PowerActions integrates the vSphere Web Client and PowerCLI to provide complex automation solutions from within the standard vSphere management client.
PowerActions is deployed as a plugin for the vSphere Web Client and will allow you to execute PowerCLI commands and scripts in a vSphere Web Client integrated Powershell console.
Furthermore, administrators will be able to enhance the native WebClient capabilities with actions and reports backed by PowerCLI scripts persisted on the vSphere Web Client. Have you ever wanted to “Right Click” an object in the web client and run a PowerCLI script? Now you can!
For example I as an Administrator will be able to define a new action for the VM objects presented in the Web client, describe/back this action with a PowerCLI script, save it in a script repository within the Web client and later re-use the newly defined action straight from the VM object context (right click) menu.
Or, I as an Administrator can create a PowerCLI script that reports all VMs within a Data Center that have snapshots over 30 days old, save it in a script repository within the Web client and later execute this report straight from the Datacenter object context menu.
Or better yet, why not share your pre-written scripts with the rest of the vSphere admins in your environment by simply adjusting them to the correct format and adding them to the shared script folder.
