3.47 SyncRequest

Use this Knowledge Script to monitor the number of failed Active Directory replication synchronization requests from the target server. This script raises an event if the number of synchronization requests that fail per second exceeds the threshold you set.

This script gathers the following Windows performance counter values for use in data collection and threshold monitoring:

Performance Objects

Counters

NTDS

DirectoryServices

The following counters are used to determine the number of failed sync requests:

  • DRA Sync Requests Made

  • DRA Sync Requests Successful

The number of failed sync requests is calculated using the following formula:

DRA Sync Requests Made - DRA Sync Requests Successful

The number of failed sync requests for the current iteration is computed by subtracting the number of failed sync requests at the previous iteration. The percentage of failed synchronization requests since the past iteration is computed and used for threshold comparison.

3.47.3 Setting Parameter Values

Set the following parameters as needed:

Parameter

How to Set It

General Settings

Raise event if job fails

Event severity when job fails

Set the severity level, from 1 to 40, to indicate the importance of an event in which the SyncRequest job fails. The default is 35.

Monitor synchronization failure rate?

Event Notification

Raise event if sync failure rate exceeds threshold?

Select Yes to raise an event if the sync failure rate exceeds the threshold you set. The default is Yes.

Threshold -- Maximum sync failure rate

Specify the maximum percentage of synchronization requests that can have failed since the last script iteration before an event is raised. The default is 90%.

Event severity when sync failure rate exceeds threshold

Set the severity level, from 1 to 40, to indicate the importance of an event in which the sync failure rate exceeds the threshold. The default is 20.

Data Collection

Collect data for synchronization failures?

Select Yes to collect data for charts and reports. If enabled, data collection returns:

  • The synchronization failure rate

  • The total number of synchronization requests made

  • The number of successful synchronization requests

The default is unselected.
