Hi Juju, I have tried status_set(), which will show up in juju debug-log, but how to make some message appear on Juju GUI? I'm building a charm that I want to feedback user of progress. What's the right tool for this? -- Feng xia Engineer Lenovo USA Phone: 5088011794 fxia1 at lenovo.com Lenovo.com Twitter | Facebook | Instagram | Blogs | Forums
