  • The minimum scanning interval for this sensor is 30 minutes.
  • This sensor only supports OneDrive Personal, it does not work with OneDrive Business.
  • For details about OAuth2 authentication, see section Authentication Using OAuth2.

Add Sensor

The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the setting fields that are required for creating the sensor. Therefore, you will not see all setting fields in this dialog. You can change (nearly) all settings in the sensor's Settings tab later.

icon-toolsPRTG requires OAuth2 authorization before you can actually add this sensor. Provide the requested credentials in the appearing window.

The following settings in the Add Sensor dialog differ in comparison to the sensor's Settings tab.

Microsoft Credentials

This sensor uses OAuth2 authentication to get access to your Microsoft account.

icon-book-arrowsFor details about this authentication approach, see section Authentication Using OAuth2.


Click the Get Access Code button to connect this sensor to your Microsoft account using OAuth2. This is necessary to allow the sensor to query data from OneDrive. A new browser window appears.

Follow the steps in the window and confirm the permission for PRTG to connect to your OneDrive account. OneDrive forwards you to an empty page after completing the authorization process. Copy the complete URL of this empty page and paste it into the OAuth Code field below.

OAuth Code

Paste the complete URL of the empty page to which OneDrive forwards you. The empty page appears after completing the authorization process for PRTG at your OneDrive account. Click OK to define the sensor settings.

icon-i-round-redIt is mandatory to connect this sensor to your OneDrive account to create this sensor. Complete the OAuth approach first to get the OAuth code.

Sensor Settings

On the details page of a sensor, click the Settings tab to change its settings.

icon-i-roundUsually, a sensor connects to the IP Address or DNS Name of the parent device on which you created the sensor. See the Device Settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings. See below for details on available settings.

Basic Sensor Settings

Sensor Name

Enter a meaningful name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

Parent Tags

Shows Tags that this sensor inherits from its parent device, group, and probe. This setting is shown for your information only and cannot be changed here.


Enter one or more Tags, separated by spaces or commas. You can use tags to group sensors and use tag–filtered views later on. Tags are not case sensitive. We recommend that you use the default value.

There are default tags that are automatically predefined in a sensor's settings when you add a sensor. See section Default Tags below.

You can add additional tags to the sensor if you like. Other tags are automatically inherited from objects further up in the device tree. These are visible above as Parent Tags.

icon-i-roundIt is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).


Select a priority for the sensor. This setting determines where the sensor is placed in sensor lists. A sensor with a top priority is at the top of a list. Choose from one star (low priority) to five stars (top priority).

Default Tags

msonedrivesensor, cloudstorage

Microsoft Credentials

OAuth Code

Shows the authorization code that the sensor uses to get access to your OneDrive account. Once you have created a sensor, you cannot change this value. It is shown for reference purposes only. If you need to change this value, please add the sensor anew.

Sensor Display

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.

icon-i-roundYou can set a different primary channel later by clicking the pin symbol of a channel on the sensor's Overview tab.

Graph Type

Define how different channels will be shown for this sensor.

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This will generate a graph that visualizes the different components of your total traffic.
    icon-i-roundThis option cannot be used in combination with manual Vertical Axis Scaling (available in the Sensor Channel Settings settings).

Stack Unit

This field is only visible if you enable Stack channels on top of each other above. Select a unit from the list. All channels with this unit will be stacked 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.

Inherited Settings

By default, all of the following settings are inherited from objects that are higher in the hierarchy and should be changed there if necessary. Often, best practice is to change them centrally in the Root group's settings. For more information, see section Inheritance of Settings. To change a setting for this object only, disable inheritance by clicking the button next to inherit from under the corresponding setting name. You will then see the options described below.

Scanning Interval

Click inherited_settings_button to interrupt the inheritance. See section Inheritance of Settings for more information.

Scanning Interval

Select a scanning interval (seconds, minutes, or hours). The scanning interval determines the amount of time that the sensor waits between two scans. You can change the available intervals in the system administration on PRTG on premises installations.

If a Sensor Query Fails

Define the number of scanning intervals that the sensor has time to reach and check a device again in case a sensor query fails. Depending on the option that you select, the sensor can try to reach and check a device again several times before the sensor will show a Down status. This can avoid false alarms if the monitored device only has temporary issues. For previous scanning intervals with failed requests, the sensor will show a Warning status. Choose from:

  • Set sensor to down immediately: Set the sensor to a Down status immediately after the first failed request.
  • Set sensor to warning for 1 interval, then set to down (recommended): Set the sensor to a Warning status after the first failed request. If the following request also fails, the sensor will show an error.
  • Set sensor to warning for 2 intervals, then set to down: Set the sensor to a Down status only after three consecutively failed requests.
  • Set sensor to warning for 3 intervals, then set to down: Set the sensor to a Down status only after four consecutively failed requests.
  • Set sensor to warning for 4 intervals, then set to down: Set the sensor to a Down status only after five consecutively failed requests.
  • Set sensor to warning for 5 intervals, then set to down: Set the sensor to a Down status only after six consecutively failed requests.

icon-i-roundSensors that monitor via Windows Management Instrumentation (WMI) always wait at least one scanning interval before they show a Down status. It is not possible to immediately set a WMI sensor to a Down status, so the first option will not apply to these sensors. All other options can apply.

icon-i-roundIf you define error limits for a sensor's channels, the sensor will immediately show a Down status. No "wait" option will apply.

icon-i-roundIf a channel uses lookup values, the sensor will immediately show a Down status. No "wait" options will apply.

icon-i-roundThis sensor has a fixed minimum scanning interval for performance reasons. You cannot run the sensor in shorter intervals than this minimum interval. Consequently, shorter scanning intervals as defined in System Administration—Monitoring are not available for this sensor.

Schedules, Dependencies, and Maintenance Window

icon-i-roundYou cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects will always be active. However, you can define additional settings here. They will be active at the same time as the parent objects' settings.


Select a schedule from the list. Schedules can be used to monitor for a certain time span (days or hours) every week.

icon-book-arrowsYou can create schedules, edit schedules, or pause monitoring for a specific time span. For more information, see section Account Settings—Schedules.

icon-i-roundSchedules are generally inherited. New schedules will be added to existing schedules, so all schedules are active at the same time.

Maintenance Window

Specify if you want to set up a one-time maintenance window. During a maintenance window, the current sensor and all child objects will not be monitored. They will be in a Paused status instead. Choose between:

  • Not set (monitor continuously): No maintenance window will be set and monitoring will always be active.
  • Set up a one-time maintenance window: Pause monitoring within a maintenance window. You can define a time span for a monitoring pause below and change it even for a currently running maintenance window.

icon-i-roundTo terminate a current maintenance window before the defined end date, change the time entry in Maintenance Ends to a date in the past.

Maintenance Begins

This field is only visible if you enable Set up a one-time maintenance window above. Use the date time picker to enter the start date and time of the maintenance window.

Maintenance Ends

This field is only visible if you enable Set up a one-time maintenance window above. Use the date time picker to enter the start date and time of the maintenance window.

Dependency Type

Define a dependency type. You can use dependencies to pause monitoring for an object depending on the status of another object. You can choose from:

  • Use parent: Use the dependency type of the parent device.
  • Select a sensor: Use the dependency type of the parent device. Additionally, pause the current sensor if another specific sensor is in a Down status or in a Paused status caused by another dependency. Select below.
  • Master sensor for parent: Make this sensor the master object for its parent device. The sensor will influence the behavior of its parent device: If the sensor is in a Down status, the device will be paused. For example, it is a good idea to make a Ping sensor the master object for its parent device to pause monitoring for all other sensors on the device in case the device cannot even be pinged. Additionally, the sensor will be paused if the parent group is paused by another dependency.

icon-i-roundTo test your dependencies, select Simulate Error Status from the context menu of an object that other objects depend on. A few seconds later, all dependent objects will be paused. You can check all dependencies in your PRTG installation by selecting Devices | Dependencies from the main menu bar.


This field is only visible if you enable Select a sensor above. Click the Search button and use the object selector to select a sensor on which the current sensor will depend.

Dependency Delay (Sec.)

This field is only visible if you enable Select a sensor above. Define a time span in seconds for dependency delay.

After the master sensor for this dependency comes back to an Up status, monitoring of the dependent objects will be additionally delayed by the defined time span. This can help avoid false alarms, for example, after a server restart, by giving systems more time for all services to start up. Enter an integer value.

icon-i-round-redThis setting is not available if you set this sensor to Use parent or to be the Master sensor for parent. In this case, define delays in the parent Device Settings or in its parent Group Settings.

Access Rights

Click inherited_settings_button to interrupt the inheritance. See section Inheritance of Settings for more information.

User Group Access

Define the user groups that will have access to the selected object. A table with user groups and types of access rights is shown. It contains all user groups from your setup. For each user group, you can choose from the following access rights:

  • Inherited: Use the access rights settings of the parent object.
  • None: Users in this group cannot see or edit the object. The object neither shows up in lists nor in the device tree. Exception: If a child object is visible to the user, the object is visible in the device tree but it cannot be accessed.
  • Read: Users in this group can see the object and review its monitoring results.
  • Write: Users in this group can see the object, review its monitoring results, and edit its settings. They cannot edit access rights settings.
  • Full: Users in this group can see the object, review its monitoring results, edit its settings, and edit access rights settings.

You can create new user groups in the System Administration—User Groups settings. To automatically set all objects further down in the hierarchy to inherit this object's access rights, set a check mark for the Revert children's access rights to inherited option.

icon-book-arrowsFor more details on access rights, see section User Access Rights.

Channel Unit Configuration

Click inherited_settings_button to interrupt the inheritance. See section Inheritance of Settings for more information.

Channel Unit Types

For each type of sensor channel, define the unit in which data is displayed. If defined on probe, group, or device level, these settings can be inherited to all sensors underneath. You can set units for the following channel types (if available):

  • Bandwidth
  • Memory
  • Disk
  • File
  • Custom

icon-i-roundCustom channel types can be set on sensor level only.

Authentication Using OAuth2

icon-sheet-ok-blueThis sensor uses the OAuth2 security protocol to access the account from which you want to retrieve and monitor data. OAuth2 enables you to grant access to the target account without sharing your password with PRTG. The authorization approach of PRTG using OAuth2 works as follows.

  1. Authorization Request
    First, you have to request authorization for this sensor to access service resources from your account. For this purpose, you are asked to get an access code for this sensor in the Add Sensor dialog. Click the Get Access Code button to start the authorization process using OAuth2. A new browser window will open on the authorization server of the target service.
  2. Verifying Identity
    This new window contains a login form for your account that you want to monitor. Log in to your account using your credentials for this service to authenticate your identity. This is a common login to your account on the target server so PRTG will not see your password. The service will forward you to the authorization page and asks you to permit PRTG to access the data in your account.
    icon-i-roundIf you are already logged in to the service with a user account,
    you do not have to enter credentials in this step and get directly to the access permission page.
  3. Authorizing PRTG
    Permit PRTG to access information on your account. Note that this permission holds only for this specific sensor, not for other sensors of this type or PRTG as a whole. For each sensor of this type you add, you have to confirm the access permission anew. You can change the account permissions at any time in your account at the target service.
  4. Getting Authorization Code
    Permitting PRTG to access your account data forwards you to a page where the service provides an authorization code. Copy this code and switch back to the Add Sensor dialog in PRTG.
    icon-i-round-redThe code is only valid for a short period of time and expires after a few minutes.
    You can use a particular code only once.
  5. Providing Authorization Code
    Paste the authorization code into the OAuth Code field and complete the Add Sensor dialog. You do not have to go through further configuration steps manually. The sensor will accomplish the following steps automatically.
  6. Requesting Access Token
    After receiving the authorization code, PRTG will request an access token from the API of the target service. For this purpose, PRTG transmits the authorization code together with several authentication details. The API checks if the authorization is valid and returns the access token to PRTG. Access tokens are specific for one account and one application (here: PRTG). The authorization process to read data from your account is now complete.
  7. Retrieving Data
    The sensor transmits the access token with each sensor scan in the defined scanning interval to authenticate with your account. It is not necessary to use the original account credentials anew. The used tokens will refresh automatically from time to time.
