Scripting UCS FI 2.x NX-OS Commands

[JohnathanPaul]

Has anyone successfully scripted UCS 2.x NX-OS commands (such as show system uptime, and show platform software cmccrtl process meminfo | i MemFree) that can be run across multiple domains which passes credentials?  Apparently cannot be done using PowerTools.  It would be helpful to regularly run certain commands that do not exist in PowerTools to assess the health of memory usage and system up time.

I do not know how robust this solution will end up but you can run ssh commands from powershell using WMF 5 and the Posh-SSL Cmdlets.
