Health service data is not up to date alert

Overview

The agents on the on-premises machines that Microsoft Entra Connect Health monitors periodically upload data to the Microsoft Entra Connect Health Service. If the service does not receive data from an agent, the information the portal presents will be stale. To highlight the issue, the service will raise the Health service data is not up to date alert. This alert is generated when the service has not received complete data in the past two hours.

• The Warning status alert fires if the Health Service has received only partial data types sent from the server in the past two hours. The warning status alert does not trigger email notifications to configured recipients.
• The Error status alert fires if the Health Service has not received any data types from the server in the past two hours. The error status alert triggers email notifications to configured recipients.

The service gets the data from agents that are running on the on-premises machines, depending on the service type. The following table lists the agents that run on the machine, what they do, and the data types that the service generates. In some cases, there are multiple services involved in the process, so any of them could be the culprit.

Understanding the alert

The Alert Details blade shows when the alert occurred and was last detected. A background process that runs every two hours generates and re-evaluates the alert. In the following example, the initial alert occurred on 03/10 at 9:59 AM. The alert still existed on 03/12 at 10:00 AM when the alert was evaluated again. The blade also details the time the Health Service last received a particular data type.

The following table maps service types to corresponding required data types:

Service type	Agent (Windows Service name)	Purpose	Data type generated
Microsoft Entra Connect (Sync)	Microsoft Entra Connect Health Sync Insights Service	Collect Microsoft Entra Connect-specific information (connectors, synchronization rules, etc.)	- AadSyncService-SynchronizationRules - AadSyncService-Connectors - AadSyncService-GlobalConfigurations - AadSyncService-RunProfileResults - AadSyncService-ServiceConfigurations - AadSyncService-ServiceStatus
	Microsoft Entra Connect Health Sync Monitoring Service	Collect Microsoft Entra Connect-specific perf counters, ETW traces, files	Performance counter
AD DS	Microsoft Entra Connect Health AD DS Insights Service	Perform synthetic tests, collect topology information, replication metadata	- Adds-TopologyInfo-Json - Common-TestData-Json (creates the test results)
	Microsoft Entra Connect Health AD DS Monitoring Service	Collect ADDS-specific perf counters, ETW traces, files	- Performance counter - Common-TestData-Json (uploads the test results)
AD FS	Microsoft Entra Connect Health Agent	Perform synthetic tests	TestResult (creates the test results)
	Microsoft Entra Connect Health Agent	Collect ADFS usage metrics	Adfs-UsageMetrics
	Microsoft Entra Connect Health Agent	Collect ADFS-specific perf counters, ETW traces, files	TestResult (uploads the test results)

Troubleshooting steps

The steps required to diagnose the issue is given below. The first is a set of basic checks that are common to all Service Types.

Important

This alert follows Connect Health data retention policy

• Make sure the latest versions of the agents are installed. View release history.

• Make sure that Microsoft Entra Connect Health Agents services are running on the machine. For example, Connect Health for AD FS should have two services.

• Make sure to go over and meet the requirements section.

• Use test connectivity tool to discover connectivity issues.

• If you have an HTTP Proxy, follow these configuration steps.

Next steps

If any of the above steps identified an issue, fix it and wait for the alert to resolve. The alert background process runs every 2 hours, so it will take up to 2 hours to resolve the alert.
