A Folder Size Check monitors the total size of a directory and warns when a threshold is exceeded. This helps you detect runaway log files, cache growth, or uncontrolled data accumulation before the disk fills up.

Prerequisites

  • You need the Monitoring Check Management permission.
  • The target device must have a connected agent.

Steps

  1. Go to Devices and open the device.
  2. Click the Checks tab → Add CheckFolder Size.
  3. Add one or more directories to monitor:
FieldExampleDescription
Folder pathC:\inetpub\logsThe directory to monitor
Warning threshold (GB)50Warns if the directory exceeds this size in GB
Critical threshold (GB)100Critical if the directory exceeds this size in GB
  1. Each folder you add has its own thresholds. The Include subdirectories toggle is global and applies to every folder in the check. It is enabled by default — disable it if you only want to measure top-level directories.
  2. Click Add Check.

Tips

  • Commonly monitored directories: application log folders, temp directories, user profile directories, and database data paths.
  • The check calculates the directory size by summing all file sizes. It runs once every 60 minutes by default, so even for very large directories (millions of files) a single folder walk normally finishes well within the interval — expect the result to update less frequently than with faster checks.
  • Combine this check with a disk space check for complete storage monitoring. The disk space check tells you when the drive is filling up; the folder size check tells you what is filling it.

After the first check interval, the result appears in the device's Checks tab.
