PRTG Manual: Object Settings
Probe, group, device, and sensor pages have tabs that you can use to navigate between different options. For example, you can view your network's status, view monitoring results, or change settings.
Tabs Bar for Sensors
On the Settings tab, you can define all settings for the selected object. The available options vary depending on the kind of object that you select. See the following sections for information about the object types:
You cannot open channel settings via tabs. Go to a sensor's Overview tab to edit the channel settings.
Notification Triggers Settings
On the Notification Triggers tab, you can set notification triggers for every object. If you use these settings for a probe, group, or device, they are inherited to all sensors on these objects. The available notification trigger options are the same for all objects.
For more information, see section Notification Triggers Settings.
On the Comments tab, you can enter free text for each object. You can use this function for documentation purposes or to leave information for other users.
On the History tab, all changes in the settings of an object are logged with a time stamp, the name of the user who made the change, and a message. The history log retains the last 100 entries.
On some pages, you can click 
in the page header bar to access the history of subordinate objects. This includes system administration settings and account settings, reports, libraries, and maps. For more information, see section Logs.
