PRTG Manual: Ping v2 Sensor
The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability.
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 |
---|---|

Setting |
Description |
---|---|
Inverted Error Status |
Select if you want the sensor to show the Down status if the target is reachable:
To change this behavior after sensor creation, open the channel settings of channel Status and change the Lookup. Select prtg.standardlookups.paessler.icmp.reachability_state if you want the sensor to show the Down status if the target is not reachable. Select prtg.standardlookups.paessler.icmp.reachability_state_reversed if you want the sensor to show the Down status if the target is reachable. If you select Enable, Status is the primary channel. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- icmp
- ping
- 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. We recommend that you use the default value. |
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. Increase the value if the target device drops ping packets because of denial of service (DoS) suspicion. |
Time to Live (Hops) |
Define the time to live (TTL) for the request. You can limit the number of network hops that the request can traverse before it is dropped. The default value is 64. |
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. 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:
|
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. |
Setting |
Description |
---|---|
Result Handling |
Define what PRTG does with the sensor result:
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. |
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.
Channel |
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 Response Time |
The maximum ping time when using more than one ping per interval |
Minimum Response Time |
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 (%) |
Response Time |
The ping time This channel is the primary channel by default. |
Status |
The target status
This is the primary channel if you enable Inverted Error Status. |
