The following is a list of environment variables that can be requested for Windows devices via the systray icon's help request form. The steps for returning MacOS environment variables are listed as well.
Important Note: The example below pulls the variables directly from Windows, so NinjaOne does not have any control over which variables do and do not exist.
To display a list of set environment variables:
Windows
- Go to Start > All Programs > Accessories > Command Prompt.
- In the command prompt, enter set. A list of all the set environment variables displays in the command window.
MacOS
- Launch Terminal or a shell.
- Enter printenv. A list of all the environment variables that are set is displayed in the Terminal or shell window.
