Adding New Sensors using the Add Sensor Wizard
Adding new sensors in PRTG Traffic Grapher is easy. Merely click on Click here to add you first sensor: This will show the Add Sensor Wizard:
The Add Sensor Wizard will guide you through the setup of new sensors for monitoring with PRTG Traffic Grapher.
After having read the information on the title screen, press Next to continue on to the Data Acquisition Type Selection screen.
Here you can select which type of sensor you would like to monitor from the choices provided:
· SNMP
· Packet Sniffing
· NetFlow Collector
All three types are explained in-depth later in this manual.
For this sample, we will create an SNMP sensor since this is the most common option.
Click Next after having made your selection.
Here, you can select the type of SNMP sensor you would like to monitor. The options are:
· Standard Traffic Sensor
· SNMP Helper Sensor
· Choose from an OID/MIB Library
· Custom SNMP Sensor
For this tutorial we create a Standard Traffic Sensor (you need to have a compatible device in your network). Select the appropriate type of sensor from the list and click Next to continue.
This will launch the Device Selection screen.
Here, you will need to enter a Device Name/Alias for the sensor you would like to set up. Next, you will need to enter the IP Address/DNS Name of the device you would like to monitor.
You may also need to update the SNMP community string, as well as the SNMP port. Usually it should be fine to keep the defaults (“public” for the SNMP Community String and “161” for the SNMP port). Contact your network admin if you are not sure.
Click Next to continue. Now PRTG Traffic Grapher tries to contact the device for the first time.
If the connection fails you will get an error message. In this case, please follow the instructions on the screen and see the next section in this manual for more information on troubleshooting!
If the connection works you will be shown the Port Selection:
Here, you will be provided with a list of selectable ports and devices. Check one or more entries you would like PRTG Traffic Grapher to monitor, select whether you want to monitor Bandwidth, Unicast-Packets, Non-Unicast-Packets, or Errors and then click Next in order to set up the Additional Settings.
Choose a group from the sensor list that you want to add the new sensor(s) to. Optionally you can Create a New Subgroup.
Choose a group name that will help you to keep your sensors organized (e.g. “Firewall” or “LAN”). Also select the desired scanning interval in seconds. In most cases 30 seconds should be fine.
Note: Small intervals create higher network load but will give you a more “current view” of the measured data. Longer intervals will cause smaller network load but the measured data will be more “averaged”.
Once you have selected your preferences, click on Finish and PRTG Traffic Grapher will begin monitoring your newly defined sensor(s) in a few seconds.
