thresholds.
Based on what might be causing the resource usage to trend upward, you can take specific steps to resolve the problem. Here are some examples of the upward trend scenarios and pointers to resolve them:
|Upward trend scenario||Pointers|
|If any of the hosts in the vSphere cluster are disconnected or are in maintenance mode||Troubleshoot the hosts and recover cluster resources.|
|If the cluster has the High Availability (HA) option turned ON|
In all these cases, troubleshooting the offending hosts should enable you to recover the resources of the cluster and eliminate the future saturation condition.
In all these cases, remove the condition that prevents an available host from powering on to add resources to the cluster and remove the future saturation condition.
|If storage is saturating soon or is already saturated|
|If CPU or memory is saturating soon or is already saturated||If there are Idle VMs in the cluster, consider removing them to reclaim CPU or memory resources.|
|If you are familiar with the workload (application) running inside a VM||Troubleshoot (for example, stop runaway processes) or tune the application to reduce its footprint, then reduce the reservations or limits available to the VM or its parent resource pools to make the cluster more efficient.|
|As a last resort, for CPU, memory, or storage|
