Disk storage trend software - suggestions?
 

Does anyone know of software I can use to track (historically) disk usage on servers?

I've looked at Space Observer, Disk Space Manager, and WatchDisk. Space Observer is the best but inconsistent re. stability and the GUI.

I want to automatically scan drives and folders and store the sizes for comparison a week from now, a month, a year, etc.

I'm not familiar with those programs, are they for Windows? If you're using a linux server then it's as easy as putting in your crontab a du command that echoes to a text file.

Edit:

After examining these programs I think my solution is probably not what you're looking for. Sorry.

Thanks for your thoughts.

Looks like it might be time to build something. I'm surprised none of the sysadmins here have had a similar need.

"Some call it the industry standard data logging and graphing application. Others use it to write their very own full custom monitoring scripts. Most people will probably get in touch with RRDtool through some third party monitoring applications.

RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it can create beautiful graphs. It can be used via simple shell scripts or as a perl module."

Storing and graphing is the tough part and this seems to take care of it pretty easily. Thanks!
