<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: SNMP SonicWall VPN Traffic Sensor
The SNMP SonicWall VPN Traffic sensor monitors the traffic of an Internet Protocol Security (IPsec) VPN on a SonicWall Network Security Appliance (NSA) via the Simple Network Management Protocol (SNMP).

Remarks
Add Sensor
The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.
The settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog.

Connections
|
Select the connections that you want to monitor. PRTG creates one sensor for each connection that you select.
Enable check boxes in front of the respective lines to select the items. Use the check box in the table header to select all items or to cancel the selection. In large tables, use the search function in the upper-right corner.
|
Identification Method
|
Define how you want to identify the connection that you want to monitor:
- Index: Every connection has a unique index. This is the safest method to identify your connection. If the connection is lost and reconnected, it receives a new index.
- Remote IP address: If the target of the VPN always has the same IP address, you can use this IP address to identify the connection.
- Security policy name: If you use a different security policy for every VPN, you can use its name to identify the connection.
- Remote IP address and security policy name: You can also combine both identification methods.
- Remote IP address, security policy name, and IP address ranges: If you use separate connections for specific IP address ranges, identify the connection by remote IP address, security policy name, and IP address ranges.
- IP address ranges: Use IP address ranges only to identify the connection.
The sensor always uses the first connection that it finds that matches all criteria.

Basic Sensor Settings
Click the Settings tab of a sensor to change its settings.
Basic Sensor Settings
|
|
Sensor Name
|
Enter a name to identify the sensor.
|
Parent Tags
|
Shows tags that the sensor inherits from its parent device, parent group, and parent probe.
This setting is for your information only. You cannot change it.
|
Tags
|
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).
For performance reasons, it can take some minutes until you can filter for new tags that you added.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- snmpsonicwallvpntrafficsensor
- traffic
|
Priority
|
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().
|
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.

Security Policy
|
Shows the security policy of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
|
Remote IP Address
|
Shows the remote IP address of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
|
Source IP Addresses
|
Shows the source IP addresses of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
|
Destination IP Addresses
|
Shows the destination IP addresses of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
|
Index
|
Shows the index of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
|
Identification Method
|
Shows the identification method of the connection that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Primary Channel
|
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.
You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
|
Graph Type
|
Define how different channels are shown for this sensor:
- Show channels independently (default): Show a graph for each channel.
- Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
|
Stack Unit
|
This setting is only visible if you enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.
|
Inherited Settings
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Scanning Interval
Scanning Interval
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
Schedules, Dependencies, and Maintenance Window
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.
Access Rights

For more information, see section Root Group Settings, section Access Rights.
Channel Unit Configuration
Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.
Channel Unit Configuration
For more information, see section Root Group Settings, section Channel Unit Configuration.
Channel List
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Decrypted Packets
|
The number of decrypted packets per second
|
Decrypted Transmissions
|
The decrypted transmissions in bytes per second
|
Downtime
|
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status in percent.
|
Encrypted Packets
|
The number of encrypted packets per second
This channel is the primary channel by default.
|
Encrypted Transmissions
|
The encrypted transmissions in bytes per second
|
Fragmented Packets In
|
The number of incoming fragmented packets per second
|
Fragmented Packets Out
|
The number of outgoing fragmented packets per second
