If you run PRTG in a cluster, you also see a cluster-related element. It shows the name of the cluster node that you are logged in to and displays whether this is a master node or a failover node. Click the bar to show the cluster status. On a failover node, you can review all data, but PRTG does not save changes in the settings. To change the settings, log in to the master node.

Navigation

To navigate the PRTG web interface, the following options are available:

  • The main menu bar 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).
  • The clickable breadcrumbs show the path to a selected object in the object hierarchy.
  • Click an object to see its details. In the page heading of the page header bar, you always see the name of the object that you have selected.
  • Use the page tabs to switch between various subpages.
  • Right-click objects to open their context menu.
  • Hover over objects to display tool tips. Hover longer to open a quick-access window (hover popup).
  • Drill down into the object hierarchy of probes, groups, devices, and sensors in the device tree. To do so, click a subobject of the displayed object (for example, click a sensor on a device's Overview tab).

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

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

The tree map view displays all devices of your entire installation as tiles that are sorted into a square and that are arranged according to the groups they belong to. Each device dynamically changes color to reflect the overall status of the sensors on the device.

Tree Map View

Tree Map View

The following aspects apply to both the sunburst view and the tree map view:

Colors

A device or group can have different colors, depending on the states of the sensors that are on the device or in the group. The sensor states are ranked according to their priority, for example, the Down status has a higher priority than the Warning status, which has a higher priority than the Up status.

A tile shows the color of the sensor status with the highest priority. For example, if a device has sensors in the Up (green), Paused (blue), and Warning (yellow) status, the corresponding tile shows a yellow color to indicate that at least one sensor on this device is in the Warning status. If a single sensor changes to the Down status, the corresponding tile turns red.

In the following table, you can find all sensor states sorted by the highest priority to the lowest priority:

Default Objects in the Device Tree

By default, PRTG creates a probe device on the local probe (PRTG on premises) or on the hosted probe (PRTG hosted by Paessler). The probe device represents the probe system. PRTG automatically monitors the system health of the PRTG core server and each probe to discover overload that might distort monitoring results. To monitor the status of the probe system, PRTG automatically creates the following sensors:

In a cluster, PRTG also creates a cluster probe device with a Cluster Health sensor that monitors the cluster's system health.

Priority and Favorites

You can mark a device or sensor as a favorite. To do so, click i_flag_transparent to the right of the respective object in the device tree. The flag turns dark gray. To remove an object from your favorites, click i_flag_black. The flag turns transparent again.
