PowerShell, Confluence : Simple hardware audit but pushed into Confluence

Ok here is a big one for you. Its in functions so you should be able to split it out and use the bits you need pretty easily.

This does a basic machine audit and then uploads the information into a table on a confluence page. It also creates a new page for every server audited.

Im not going to explain it in too much detail. If you need more help please get in touch.

$ServerNames = 'Server1','Server2' #You could (should) get this from AD

$SpaceID = 'ID' #The ID of confluence space (mine just happens to be called ID

function Bypass-CertErrors # you may have gone to the trouble to do this properly. I haven't
