Alert Attachment File Share Availability Monitor

Microsoft.SystemCenter.AlertAttachment.AlertAttachmentFileShare.AvailabilityState.Monitor (UnitMonitor)

This monitor verifies connectivity to the alert attachment file share from the management servers.

Knowledge Base article:

Summary

The alert attachment file share processing workflows log events to indicate connectivity and security issues. This monitor sets the health state of the file share instance based on these events.

The monitor automatically resets the health state to Healthy with each successful file share operation. Use the monitor health history to analyze past connectivity issues.

The alert attachment share processing workflow permanently unloads when connectivity or security issues occur. You need to manually restart Health Service to restart workflows.
