Configure a File Age Check

A File Age Check monitors when a file was last modified. This is useful for verifying that backup files, log files, or data exports are being created on schedule.

Prerequisites

• You need the Monitoring Check Management permission.
• The target device must have a connected agent.
• The agent must have read access to the monitored file paths.

Steps

1. Go to Devices and open the device.
2. Click the Checks tab → Add Check → File Age.
3. Add one or more file paths, each with its own thresholds:

4. Choose what happens if the file does not exist:
   • Warn if file is missing (default: Yes) — Warns if the file is not found
   • Critical if file is missing — Critical if the file is not found
5. Click Add Check to save.

What the check reports

The check reports the last modification time and age for each monitored file, or a missing alert if the file does not exist.

Tips

• Use this check to verify that automated processes (backups, exports, log rotation) are completing on schedule.
• Set the thresholds based on the expected update frequency. A daily backup file should warn at 24 hours and go critical at 48 hours.
• On Linux, use forward slashes in paths (e.g. /var/backups/daily.sql.gz). On Windows, both backslashes and forward slashes work.

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