Meaning
The sum of inbound and outbound packet error rates exceeds the configured
threshold for 15 minutes. The default is one error per second per interface.
The alert identifies the interface using its nic label.
Impact
Packet errors may cause retransmissions, lower throughput, and intermittent connection failures.
Diagnosis
-
Inspect
windows:net_received_errors:rateandwindows:net_outbound_errors:rateseparately to identify the direction. -
Compare traffic and
windows:net_received_utilization:ratioandwindows:net_sent_utilization:ratiowith the normal baseline. These ratios use bandwidth in bytes per second and keep each direction separate. -
Inspect local adapter state and counters:
Get-NetAdapter Get-NetAdapterStatistics -
Inspect switch-port counters, cabling, link negotiation, NIC drivers, and System event logs. For virtual NICs, inspect the host and virtual switch.
Mitigation
Repair faulty links or switch ports and correct driver or adapter configuration problems. Apply driver and firmware fixes through the normal change process. Relieve congestion if it contributes. Verify errors stop increasing and affected application connections recover; cumulative counters do not need to return to zero for the rate alert to resolve.
