Hudson is a great tool, and the emails it sends about failing builds are a great help. However, it can only do this if Hudson itself is in a working condition. It is able to report problems with its own executors like low disk space, unsynced clocks etc. on the web interface, just as it reports build problems, but I couldn't find an option to send email alerts about these. Yet it would be so useful, and seems so logical that this feature should be there.
Am I looking at the wrong place to fix this? Is there another solution to learn about problems with executors without having to poll the web interface every now and then? Am I missing something?
