I don't want to use ssh method or log in to the DCUI , that's why this article not relevant for me.
I would like to write a script for monitor the disk space from outside the vmware enviroment.
The point I'm making is that to get the information I think you are looking for even VMware suggests using SSH or DCUI. There is no mention of being able to do this using PowerCLI or via Web-Client. Usually their KBs list all possible methods of achieving a task, SSH, PowerCLI, Web-Client. They didn't do that here, suggesting it isn't easily possible.
I have used POSH-SSH in PowerShell before to access the ESXi CLI. This works quite well.
You are right, log in with ssh is the quickest and easiest for investigate space problem. My aim is little bit different and I have limitations (ssh disabled) that is why need another approach.
I read the most knowledge base article and find some commands, but not the the exact one. I think it is possible query without ssh, I hope somebody know it here :-)
My suggestion for what it is worth:
- Activate SSH via PowerCLI.
- Use POSH-SSH run "df -h" and retrieve results.
- Deactivate SSH.
