The cron jobs write to a log file which is overwritten each time. Errors should be detected and reported promptly by PingMyBox, but since the jobs run frequently, it can be difficult to recover the full log before the next run occurs. Generally the error message is sufficient to debug the issue, but there may be other relevant info in the log.
I wonder whether it would be worth having a cumulative log as well? Alternatively, perhaps the status app could save a copy of any log in which it detects an error? Such copies should be in a separate directory to make error detection easier. There would also need to be a way to delete older copies once they have served their purpose. Thoughts?
