<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: PRTG Administrator on Core Server System
With the PRTG Administrator program you can define various system-oriented settings that affect your PRTG installation, as well as restart services and view log information. You can change many of these settings also via the system administration in the PRTG web interface.
Note: To get familiar with the different components of PRTG, we recommend you to read the Architecture section.
Note: All settings you define here are only valid for the local installation running on the computer you open the program on. In order to change settings for another installation, for example, another cluster node installation, please log in to this computer and open the program there.
Note: This section describes the available settings in the PRTG Administrator when you open the tool on the PRTG core server system (core resp. web server and local probe related). If you open this program on a remote probe machine, only probe related settings are available.
From the PRTG Network Monitor group in Windows start menu, please select PRTG Administrator to open the application. You can choose from these options in different tabs:
- Web Server
- Core Server
- Cluster
- Administrator
- License
- Probe Settings for Core Connection
- Probe Settings for Monitoring
- Service Start/Stop
- Logs and Infos
When you close the program with the Ok button after changing settings, you are asked to restart the core server Windows service and/or probe service in order to save the settings. Please confirm by clicking the OK button. Otherwise the changes are ignored.
PRTG Administrator: Restart Services
Edit IPs, ports, access methods, and language for the Ajax and Mobile Web GUI web interfaces.
Note: You can change all settings which are on the Web Server tab also via the PRTG web interface in the User Interface settings.
PRTG Administrator: Web Server
Web Server |
|
---|---|
Select TCP Port for PRTG's 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:
|
Expert Configuration: SSL Encryption |
This setting is only visible if the expert configuration is selected above. Specify if you want to use an SSL encryption. Choose between:
|
Expert Configuration: 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. |
Select IP Address for PRTG's 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. |
Select System Language |
Choose the system language from the drop down list. 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 Administrator Tool. |
Define settings for the core server.

Follow these instructions to create or join a cluster, or to change its settings:
Create a PRTG Cluster...
- Start creating a cluster by clicking this button. The current PRTG core server will then be the Master Node of your cluster.
- After you click this button, please confirm converting this installation into a master node by clicking on the Yes button.
Converting an Installation into a Cluster Master Node
- A new dialog box will appear.
PRTG Administrator: Creating a Cluster Master
- Enter a Cluster Port. This is the port on which the internal communication between the different cluster nodes is sent. Make sure connections between cluster nodes are possible on the selected port.
- Enter or paste a Cluster Access Key. This is a unique access key. All nodes in a cluster have to be configured with the same cluster access key in order to join the cluster. Connection attempts with the wrong access key will be rejected.
- We recommend using the default value.
- Save the Cluster Access Key so you have it at hand when configuring your Failover Node(s).
- After confirming your settings you will be asked to restart Windows services. Please do so in order for your changes to take effect.
Join a PRTG Cluster...
- Add this installation to an existing cluster which already has a Master Node, by clicking this button. The current PRTG core server will then be a Failover Node in the cluster.
- Note: This button is also available if you are currently running your PRTG installation in Cluster Mode: Master Node. This option will then change your master node to a failover node!
- After you click this button, confirm converting this installation into a failover node by clicking on the Yes button.
Converting an Installation into a Cluster Failover Node
- A dialog box will appear.
PRTG Server Administrator
- Enter the cluster's Master IP address/DNS name. It must be reachable from the machine running the failover node.
- Enter the other settings as defined in your Master Node's settings. Please make sure you use the same settings on all nodes in your cluster.
- Enter a Cluster Port. This is the port on which the internal communication between the different cluster nodes is sent. Make sure connections between cluster nodes are possible on the selected port.
- Enter or paste a Cluster Access Key. This is a unique access key. All nodes in a cluster have to be configured with the same cluster access key in order to join the cluster. Connection attempts with the wrong access key will be rejected.
- After confirming your settings you will be asked to restart Windows services. Please do so in order for your changes to take effect.
Change PRTG Cluster Settings...
PRTG Server Administrator
- If you are running your PRTG installation in cluster mode, you can change the settings here. A new window will appear.
- Enter a Cluster Port. This is the port on which the internal communication between the different cluster nodes is sent. Make sure connections between cluster nodes are possible on the selected port.
- Enter or paste a Cluster Access Key. This is a unique access key. All nodes in a cluster have to be configured with the same cluster access key in order to join the cluster. Connection attempts with the wrong access key will be rejected.
- Please make sure you use the same settings on all nodes in your cluster.
- After confirming your settings you will be asked to restart Windows services. Please do so in order for your changes to take effect.
Revert to Standalone...
- If you are currently running your PRTG installation in cluster mode, you can change it to Standalone mode. If you do so, this node will no longer be part of a cluster.
- After confirming your settings you will be asked to restart Windows services. Please do so in order for your changes to take effect.
Master Heartbeat
This section is only visible if you are running your PRTG installation in cluster mode. The current master can execute an external executable file on a regular basis. We call this a "heartbeat".
You can use this, for example, to report the IP address of the current master node to a dynamic DNS provider, so a DNS name is always redirected to the current PRTG master node in case the original master node fails and a failover node (running at a different IP address) takes over the master role.
Choose between:
- No heartbeat: Do not execute a file on a regular basis.
- Run the following external executable file every 5 minutes: Click on the ... button to choose a file you want to execute. This can be, for example, a command line tool, or a batch file. It will be executed on the current master node only, with a fixed interval of five minutes. The interval cannot be changed.
Note: Please make sure the selected file is available under the same (local) path on all failover nodes. In case one of your failover nodes becomes current master, the heartbeat can only be executed reliably if the respective executable file exists on all of your failover nodes.
Change PRTG System Administrator specific settings.
Note: You can change these settings also in the account settings of the PRTG System Administrator user in the PRTG web interface.
