Spider read vnn.vn in 1.9 s without a browser and returned 52 lines of clean markdown, including the section "PRTG Manual: Logs".
# PRTG Manual: LogsThe Enterprise Console has a tab-like interface. Using the tabs you can navigate through various pages with information about your monitored objects, such as your network's status, monitoring results, etc., as well as access maps, reports, and settings.Enterprise Console Menu Tabs BarThere is documentation available for the following tabs:The Logs list shows all past activities and events of your PRTG monitoring setup. This is useful to keep track of all important activities and, for example, to check whether messages were sent, etc. In a typical setup, a huge amount of data is produced here. As the activity of every single object is minuted, you can use this data to check exactly if your setup works as expected.There are two possibilities to call the logs list: Either you click on the Log tab while viewing an object's details in the Devices menu tab, or you choose the Logs entry from the menu tabs bar.Click the Logs entry in the menu tabs bar to show a list of all log entries of a PRTG core server.You can either view the entries of one or all servers. If you have configured more than one PRTG core server and you want to view entries from all servers in your PRTG Servers setup, simply select All PRTG Servers from the server selection in the upper right corner.The background color of a row indicates the value listed in the Status column. It is shown green for Up, yellow for Warning, red for Down, and white for all other values.You can enable a filter to only show certain log entries of a certain event. The drop down menu shows all possible event types. Select an entry to only show events of the respective event type. Choose between All Events, Up & Down, Down, Warning, Unusual, Up, Paused & Resumed, Probe Related, Auto Discovery, Notifications, and Status Messages. The default value is All Events.If you have filtered out all sensors and the list below shows no entries, try another filter or revert to All Events.In the list, one hundred entries are shown at a time. Use the arrow symbols above the list to show other items. You can jump to the beginning of the list, or browse through it hundred by hundred. If the list has more than one entry, you can also sort the items by the contents of a certain column. To sort, simply click once or twice on the header of the column you want to sort by.
