Website |
|
---|---|
PRTG Site Name |
When using the web interface, the site name is shown in the title bar of your browser window. It is also used by default in notification emails. Please enter a string. |
DNS Name |
If your PRTG web interface is (additionally) reachable via a DNS name, please enter it here. It is e.g. used by default in notification emails to generate links. Please enter a string. |
Website Language |
Choose the system language from the drop down menu. Default is English. Depending on your installation, you may be able to choose other languages here. This setting will influence the language of the Ajax and the Mobile Web GUI web interfaces, as well as of the PRTG System Administration Tools. Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |
Graph Type |
Select how graphs will be displayed throughout the web interface and in reports.
We recommend using area charts, as they're better to read. Note: Graphs containing data from more than one cluster node will always be displayed with line charts automatically. |
Geo Maps |
|
---|---|
Map Service Provider |
Select if and how you want to integrate the Geo Maps feature into the web interface. If enabled, PRTG uses the first line of the location setting of an object to show it on a geographical map. Please choose a map provider:
For more information about the different map providers, please see the More section below. |
Map Type |
This setting is only visible for some map providers. Depending on the chosen provider, several options are shown. Each will show map tiles in a different appearance. Please choose a map type from the list. |
API Key (required) |
This field is only visible if you selected a provider that requires an API key. Please obtain your personal key and paste it here. For more information on how to get an API key, please see the More section below. Please enter an alphanumeric string. |

For more information on how to speed up the web interface, please see More section below. |
IP Address for Web Server |
PRTG is running a web server in order to provide access via the web and Windows interface. Please specify which IP address this web server will run on. Note: Later, you can log into PRTG by simply pointing your browser to the specified IP address. Choose between:
Note: If you run PRTG on localhost, please do not use the DNS name http://localhost to log in to the web server, as this may considerably slow down PRTG's web interface. Please use your local IP address or http://127.0.0.1 instead.
Note: Regardless of the selected setting above, one port in the range from 8080 to 8180 has to be available on the specified IP address so PRTG can create reports. The report engine will try to connect to the core server on one of these ports. Note: If PRTG does not find a network card on startup it will switch the IP setting to Localhost. This setting will remain, even if a network card is available later on. If you disabled or removed the network card on the machine running the PRTG core server, please re-check this setting. Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |
TCP Port for Web Server |
PRTG is running a web server in order to provide the web and Windows interface. Please specify on which port this web server will run. Choose between:
Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |
Web Server Port |
This setting is only visible if the expert configuration is selected above. Enter the desired TCP port number you want the PRTG web server to run on. Please enter an integer value. Note: If you use a secure connection and port 80 is free, PRTG will reserve it as well. When users try to connect on port 80 via HTTP, they will then be redirected to the custom port via HTTPS. You can change this behavior using a registry setting. Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |
Web Server Security |
This setting is only visible if the expert configuration is selected above. Specify if you want to use an SSL encryption. Choose between:
Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |
Currently Active IP Address/Port Combination(s) |
Shows all currently active combinations of IP addresses and ports on which the PRTG server listens for web requests. This setting is shown for your information only and cannot be changed here. Note: PRTG internally uses port 8085 for report generation. |
Graph Settings: Select for how many days historic data remains accessible |
|
---|---|
PRTG shows several graphs in the objects' detail pages in the web interface. These are kept in RAM memory for fast display without causing extra CPU load or disk usage. The longer the time frames and the shorter the intervals are, the more memory will be used for this. You can adapt the details for all four graphs. This setting will also change the caption of the objects' tabs in the web interface and Enterprise Console. Note: If you change this setting, PRTG needs to restart the core server. Because of this, all users of PRTG's web interface, of the Enterprise Console, or of Smartphone Apps will be disconnected. After clicking on the Save button, a popup will appear which asks you to confirm the required core server restart. Click on OK to trigger the restart and follow the instructions on the screen. |

Live Graph |
The live graph is available for sensors only. For the live graph, no fixed time span is given, but you can define how many values will be displayed. The actual time span covered by the live graph depends on the scanning interval set for the sensor you're viewing and is calculated automatically. By default, 120 Values is set, which results in a graph covering a time span of two hours, if a scanning interval of 60 seconds is set for the sensor. Other scanning intervals will result in graphs covering different time spans. Choose between:
|
Graph 1 |
By default, this is the 2 days graph in the web interface. You can change it to more or less detail by choosing a time span and a monitoring interval average associated with it. Monitoring results will be averaged regardless of the actual scanning interval set for the sensors. Choose between:
|
Graph 2 |
By default, this is the 30 days graph in the 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 between:
|
Graph 3 |
By default, this is the 365 days graph in the 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 between:
