Observer Analyzer : Observer Analyzer : Getting Started : Virtual machine troubleshooting : Cannot capture traffic using VMware ESX VM
Cannot capture traffic using VMware ESX VM
When using GigaStor Software Edition in a virtual machine, Observer cannot capture network traffic when Memory Hot Add is enabled.
 
When Memory Hot Add is enabled, Observer can see traffic as a blue line, but Observer cannot capture any traffic by manually starting packet capture or being set to always capture data. You can still reserve memory in Observer (for example: 12 GB of 16 GB), and Observer states that it has reserved 12 gigabytes of memory; however, Windows does not actually reserve the memory. Windows views all 16 GB of memory, from our example, as available to the operating system. The result of this behavior is that Observer cannot capture data.
 
 
A solution for this issue is to Disable memory hot add for this virtual machine in your virtual machine settings. The process for disabling memory hot add is described in How to disable memory hot add.
 
How to disable memory hot add
Memory hot add lets you add memory resources for a virtual machine while the machine is powered on.
Prerequisite(s):  
VMware Tools must be installed.
The guest operating system supports memory hot add.
The virtual machine uses hardware version 7 or later.
 
Follow the steps outlined in the vSphere Documentation.
Ensure Disable memory hot add for this virtual machine is selected in the VM properties.
This means the feature is disabled.

Memory hot add is now disabled. You should now be able to capture traffic.
