PATROL KM for UNIX enables you to monitor memory statistics of a VMware virtual (guest) machine by using the following VMware parameters. These parameters are available only if VMware tools are installed on the Linux virtual machine (guest machine). They are not available for the remote host.
VMware parameters to monitor memory statistics
Displays the estimated amount of memory the virtual machine is actively using.
Displays the amount of memory that has been reclaimed from a virtual machine through the VMware memory balloon mechanism.
Displays the maximum amount of memory that is allowed to a virtual machine. Assigning a memory limit ensures that a virtual machine never consumes more than a certain amount of the allowed memory. By limiting the amount of memory consumed, a portion of this shared resource is allowed to other virtual machines.
Displays the mapped memory size of a virtual machine. This is the current total amount of guest memory that is backed by physical memory.
This mapped memory size might include pages of memory shared between multiple virtual machines and therefore, might be an overestimate of the amount of physical host memory consumed by this virtual machine.
Displays the amount of overhead memory associated with a virtual machine that is consumed on the host computer.
Displays the minimum amount of memory that is guaranteed to a virtual machine. Assigning a memory reservation ensures that even as other virtual machines on the same host consume memory, a certain minimum amount is still available for this virtual machine.
Displays the amount of physical memory associated with a virtual machine that is copy-on-write (COW) shared on the host.
Displays the estimated amount of physical memory on the host saved from COW shared guest physical memory.
Displays the amount of memory associated with a virtual machine that has been swapped by ESX.
Displays the estimated amount of physical host memory currently consumed for a virtual machine's physical memory. This memory is calculated as follows: (Memory Mapped in MB) - (Memory Shared Saved in MB)
