22054 - Route List Degraded

Alarm Group:

DIAM

Description:

The Route List's Operational Status has changed to degraded because the capacity of the Route List's active route group has dropped below the Route List's configured minimum capacity. There are two potential causes:

1. One or more of the Route List's peers become Unavailable. A peer becomes unavailable when all of its transport connections become unavailable. If a transport connection is configured for Initiate mode, the network element periodically attempts to recover the connection if its admin state is enabled. If the transport connection is configured for responder-only mode, the peer is responsible for re-establishing the transport connection.
2. The Route Groups within the Route List may not have been configured with sufficient capacity to meet the Route List's configured minimum capacity.

Severity:

Major

Instance:

<RouteListName> (of the Route List which is degraded)

HA Score:

Normal

Auto Clear Seconds:

0 (zero)

OID:

Cause:

There are no available Route Groups, and the Operational Status of one or more Route Groups within the Route List is degraded.

Diagnostic Information:

A Route List's operational status is always set to the operational status of the Route Group within the Route List that is designated as the Active Route Group.

DRL determines which Route Group within a Route List is designated the Active Route Group for that Route List as follows:

• If the operational status of one or more Route Groups within the Route List is Available, then the Active Route Group for the Route List is the Available Route Group with the highest priority
• If there are no Available Route Groups, and the operational status of one or more Route Groups within the Route List is Degraded, the Active Route Group is the Degraded Route Group with the highest Current Capacity. If two or more degraded Route Groups exist with equal Current Capacity, then the Active Route Group is the one with the highest Priority
• If all Route Groups within the route list are Unavailable, then the Route List is Unavailable and there is no Active Route Group

Recovery:

1. Verify Route List status and configured minimum capacity from Diameter > Maintenance > Route Lists.
2. Verify IP network connectivity exists between the MP server and the peers.
3. Check the event history logs for additional DIAM events or alarms from this MP server.
4. Verify the peers in the Route List are not under maintenance.
5. If the problem persists, it is recommended to contact My Oracle Support.
