Deploying the OMS Agent Automatically
I needed to deploy a new OMS workspace to every machine in my environment and these machines were at various states of configuration. Some had the OMS agent already installed, some had various workspaces already added and some had the new OMS workspace already configured. Additionally these machines were in different environments with differing access to file services where the agent could be stored.
Therefore I created a script that downloads the agent from the Internet if its not already installed, checks if the desired workspace is already configured and adds if its not.
Update the workspace ID and Key to that of your environment.
