How to use vSAN Observer

1/ SSH somewhere where you have RVC. It can be for example VCSA or HCIbench appliance

ssh root@vc01.robo-p6.uw.cz

2/ Run RVC command-line interface and connect to your vCenter where you have vSphere cluster with vSAN service enabled

rvc administrator@vc01.robo-p6.uw.cz

3/ In RVC CLI go to your vSphere cluster with vSAN service enabled

cd localhost/
cd ROBO-P6
cd computers
cd vSAN

4/ Start vSAN Observer

vsan.observer ./ --run-webserver --force

or one-liner

vsan.observer -r /localhost/ROBO-P6/computers/vSAN

5/ Go to vSAN Observer web interface

vSAN Observer is available at https://[IP-ADDRESS-OF-RVC-HOST]:8010

In my case, it is running at https://vc01.robo-p6.uw.cz:8010
