| Processes | 1 | process handle count high |
| Storage device IO | 1 | disk unresponsive |
| Storage IO | 2 | disk latency degraded, disk saturated |
| Windows platform event channels | 4 | gpu resources saturated, os boot duration high, os shutdown duration high, ram commit exhausted |
| Windows System event log | 7 | failover cluster csv unavailable, failover cluster node removed, failover cluster quorum loss, failover cluster resource failed, failover cluster resource hang, failover cluster resource host crash, failover cluster service down |
