Recommended Actions The alert is cleared either when the total NRF Forwarding rate falls below the critical threshold.

Note: The threshold is configurable in the alert file. Reassess why the NRF is receiving additional traffic (for example, Mated site NRF is unavailable in georedundancy scenario). If this alert is unexpected, contact My Oracle Support.

Steps:

  1. Refer Grafana to determine which service is receiving high traffic.
  2. Refer NRF Forwarding section in Grafana to determine the increase in 4xx and 5xx error codes.
  3. Check NRF Forwarding logs on Kibana to determine the reason for the errors.
