Performance Monitoring
Virtual Machines share host resources, so performance issues can be cause by either the virtual machine’s not having enough
resources or by reaching the physical resource limit on the the virtual machine’s host The vSphere client provides some several tools
to evaluating performance problems on both the virtual machine and host.
VM Performance Tab
There are several indicators that should be checked if the exacqVision Virtual appliance has performance issues. You must consider
the CPU performance of both the virtual machine and the host. The Performance tab can provides a quick indicator of performance
issues.
To monitor virtual machine performance, open the VMware client and navigate to Host and Clusters. Select the exacqVision Virtual
machine in the Inventory pane, select the Performance tab, and choose the 1 Day time range. From the Overview screen, view the
CPU (%) graph. If the average is above 80%, consider adding a virtual CPU to the machine by editing the machine settings.
Also note the memory balloon and swap-out rates. These indicators should be at or near zero. Values in these charts indicate
memory limit placed on the virtual machine or memory overcommitment. A value of 6% or less of memory free on the host indicates
overcommitment of memory resources.
Scroll down the page to view the memory percentage. The exacqVision Virtual server defaults to 2GB of RAM with a reservation of
2GB. If this value averages above 80%, consider adding memory resources to the virtual machine. If this is a small deployment and
this number is consistently below 50%, you might be able to reclaim some host resources by lowering the memory reservation.
NOTE: Usage of the exacqVision Web Service will dramatically increase CPU and memory demands on the virtual machine.
