With CheckSpace you can monitor the free space of one or more harddisk drives or partitions. Also, you can monitor directories, so that it worked like a disk quota. If the drive or directory reach a defined limit, CheckSpace sends a warn e-mail to an user defined address. The event log monitor sends you the new entries by mail if they are written in the log. The Dr. Watson monitor cachts Watson errors and send you a detailed error report if an error occured. That helps you to locate the problem and prevent it for the future. With the application monitor you can check if a specified program is running. If not, you can execute it. If it runs, you can terminate it. The CPU usage monitor controls the CPUs and perform an action when it breaks a limit. The service monitor checks if a service is running. The file monitor controls the file properties and the http monitor checks when your website is on or off error. The HTML Report engine creates tidy and clearly arranged html files with all CheckSpace results. All monitors have a single e-mail notification. With that and the Mail-To-SMS gateway of your provider, CheckSpace can send all warnings on your cell-phone. Because of these and all the other functions, CheckSpace is the ideal tool for Sistema administrators who need to be kept informed about their systems.
