PRTG Device Tree

PRTG Device Tree

From top to bottom, the device tree screen has several areas that are covered in further detail in this section. For a general overview of the device tree, consider the table below.

Page area name

Description

Global Header Area

This area contains the main menu at the very top, the global status bar, the path to the currently selected object, and a quick search box.

Page Header Bar

This area contains the page heading with the name of the current object, several tabs with settings, monitoring data of the current object, and quick action buttons.

Page Content

This area contains information about the current object and all other objects underneath in the tree hierarchy, the object's status bar, a quick search box, and the QR code that links to the current URL.

Viewing options

These buttons are part of the page content. Here you can adjust how your device tree is displayed.

Page Footer

Shows information about the current version of PRTG, the logged in PRTG user account, and the current time (depending on the timezone settings for the currently logged in user).

A timer counts down how much time remains until the next automatic page refresh. You can pause the refresh timer with the pause icon and resume with the play icon. If you open another page while the refresh timer is paused, the timer resumes automatically, starting with the defined Auto Refresh Interval (Sec.) that you can configure in your account settings.

icon-i-round-redLong table lists that are set to display 1000 items at a time are excluded from the automatic refresh to ensure system performance.

Page Footer Icons

With these icons, you have quick access to the PRTG Auto-Update page if a new version is available and to the contact support form. There is also a link to context-sensitive help.

When running PRTG in a cluster, you also see a cluster-related element. It shows the name of the node that you are logged in to and displays whether this is a master or a failover node. Click the bar to show the Cluster Status. In a failover node, you can review all data, but changes in the settings are not saved. In order to change settings, log in to the master node of your cluster.

Click an object to see its details page. In the page heading of the page header bar, you always see the name of the object that you have currently selected.

When navigating the PRTG web interface, the following paths are available:

  • The main menu provides access to all important aspects of the software.
  • The quick search is often the fastest way to find a specific object (for example, a sensor or a device).
  • Using the page tabs, you can switch between various subpages.
  • Right-clicking objects opens a context menu.
  • When pausing over objects, the tool tip appears, and after further hovering, a quick-access window (Hover Popup) opens.
  • You can drill down into the object hierarchy of probes, groups, devices, and sensors in the object tree merely by clicking a subobject of the currently displayed object (for example, a sensor on the device page).

These navigation paths offer complete access to the functionality of PRTG.

In the following, we describe the different areas of the web interface.

Search Box, Logout

Via the icons in the top-right corner, you can start a search or log out.

To search for a monitoring object, enter a name, parts of a name, an IP address, a DNS name, or a tag in the search box on the right and confirm with enter. PRTG performs a string search in your entire monitoring setup, including groups, devices, sensors, libraries, maps, reports, tickets, and object comments.

A page with the items that are related to the search term opens—even displaying online help articles.

5

Breadcrumbs

Below the main menu, PRTG shows a path that retraces the steps back to the welcome screen (or your defined starting page). Use it to quickly jump back to where you came from. Breadcrumbs can also help you to orient yourself if you get lost. If you click the down arrow on a breadcrumb item, a dropdown menu opens that shows all objects on the same level. You can either search for an object or select one directly. For example, you can directly access all other sensors on a device, other devices within a group, and another group on the same probe. Other probes in your root group are also available.

Page Header Bar

The page header bar below the global header area consists of a number of elements shown in the table below.

Switch Device Tree View—Extended Views

There are two additional options to the simple tree views that enable you to display the status of all sensors of your entire installation in a single overview. Click one of the icons to change the view:

Sunburst View
The sunburst view displays your entire installation as a circle diagram. The groups are represented as inner circles, and all devices contained within a group are shown as 'cake slices' attached to the outside of a circle element.

The sunburst is interactive:

  • You can click elements to open the details view of your monitoring objects.
  • You can zoom in and out by using the plus + and minus buttons or your mouse wheel.
  • You can change the position of the sunburst on the Overview tab with drag-and-drop.

Tree Map View
The tree map view displays all devices of your entire installation as tiles sorted into a square and arranged according to the groups they belong to. Each device dynamically changes color to reflect the overall status of the sensors on the device. You can also adjust the square size: either depending on a device's priority, or depending on the number of sensors on a device, or depending on both. To do this, click the Size by: Sensors and/or Priority setting in the page header bar (see the mark in the screenshot below).

PRTG Tree Map View

For both views:

  • Colors
    A device (or group) element can have different colors, depending on the states of the sensors running on this device or group (see Sensor States). A higher status is regarded as more important and takes precedence, that is, it is prioritized higher. For example, if a device currently has sensors in the states Up (green), Paused (blue), and Warning (yellow), according to device prioritization, this tile is then yellow, indicating that at least one sensor on this device is in Warning status. If a single sensor changes to Down status, the corresponding device tile turns red. Correspondingly, the PRTG states (for both views) are shown here in order of their prioritization:

Default Objects in the Device Tree

By default, a Probe Device is created in the device tree on the local probe or hosted probe. It represents the probe system running with your PRTG installation. PRTG automatically monitors the system health of the core server and each probe to discover overload that may distort monitoring results. To monitor the system status of the probe computer, PRTG automatically creates a few sensors:

In a cluster installation, PRTG also creates a Cluster Probe Device with a Cluster Health sensor that monitors the cluster's system health.

We recommend that you keep these sensors, but they are all removable.

Priority and Favorites

You can tag a device or sensor as favorite by clicking the flag displayed to the right of it (see screenshot below). To untag devices, proceed in the same way.

One-Click Favorites in the Device Tree
