On top of HTML5 based Prism GUI, Nutanix cluster has nifty web pages to give additional information on what is going on in your cluster. Under normal conditions there isn’t usually need to access these pages, but they can be handy in troubleshooting or in performance testing. By default these pages are not accessible, as they are firewalled with iptables rules. Example of such page is 2009 page, which contains information about I/O requests that process called “Stargate” handles.
Enabling access for a single Controller Virtual Machine (CVM)
You can allow access to these pages by modifying iptables rules per controller virtual machine (CVM) basis.
