Page Footer

Shows information about the version of PRTG, the logged in user account, and the time (depending on the time zone settings for the 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 and starts 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 auto-update settings if a new version is available and to the contact support form. There is also a link to context-sensitive help.

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 changes in the settings are not saved. In order to change the settings, log in to the master node.

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.

When you navigate 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).
  • Use the page tabs to switch between various subpages.
  • Right-click objects to open a context menu.
  • Hover over objects to display tool tips, and hover longer to open a quick-access window (hover popup).
  • Drill down into the object hierarchy of probes, groups, devices, and sensors in the object tree. To do so, click a subobject of the displayed object (for example, click a sensor on a device's Overview tab).

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

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

Extended Device Tree 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 with 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).

For both views:

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

Default Objects in the Device Tree

By default, PRTG creates a probe device on the local probe or hosted probe. It 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 a few sensors:

In a cluster, 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. To do so, click the flag to the right of it (see screenshot below). To untag devices, proceed in the same way.
