Minding the store

In the past month Mark-my-unidicted-co-conspriator has been bitten a couple of times by servers under his team's care running short of disk space. I was thinking about this a couple of days ago — something along the lines of "what Mark needs to do is write a little VB [Microsoft Visual Basic] app that uses WMI [the Windows Management Interface] to connect to the servers and pull disk stats". Then I realized that if Mark had the time to write said little VB app he would have done it already.

Well, I don't know next to nothing about VB or WMI programming. But I do know Perl and I have Samba (the package that lets Unix/Linux boxes act like Windows file servers). A quick search on cpan turned up a module that lets me drive the Samba client from within a Perl scrip. Retreiving disk space statistics is one of the basic functions the Samba client can perform.

A couple of hours of hacking later and SpaceCadet was born. It's running once a day through cron on my NMS box. It pleases my sense of guerilla justice that I'm now minding the health of a herd of Windows 2000 servers from my little Linux box.

Mark gets back tomorrow from a couple of days off ; hopefully he'll find this a welcome surprise.
