What are the rules for monitoring VMware ESX server memory utilization?
해결 방안
VMW ESX Server Balloon Memory Deflation Purpose This rule monitors for servers working excessively to reclaim memory. To better balance memory utilization across servers within a cluster, you can add more physical resources to a server or you can use VMotion to move a virtual machine from one server to another.
VMW ESX Server Consumed Vs. Granted Memory Purpose This rule compares the amount of memory that is being requested by the virtual machines on an ESX Server to the amount of memory available on the ESX Server. If the application workload of the ESX Server is requesting an excessive amount of the available memory resources, you must either add memory to the ESX Server or use VMotion to better balance the virtual machines across the servers within the cluster.
VMW ESX Server Heap Free Memory Purpose This rule monitors heap memory in the vmkernal and fires an alarm when the heap memory for a particular ESX Server drops below a predefined amount. If the amount of heap memory in the vmkernal for a particular ESX Server drops to the critical level, you may want to add more physical memory to the server or use VMotion to better balance memory utilization across servers within the cluster.
VMW ESX Server Memory Estimated Fill Time Purpose This rule determines when the ESX Server memory is likely to reach its capacity, based on its present growth rate.
VMW ESX Server Memory Utilization Purpose This rule monitors for spikes and dramatic drops in memory utilization for an ESX Server.
VMW ESX Server Memory Utilization Upward Trend Purpose This rule monitors for upward trends in memory utilization for an ESX Server.
