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.

Description |
---|---|
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.
|
Parent Tags |
The tags that the sensor inherits from its parent device, parent group, and parent probe.
|
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.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
|
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 ( |
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 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 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:
|

Description |
---|---|
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.
|
Graph Type |
Define how different channels are shown for this sensor:
|
Stack Unit |
This setting is only visible if you select Stack channels on top of each other above. 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. |
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.
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.
For more information, see section Root Group Settings, section Access Rights.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

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 |

Minimum |
The maximum ping time when using more than one ping per interval |
Packet Loss |
