Knowledge Base

• Knowledge Base: Why does PRTG write error messages into my SonicWall log?

Connection

Select the connections that you want to monitor. PRTG creates one sensor for each connection that you select.

Security Policy

The security policy of the connection that this sensor monitors.

Remote IP Address

The remote IP address of the connection that this sensor monitors.

Source IP Addresses

The source IP addresses of the connection that this sensor monitors.

Destination IP Addresses

The destination IP addresses of the connection that this sensor monitors.

Index

The index of the connection that this sensor monitors.

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.

You cannot change this value after sensor creation.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel 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 this sensor shows different channels:

• 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 select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit 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

Decrypted Transmissions

The decrypted transmissions

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

This channel is the primary channel by default.

Encrypted Transmissions

The encrypted transmissions

Fragmented Packets In

The number of incoming fragmented packets

Fragmented Packets Out

The number of outgoing fragmented packets
