FreeSpace is a simple script that scans selected server volumes and
reports on their free space. It also color codes the results to give you
quick - at-a-glance indication if a volume is nearing capacity.
Here's a sample report:
Prerequisites
- Installed and operational web server - tested only with IIS on WinXP
- Perl installed and associated with .PL suffix in PATHEXT environment var
Download the Perl Script
FreeSpace.zip
Containing:
FreeSpace.pl
CheckVersion.pm
Configure the Script
Manually install FreeSpace.pl into any folder. I recommend c:\Tools. The
FreeSpace.pl script requires you to set the name and share for each computer
to be monitored. FreeSpace.pl is a text
file, so you can edit it with just about anything, notepad for instance.
CheckVersion.pm should be installed into the <perl>\site\lib\Version
folder, which you may have to create.
Win32-AdminMisc.ppd must be downloaded and installed. Visit http://www.roth.net/perl/adminmisc/
for the download and instructions for installation.
Testing and Deployment
You can run this script from the command line. If you have perl files
configured properly, you can simply type "FreeSpace" and it will run
and report. If you see the html content, you are ready for automation.
Run as a period Job
Open Control Panel and then Schedule Tasks. Create a new task to run
FreeSpace. A typical command line to do this is
c:\perl\bin\perl.exe c:\Tools\FreeSpace.pl d:\inetpub\www\FreeSpace.htm
This starts perl, gives it the FreeSpace script, and gives that script the
path and name where to publish the results. Note that the third parameter should
be somewhere within your web space.
Configure this script to run every 1 or perhaps every day, it all depends on
how active your servers are.
Run as Admin
In order to access the information on other servers, you must run this script
as an Admin. To minimize the security risk, this script should never be run from
the web space (which likely isn't "Admin" anyway). So it only
publishes a static file to the web server.
Monitor the Servers
I enable active desktop on my main machine. With this, I can embed
FreeSpace.htm in the desktop for easy at-a-glance monitoring. You can configure
a refresh interval so it will be reasonably up to date. Note that the refresh
interval is configured separately from how often you have Task Scheduler set to
acquire the data.
