remove not updated charts after some time

[RobbScarlet]

Hi,
If I do not need a chart, how can I delete it.
I want to delete the chart which do not collect data after 10 minutes, and let it not display on the dashboard.

I had such code in netdata, but I see I have disabled it for some reason and I can't remember why.

I can re-enable it, but I would like to make a few tests first. So, I'll leave this open.

Currently netdata team doesn't have enough capacity to work on this issue. We will be more than glad to accept a pull request with a solution to problem described here. This issue will be closed after another 60 days of inactivity.

@cakrit we could mark non-collected charts as OBSOLETE after some time and the code will clean them up.

Cleanup is already taking place when a chart is created. So, a new chart has to be created for the old charts to be deleted. Before cleaning up, we could mark as obsolete all the charts that have not been updated for some time (user configurable). Seems pretty simple to do.

The collectors now have the ability (and responsibility) to mark both charts and dimensions as obsolete. So if we have specific examples of charts that should be removed, we need to create an issue for those collectors.

Charts can be obsoleted using the obsolete option in an external plugin. The documentation is here. For an internal plugin the rrdset_is_obsolete() function should be used.

I believe we can close this one, let us know if you need more help.
