5 Managing OpenFlow alerts and
troubleshooting service flows
SDNM is used to manage OpenFlow alerts and troubleshoot SDN service flows.
Managing OpenFlow alerts
When a controller is added to SDNM, SDNM registers an alert listener with the controller so that the
controller can send the generated OpenFlow alerts to SDNM.
SDNM enables is used to view, query, acknowledge, recover, and delete the following OpenFlow alerts:
• OpenFlow alerts generated by controllers.
• OpenFlow alerts generated by SDNM.
Accessing the alert list page
1. Click the Service tab.
2. From the navigation tree, select VAN SDN Manager > OF Monitor > Alerts.
The alert list displays all alerts in SDNM.
Alert list contents
{ Level—Severity level of the alert. Options are:
− Critical
− Major
− Minor
− Warning
− Info
{ Recovery Status—Whether or not the alert has been recovered:
− If the alert has not been recovered, this field displays Unrecovered. Click the Unrecovered
link to manually recover the alert.
− If the alert has been manually recovered by an operator, this field displays the operator
name.
− If the alert has been automatically recovered or was sent to SDNM to clear a previous alert,
this field displays "$SYSTEM."
{ Acknowledgement Status—Whether or not the alert has been acknowledged:
− If the alert has not been acknowledged, this field displays Unacknowledged. Click the
Unacknowledged link to acknowledge the alert.
− If the alert has been acknowledged by an operator, this field displays the operator name.
{ Alert Source—IP address of a controller. The alert might be sent by the controller or generated
by SDNM for the controller. Click the alert source to view the controller details. For more
information, see "Viewing SDN controller information."
