Currently I wonder whether my usage of this plugin is wrong. For a new app (or a new version of an app) I typically do the following:

1. I install the app (or new version) on the slaves.
2. I change the inline Groovy code (at "Configure system") to support app/new version.
3. I test it there.
4. For all my slaves I then do
   1. disconnecting the slave
   2. reconnecting the slave
   3. wait until detected labels are updated

Now I wonder whether I can avoid the disconnect-reconnect steps. Can I trigger the app detection for a slave while keeping it connected? Maybe by using some Groovy code from within the "Script Console"?

Or can I run the app detection automatically on a regular base, e.g. once each hour?

Or is my depicted procedure completely wrong?
