This rule fires an alarm to report that when a virtual machine within the cluster is requesting CPU cycles from the ESX Server on which it is running, it is not receiving them some percentage of the time. This impacts the performance on the virtual machine.
This rule fires an alarm to report that if an ESX Server within the cluster fails, the remaining servers in the cluster may not or do not have enough available CPU and/or memory to handle the increased workload.
Although the cluster can handle the failure of a single ESX Server, either the resulting combined CPU utilization or the resulting combined memory utilization on the remaining servers, or both, would be beyond the warning threshold. The resulting alarm message will indicate the values of both of the new combined utilizations.
If an ESX Server within the cluster fails, the remaining servers do not have the capacity to handle the increased workload. The resulting alarm message will indicate the values of both of the new combined utilizations.
This section lists and describes the datacenter rules. These rules are disabled by default, and can be enabled as required.
