PRTG Manual: Traceroute Hop Count v2 Sensor

Sensor message

The sensor message shows all IP addresses in the current route of hops. If a hop does not respond, the sensor message shows an asterisk (*) instead of an IP address.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a medium performance impact.

Timeout (Sec.)

Enter a timeout for individual ping requests in seconds. The default value is 5. The maximum value is 300.

Pings per Hop

Enter the number of ping requests the sensor sends per hop on the route. The default value is 3. The maximum value is 10.

Time to Live (Hops)

Define the time to live (TTL) for each ping. You can limit the number of network hops that the request can traverse before it is dropped. The default TTL is 64.

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.

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.
• Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

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.

Hops

The number of hops

This channel is the primary channel by default.
