Some XML files are generate on one server and comes to other server. The script and path is set in a different application log file. When they are coming to 2nd server, in case the disk space of the server is less than the files size, the file is not getting saved properly.It shows 0 KB. Can you provide a tool or script which will evaluate the size of the file and space of the server .. Once the server space is less than the files size it should send a alert. Alert by email is better.
