Managing MDI health issues
MDI has several health alerts that will be triggered if certain configuration options are no longer configured properly, were forgotten in the initial setup, or if communication and performance problems occur. For example, if MDI sensors identify no domain controller traffic is being received, if the sensor isn’t updating automatically, or if there are errors with event analysis. The list of detectable health issues is dynamic and changes as the product life cycle changes, so you may also receive notifications about end-of-life versions of Windows Server if a sensor runs on them.
These alerts, depending on severity, should be handled as soon as possible as they might impair MDI’s ability to successfully monitor the environment.
The health alerts in MDI can be accessed from the Security Portal available at security.microsoft.com | Settings | Identities | General and the Health issues part, as shown in the following screenshot:
