PRTG Manual: Show Dependencies
The Dependencies feature gives an overview of the dependencies that are configured for the objects in your setup.
To see an object's dependencies, select Devices | Dependencies from the main menu bar.
Dependencies Graph View
Tab |
Description |
|---|---|
Overview |
Shows the dependencies graph. This is a visualization of device, group, and sensor dependencies.
|
Selected Dependencies |
Shows a table list of manually set dependencies (see the Dependency setting in section Schedules, Dependencies, and Maintenance Window in any object's settings). |
Master Dependencies |
Shows a table list of master dependencies. |
The Overview tab shows the device tree in the dependencies graph view. The lines in the dependencies graph symbolize dependencies between the monitoring objects in the device tree. Additionally, PRTG uses different line colors for the dependencies. You can also view the dependencies in different table lists on the Selected Dependencies tab or the Master Dependencies tab.
To show the dependencies graph, you need to access the PRTG web interface as an administrator.
The following actions are available:
- Enable the Show or Hide option to show or hide master dependencies. Hide is enabled by default to only show parent dependencies, selected dependencies, and broken dependencies.
For technical reasons, the Show and Hide radio buttons are not available in Internet Explorer. Use Google Chrome 75 or Mozilla Firefox 67 instead. - Click
or 
in the upper-left corner to zoom in or out of the dependencies graph. - Click probe and group nodes to show the respective dependencies.
- Click device or sensor nodes to open the corresponding Overview tab.
- Click
or 
to expand or collapse probe and group nodes. - The numbers in parentheses indicate how many child nodes of an object are shown.
The line's colors show the kind and source of a dependency. This represents the Dependency Type as defined in the Schedules, Dependencies, and Maintenance Window settings of a probe, group, device, or sensor.
You can also find the legend for the line colors in the graph header bar.
Color |
Description |
|---|---|
Gray |
Gray lines show a dependency by inheritance (Use parent (default) setting). The source of the dependency is the parent object on the left end of the line, for example, Root is the parent of Local Probe.  Gray Line for Parent Dependency |
Green |
Green lines show a master dependency for a device (Master sensor for parent setting). The sensor that is set as the master points to the dependent device with a green arrow head at the line's end. The arrow head from the dependent device to its master sensor is pink.  Green Line for Master Dependency |
Pink |
Pink lines show a dependency that you set manually (Select a sensor setting). The source of the dependency points to the dependant with a pink arrow at the line's end.  Pink Line for Selected Dependency |
Red |
Red lines indicate broken dependencies, for example, if the master sensor is not available.  Red Line for Broken Dependency |
