The VM Memory Usage % displayed in Aria Operations is higher than the value shown in the VM Guest OS Task Manager
Aria Operations 8.x
The observed discrepancy between the VM Memory Usage % displayed in Aria Operations and the value shown in the VM Guest OS Task Manager is due to the different data collection methods employed by each tool
The displayed VM Memory Usage % in Aria Operations is accurate and reflects the correct memory utilization of the virtual machine. The difference in values between Aria Operations and the Task Manager is not a cause for concern.
The Virtual Machine Memory Usage (%) metric is calculated using the following formula: VM Memory|Usage (%) = Guest|Needed Memory (KB) / Memory|Total Capacity (KB) * 100
Note: the Memory Usage metric seen in vSphere is different and corresponds with the "Memory|Consumed (%)" and "Memory|Balloon (KB)" in Aria Operations.
Example:
Note: For a combined memory metric that includes both Guest OS, vSphere and ESXi memory configuration please refer to the "Memory|Utilization (KB)" metric which combines:
