Logs show all past activities and events of your PRTG monitoring setup. This is useful for researching past user activities, system events, and, for example, for checking whether messages were sent. In a typical setup, a huge amount of log data is produced. Because the activity of every single object is recorded, you can use this information to check if your setup works exactly as desired.

Several filters are available for navigating the log entries.
