Short description of PA Storage Monitor Pro 3.3: PA Storage Monitor is built to keep track of very large server volumes. It can monitor free disk space and create graphic reports over time, monitor individual files and file owners and create many reports about file age distribution, file owner disk usage, etc. In addition, it can watch files and directories and keep track of their sizes over time, or report whether they have changed as many host based intrusion detection systems (IDS) do.
