This monitor tracks the status of the HPC Diagnostics Service. When this service is stopped, diagnostic tests cannot be run on the HPC cluster.
This error can be caused by any of the following:
The HPC Diagnostics Service encountered an error and had to stop running.
The HPC Diagnostics Service is disabled.
Group Policy does not allow this service to start.
To troubleshoot and fix this problem:
Restart the HPC Diagnostics Service on the target head node. In a cluster configured for high availability of the head node, the service runs only on the active head node. Use Failover Cluster Manager to restart the service in a high availability environment.
Start Event Viewer on the target node and check for any system events from the Service Control Manager or application events from the HPC Diagnostics Service. Resolve any errors that are reported by these events.
If the service still cannot be restarted, contact the domain administrator to make sure that this service is not disabled by the domain Group Policy.
If the preceding steps do not resolve the problem, uninstall and reinstall Microsoft HPC Pack on the node.
