Directory Monitoring

Directory Monitoring allows you to monitor the size of a directory and trigger alerts when the total size of a directory is either above or below a set limit. You can also specify whether you would like to monitor the physical or the logical size of a directory, and whether to include sub directories.

Directory Monitoring is part of the Disk Space system health object, as such you can either add a folder to an existing system health package that contains a disk space object, or create a new system health package / disk space object.

Adding to an existing object

To add this feature to an existing system health package, simply select the "Disk Space" object in the system health package and click the Directory Monitoring tab.

Creating a new system health package

Create a new system health package by right-clicking the "System Health Packages" container and add a new "Disk Space" object to the package by right-clicking the package and selecting "Add". You can also select an existing system health package that already contains a "Disk Space" object and click it in the left pane.

Since the package is only going to be used to monitor directories, set the disk space monitoring feature ("Logical Disks" area) to "Do not monitor any drives". Then, click the "Directory Monitoring" tab.

Database

Specify the database that will be used when a directory is configured to record the current size to the central database.

Monitoring a Directory

To monitor a new directory, click the + button or double-click an existing directory.

Directory

Select the directory you want to monitor, you can use environment variables such as %SYSTEMROOT%.

General

Specify the size limit of the folder, if you need to get alerts when the size of the directory falls below or exceeds your threshold.

Also specify whether the size of the folder should be calculated using the physical size or the logical size of the files. Since hard disk are arranged in sectors, the physical size is usually slightly larger than the logical size, with the exception of folders that have compression enabled. Those directories will usually have a smaller physical size, as such the default and recommended setting is to calculate the physical size.

Specify how often the agent should check the directory. Since calculating a directory size can be resource intensive on larger directories, set this interval appropriately.

Check the "Include Sub Folders" check box to include sub directories in the total size calculation.

Actions

Log to Event Log as: Logs an alert to the application event log with the specified severity when the configured threshold is exceeded, see Event Log for more details on events that can be logged by this feature.

Log to Database: Records the current directory size to the database selected in the parent dialog.
