Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Credentials |
This sensor requires credentials for Linux/Solaris/macOS (SSH/WBEM) systems in the settings of the parent device. |
Distributions |
|
Performance impact |
This sensor has a medium performance impact. |
IPv4 |
This sensor only supports IPv4. |
Knowledge Base |
|
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- memorysensor
- sshmeminfosensor
For more information about basic sensor settings, see section Sensor Settings.
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 Inheritance |
Define which port this sensor uses for the SSH connection:
|
Custom SSH Port |
This setting is only visible if you select Do not inherit port (enter a custom SSH port) 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, 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.
