I am having an issue with vSAN Observer.
Starting the service using this command: "vsan.observer . --force --run-webserver" I can´t see any information on the website.
The tabs are blank and not brings any information, except the about one, which shows info about my host's models and hardware.
In the logs, while the command is running I can´t see any error, and I have checked out there is no proxy between the terminal server where I am browsing the website using chrome. Even the TS has an IP address in the same network as vCenter.
I can see in the logs: Query VM properties: 16.27 sec (3243 VMs), so the information is there but is not showed at all.
I will attach an image to show how I see the web.
I might be wrong, but vSAN Observer seems to be deprecated
Instead you could see the graphs directly in the vCenter WebClient under vSAN, Support, Performance for Support.
