PRTG Manual: SSH Remote Ping Sensor
The SSH Remote Ping sensor remotely monitors the connectivity between a system running Linux/macOS X and another device, using Internet Control Message Protocol (ICMP) echo requests ("ping") and Secure Shell (SSH).
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.
- Dutch: SSH Remote Ping
- French: Ping distant (SSH)
- German: SSH Remote Ping
- Japanese: SSH リモート Ping 実行
- Portuguese: Ping remoto (SSH)
- Russian: Удаленный пинг по SSH
- Simplified Chinese: SSH 远程 Ping
- Spanish: Ping remoto (SSH)
- This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.
- This sensor requires credentials for Linux/Solaris/macOS (SSH/WBEM) systems in the settings of the parent device.
- This sensor does not support all Linux/Unix and macOS distributions.
- This sensor only supports IPv4.

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 |
---|---|
Target |
Enter the Domain Name System (DNS) name or IP address of the target device the ping is sent to. The sensor remotely connects to the parent device it is created on via SSH, then performs a ping request from this remote device to the target device or server. Enter a string. |
Packet Size (Bytes) |
Enter the packet size for the ping in bytes. You can enter any value between 1 and 10000. Enter an integer.
|
Packet Count |
Enter the number of packets that the sensor sends with each scanning interval. |
Custom Parameter |
Optionally, enter additional parameters that the sensor adds at the end of the ping command. Enter a string or leave the field empty.
|
Setting |
Description |
---|---|
Connection Timeout (Sec.) |
Define a timeout in seconds for the connection. This is the time that the sensor waits to establish a connection to the host. Keep this value as low as possible. Enter an integer. The maximum timeout value is 900 seconds (15 minutes).
|
Shell Timeout (Sec.) |
Define a timeout in seconds for the shell response. This is the time in seconds the sensor waits for the shell to return a response after it has sent its specific command (for example, cat /proc/loadavg). The maximum value is 300 seconds (5 minutes). Enter an integer.
|
SSH Port |
Define which port this sensor uses for the SSH connection:
|
Use Port Number |
This setting is only visible if you select Enter custom port number above. Enter the port number (between 1 and 65535) that this sensor uses for the SSH connection. Enter an integer. |
SSH Engine |
Select the SSH engine that you want to use to access data with this SSH sensor:
|
Result Handling |
Define what PRTG does with the sensor result:
|
Setting |
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.
Channel |
Description |
---|---|
Avg. Response |
The average response time measured from the remote device |
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 |
Max Response |
The maximum response time measured from the remote device |
Min Response |
The minimum response time measured from the remote device |
Packet Loss |
The packet loss (%)
