PRTG Manual: Active Directory Replication Errors Sensor

The Active Directory Replication Errors sensor checks a Windows domain controller (DC) for replication errors.

For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
Performance impact	This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.
Member of Windows domain	This sensor only works if the probe system is part of the domain whose Active Directory you want to monitor.
.NET 4.7.2 or later	This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node. If the sensor shows the error PE087, additionally install .NET 3.5 on the probe system. If the framework is missing, you cannot create this sensor. For more information, see the Knowledge Base: Which .NET version does PRTG require?
Windows Server	We recommend Windows Server 2016 on the probe system for best performance of this sensor.
Parent device	This sensor requires that the parent device is a DC.
Credentials	This sensor requires credentials for Windows systems. Otherwise, the sensor cannot correctly connect. We recommend that you use Windows domain credentials. If you use local credentials, make sure that the same Windows user accounts (with the same user name and password) exist on both the probe system and the target system.
IPv6	This sensor supports IPv6.
Lookups	This sensor uses lookups to determine the status values of one or more channels.
Hosted probe	You cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

Sensor Settings

Setting	Description
Replication Neighbor	The replication neighbor whose replication connection this sensor monitors.
Naming Context	Select the Active Directory naming context that you want to monitor: Configuration (default): Includes information about partitions, sites, services, or the Active Directory schema. Schema: Includes the information by which objects, classes, and attributes that are used in the Active Directory are defined. DomainDnsZones: Includes information about the domain controllers that are in the domain. Domain: Includes domain information that is replicated to this domain's domain controllers, for example information about computers or users. The probe system must be part of the domain whose naming context you want to monitor. ForestDnsZones: Includes information about domain controllers in the forest. You cannot change this value after sensor creation.

Setting

Description

Replication Neighbor

The replication neighbor whose replication connection this sensor monitors.

Naming Context

Select the Active Directory naming context that you want to monitor:

Configuration (default): Includes information about partitions, sites, services, or the Active Directory schema.
Schema: Includes the information by which objects, classes, and attributes that are used in the Active Directory are defined.
DomainDnsZones: Includes information about the domain controllers that are in the domain.
Domain: Includes domain information that is replicated to this domain's domain controllers, for example information about computers or users.
The probe system must be part of the domain whose naming context you want to monitor.
ForestDnsZones: Includes information about domain controllers in the forest.

You cannot change this value after sensor creation.

Debug Options

Setting	Description
Result Handling	Define what PRTG does with the sensor result: Discard result (default): Do not store the sensor result. Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval. In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Setting

Description

Result Handling

Define what PRTG does with the sensor result:

Discard result (default): Do not store the sensor result.
Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Sensor Display

Setting	Description
Primary Channel	Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
Graph Type	Define how this sensor shows different channels: 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 generates a graph that visualizes the different components of your total traffic. You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
Stack Unit	This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit 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.

Setting

Description

Primary Channel

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

You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

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 generates a graph that visualizes the different components of your total traffic.
You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit 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 these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.

For more information, see section Inheritance of Settings.

Channel List

Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Setting	Description
Consecutive Sync Failures	The number of consecutive synchronization failures
Downtime	In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status.
Is Deleted Source	If the source is deleted Up status: No Down status: Yes
Last Sync Attempt	The time of the last synchronization attempt
Last Sync Result	The result of the last synchronization This channel is the primary channel by default.
Last Sync Success	The time of the last synchronization success
Modified Consecutive Sync Failures	The number of modified, consecutive synchronization failures
Pending Replication Operations	The number of pending replication operations
Scheduled Sync Disabled	If the scheduled synchronization is disabled Up status: No Down status: Yes
