FrameFlow's Directory Event Monitor can alert based on the number of files present in a specified directory, the total number of files, and the total size of all files. It can also optionally check for the presence of the directory. All you need is a username and password that corresponds with the directory you want to monitor. The Directory Event Monitor's setup is simple: it just takes two minutes to begin monitoring and alerting on your directory's metrics.
