We are currently evaluating jira cloud and therefore also testing the asset discovery.
I would be interested on how you do it, because the atlassian discovery tool uses very old .net libraries and therefore needs sha1 (ssh-rsa as algorithm) to be enabled.
For our windows clients that is not such a big deal, we could install there on every client an agent.
But for getting the data from the linux machines, i would need to connect (because installing mono on every server seems to be also a bit junky.
How do you get your data? Or do you use any other discovery agent (like ocs) and did connect it to jira assets?
Very interested in your feedback.
