PRTG Manual: Ping Sensor
The Ping sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability.
The default number of pings per scanning interval is 5.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a very low performance impact. |
Multi-platform probe |
You can add this sensor to a multi-platform probe. |
Knowledge Base |
|
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- pingsensor
For more information about basic sensor settings, see section Sensor Settings.
Setting |
Description |
---|---|
Timeout (Sec.) |
Enter a timeout in seconds for the ping. If the reply takes longer than this value, PRTG cancels the request and shows an error message. Enter an integer. The maximum timeout value is 300 seconds (5 minutes). |
Packet Size (Bytes) |
Enter the packet size for the ping in bytes. You can enter any value between 1 and 10000. Enter an integer.
|
Ping Method |
Define the kind of ping check that the sensor performs with each scanning interval:
|
Ping Count |
This setting is only visible if you select Send multiple ping requests (default) above. Enter the number of pings that the sensor sends in a row in one scanning interval. Enter an integer. The default value is 5. |
Ping Delay (ms) |
This setting is only visible if you select Send multiple ping requests (default) above. Enter the time in milliseconds (ms) that the sensor waits between two ping requests. Enter an integer. The default value is 5.
|
Acknowledge Automatically |
Define if you want to automatically acknowledge the Down status of the sensor:
|
Setting |
Description |
---|---|
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.
|
Graph Type |
Define how this sensor shows different channels:
|
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. |
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Description |
---|---|
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 |
Maximum |
The maximum ping time when using more than one ping per interval |
Minimum |
The minimum ping time when using more than one ping per interval |
Packet Loss |
The packet loss when using more than one ping per interval (%) |
Ping Time |
The ping time
