Martin-

Super idea.

I think we could show a few more things in the Server tab -- including the persistence subsystem status and any rebind issues -- but following the pattern you describe where these individual components have a sensor/effector api and use the same gui representation.

Hi Folks,

I hit an issue with a customer installation where the disk had filled up as
the nohup.out file created by the launch command in the docs had grown
until it filled the disk. I've created a PR here[1] for this issue

It was also suggested that it would be nice to have some way to indicate
the issue (or other potential issue) in the GUI. I've did a quick spike
here [2] of a mechanism for making this available via the REST API

I was discussing it with @aledsage, and he suggested that some work had
been done at some point to represent the Brooklyn server itself as an
Entity. This would then allow us to follow the sensor-effector-policy
pattern that we use for deployed blueprints. Anyone have any thoughts on
this?

As for how it would be displayed in the GUI, I think that simply adding it
to the 'Application' list would be confusing, but we could add another
top-level tab for 'Server', which would then have the usual 'Summary',
'Sensors', 'Effectors' etc tabs. Hopefully we could re-use some of the GUI
code (@samcorbett, would this be practical?) and we could follow the same
pattern for the API. Again, anyone have any thoughts on this?
