PRTG Manual: User Interface
On the User Interface tab, you can define global settings regarding the PRTG web interface, PRTG web server settings and performance, Geo Maps, and graph settings.
This documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.
If 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.

|
Connection Security |
Specify the security level to use for connections to and from the PRTG web server: ▪High security (TLS 1.2): Only accept high security connections from clients like web browsers, apps, PRTG Desktop, or API clients. ▪Default security (TLS 1.2) (recommended): Only accept high security connections from clients like web browsers, apps, PRTG Desktop, or API clients. ▪Weakened security (SSLv3, TLS 1.0, TLS 1.1, TLS 1.2): If you have clients that do not support High security (TLS 1.2) or Default security (TLS 1.2) (recommended), temporarily use this setting so that they can connect. This setting accepts SSLv3, TLS 1.0, TLS 1.1, and TLS 1.2 connections.

Active IP Address/Port Combinations |
Shows all active combinations of the IP addresses and ports on which the PRTG web server listens for web requests.

PRTG shows several graphs on the Overview tabs and x Days tabs of objects in the PRTG web interface. PRTG keeps these in RAM for fast graph display. The longer the time frames and the shorter the intervals are, the more memory PRTG uses for this. You can adapt the details for all four graphs. This setting also changes the caption of the graphs and tabs in the PRTG web interface and PRTG Desktop.
If you change this setting, PRTG needs to restart the PRTG core server to apply your changes. After you click Save, a dialog box appears that asks you to confirm the restart. Click OK to trigger the restart. During the restart, all users of the PRTG web interface, of PRTG Desktop, or of PRTG Apps for Mobile Network Monitoring are disconnected and reconnected.

Live Graph |
The live graph does not have a fixed time span but you can define how many values to display. The actual time span that the live graph covers depends on the scanning interval of the sensor that you view. PRTG automatically calculates the time span. The default is 120 Values. This results in a graph that covers a time span of two hours if a sensor has a 1-minute scanning interval. Other scanning intervals result in graphs that cover different time spans. Choose from: ▪60 values: Cover a time span of one hour if a sensor has a scanning interval of one minute.
▪120 values: Cover a time span of two hours if a sensor has a scanning interval of one minute. ▪240 values: Cover a time span of four hours if a sensor has a scanning interval of one minute. ▪480 values: Cover a time span of eight hours if a sensor has a scanning interval of one minute. ▪960 values: Cover a time span of 16 hours if sensor has a scanning interval of one minute.
|
Graph 1 |
By default, this is the 2 days graph in the PRTG web interface. You can change it to have more or less detail. PRTG averages the monitoring results of the actual scanning intervals of the sensors. Choose from: ▪1 day with averages of 1 minute: Cover a time span of one day with averages of one minute. This results in 1440 values. ▪1 day with averages of 5 minutes: Cover a time span of one day with averages of five minutes. This results in 288 values. ▪1 day with averages of 15 minutes: Cover a time span of one day with averages of 15 minutes. This results in 96 values.
▪2 days with averages of 1 minute : Cover a time span of two days with averages of one minute. This results in 2880 values.
▪2 days with averages of 5 minutes: Cover a time span of two days with averages of five minutes. This results in 576 values. ▪2 days with averages of 15 minutes: Cover a time span of two days with averages of 15 minutes. This results in 192 values. ▪4 days with averages of 1 hour: Cover a time span of two days with averages of one hour. This results in 96 values.
|
Graph 2 |
By default, this is the 30 days graph in the PRTG web interface. You can change it to have more or less detail. Choose from: ▪10 days with averages of 1 hour: Cover a time span of 10 days with averages of one hour. This results in 240 values. ▪20 days with averages of 1 hour: Cover a time span of 20 days with averages of one hour. This results in 480 values. ▪30 days with averages of 1 hour: Cover a time span of 30 days with averages of one hour. This results in 720 values. ▪30 days with averages of 6 hours: Cover a time span of 30 days with averages of six hours. This results in 120 values.
▪40 days with averages of 1 hour: Cover a time span of 40 days with averages of one hour. This results in 960 values. ▪40 days with averages of 6 hours: Cover a time span of 40 days with averages of six hours. This results in 160 values. ▪60 days with averages of 1 hour: Cover a time span of 60 days with averages of one hour. This results in 1440 values.
▪60 days with 6 hour averages of 6 hours: Cover a time span of 60 days with averages of six hours. This results in 240 values. |
Graph 3 |
By default, this is the 365 days graph in the PRTG web interface. You can change it to more or less detail by choosing a time span covered and a monitoring interval average associated with it. Choose from: ▪100 days with averages of 1 day: Cover a time span of 100 days with averages of one day. This results in 100 values.
▪200 days with averages of 1 day: Cover a time span of 200 days with averages of one day. This results in 200 values. ▪365 days with averages of 1 day: Cover a time span of 365 days with averages of one day. This results in 365 values. ▪400 days with averages of 1 day: Cover a time span of 400 days with averages of one day.
