This article applies to PRTG Network Monitor 13.3.4 or later

Notification Delivery Logging

Extended notification delivery logging can be helpful to debug issues with the process of delivery. For this reason, we provide a registry key option that allows you to do that. If you apply this registry hack, logs of notification delivery will be stored in your PRTG data directory.

Important: Notification delivery logging is only meant for debugging purposes in case of delivery issues. Activate it only for this purpose. Deactivate it again after usage and delete the log files manually. Otherwise, you might encounter an error in the normal use of notifications: Error sending "xyz": Cannot open file "xyz\Notification Log(xyz)".

Caution: Please back up your system before manipulating the Windows registry!

Steps to Go

  1. Open the registry editor and navigate to the following key:
    1. On a 64-bit Windows system, navigate to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core
    2. On a 32-bit Windows version, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core
  2. Create a new DWORD: in the current path, right-click, choose New | DWORD Value, and name the new value LogNotificationDelivery.
  3. Set the value of LogNotificationDelivery to 1: right-click on LogNotificationDelivery and select Modify…. In the value field, enter 1. Confirm with Ok.
  4. Restart your PRTG core server.
  5. Let PRTG run for a while, so that SMTP relay can take place more than once.
  6. The log files will be generated with their timestamp as name in the following subfolders of the \Logs\debug\ folder in your PRTG data directory:
  • Notification Delivery Debug Log (MX Server)
  • Notification Delivery Debug Log (SMTP Relay 1)
  • Notification Delivery Debug Log (SMTP Relay 2)
  • Notification Delivery Debug Log (HTTP)
  • Notification Delivery Debug Log (SMS)
  • Notification Delivery Debug Log (Amazon SNS) (as of PRTG 15.4.21)

If you encounter issues with notification delivery, please zip the log files and forward us the same.

Setting the value of the DWORD to 0 (or deleting it) will disable notification delivery logging again. Please delete the log files manually after successful debugging.
