Monitoring Server Disc Space

One of the more mundane things that I (and many server admins) have to do is to monitor free disc space on servers. There are a number of expensive tools to do this but I wanted a way to look at the information for all my servers at the same time with the possibility of a small pie chart or some such so that I can glance at it and know whether something needs to be done.

My solution to this was to create an RSS feed so that any major (by my definition) changes to free space would be flagged. I have a little routine that checks all my servers and puts the data into a table in an admin database which I can then query easily. The routine to create the feed was adapted from here and converted to VB. The code is simple and effective and it works.

My feed also links to a page which can show more of the history and any other information I want.
