DiskPulse Server Disk Space Monitor
DiskPulse Server and DiskPulse Enterprise include a built-in disk space monitor allowing one to monitor the free disk space in a number of disks or directories and provides the ability to send E-Mail notifications and save disk change monitoring reports showing created or modified files and/or execute custom actions when the amount of the free disk space drops below or rises above a user-specified limit.
The disk space monitor is located in the bottom-right corner of the DiskPulse client GUI application. By default, the disk space monitor shows the status of all local disks in the server. For each disk, the disk space monitor shows the disk name, the total amount of the disk space, the amount of the free disk space and the disk status according to the configuration of the disk space monitor.
In order to add an additional disk or directory to the disk space monitor, press the right mouse button over the disk space monitor pane, specify the name of a disk or directory to monitor and press the 'Ok' button. In order to change the configuration of a previously created disk space monitor, select the required disk item in the disk space monitor pane, press the right mouse button and select the 'Edit Monitor' menu item.
For each monitored disk, the disk space monitor allows one to control the disk space monitoring frequency, the maximum number of monitoring errors and disk space monitoring actions and/or E-Mail notifications. Sometimes, when monitoring the disk space usage in remote servers or NAS storage devices via the network, a network server or NAS storage device may be temporary offline due to unexpected connectivity or hardware problems. In this case, the disk space monitor will mark such a disconnected device as 'Offline' and continue to monitor the server according to the user-specified maximum number of errors. On the other hand, if a network server or NAS device was permanently disconnected from the network, the disk space monitor will disable monitoring of the disconnected server after the user-specified number of monitoring errors.
In order to automatically send an E-Mail notification and/or execute a custom action when the amount of the free disk space drops below a user-specified limit, the user needs to configure one or more disk space monitoring actions. Open the disk space monitor dialog, press the 'Monitor Actions' button, specify the minimum amount of the free disk space to trigger the action, select the 'Send Notification' option, select an appropriate notification format and specify an E-Mail address to send the notification to. In addition, in order to enable E-Mail notifications, the user needs to open the main options dialog, select the 'E-Mail' tab and configure an E-Mail server to use to send E-Mail notifications.
In addition to E-Mail notifications, the user is provided with the ability to automatically start a disk change monitoring operation, which will monitor all created or modified files and save disk change monitoring reports in the DiskPulse Server reports database. If the user selects the 'Default Disk Change Monitor Command' option, the disk space monitor will automatically create a disk change monitoring command configured to monitor all disk changes and save disk change monitoring reports in the DiskPulse Server reports database. If the user selects the 'Custom Disk Change Monitoring Command' option, the disk space monitor will execute the user-configured disk change monitoring command. Finally, if the user selects the 'User Command, Script or Batch File' option, the disk space monitor will execute the user-custom command, script or batch file.
