From Aesgard Technologies:

Are you an over-worked network administrator? Get calls complaining about system outages you have no way of monitoring? Are you sufferring from server crashes or data loss due to lack of hard drive space? SpaceMon makes it easy to watch network storage space and alert you from your current network monitoring package* or simply rely on notification email sent by SpaceMon when a resource dips below the amount of free space you specify. Get SpaceMon and get some sleep, you deserve it.

Simply type in the resources you want monitored (drive letters or UNC paths) and the level of free space you want to be alerted at. That's it! If any one of the network resources dips below the alert level you set, you will be notified visualy, audibly, by email and through your current network monitoring tool*.

*Suggested network monitoring tools include: What's Up Gold & Servers Alive
