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, to check 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.

There are several filters available to make navigating the log entries easier. See the Working with Table Lists section for more information.

There are two options to open the logs list: Either you click the Log tab on the detail page of a probe, group, device, or sensor, or you choose the Logs item in the main menu.

Probe, group, device, and sensor pages have tabs that you can use to navigate between the different options. For example, you can view your network's status, view monitoring results, or change settings.
