We currently use Express Metrics for asset tracking and although I don't like it, the premium feature is being able to track software usage and reconsolidate licences.
I realise this may need a client/service installed on the machine which isn't ideal.
However is this something being considered? It would attract our custom.
Software usage information is not currently collected. This feature is on our customer wish list, but we do not yet have a release date for it. Scanning software usage information would require monitoring software on your client machines and Lansweeper currently performs its scanning agentless.
