PRTG Manual: SNMP SonicWall VPN Traffic Sensor

Connection

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.

Sensor Name

Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

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 ().

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.

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

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
