Measurement Group: Server M3UA Performance

Measurement Type: Average

Description: The average SCTP Aggregate Association Writer Queue utilization (0-100%) measured during the collection interval.

Collection Interval: 30 min

Peg Condition: The average of all SCTP Aggregate Association Writer Queue utilization samples taken during the collection interval.

Measurement Scope: NE, Server

Recovery:

An IP network or STP/SG problem may exist preventing SCTP from transmitting messages into the network on multiple Associations at the same pace that messages are being received from the network.
One or more SCTP Association Writer threads may be experiencing a problem preventing it from processing events from its event queue. Examine the alarm log from the GUI main menu under Alarms & Events>View Active.
If one or more MPs in a server site have failed, the traffic will be distributed among the remaining MPs in the server site. You can monitor MP server status from Status & Manage>Server.
The misconfiguration of STP routing may result in too much traffic being distributed to the MP. You can monitor the ingress traffic rate of each MP from Status & Manage>KPIs. Each MP in the server site should be receiving approximately the same ingress transaction per second.
There may be an insufficient number of MPs configured to handle the network traffic load. You can monitor the ingress traffic rate of each MP from Status & Manage>KPIs. If all MPs are in a congestion state, then the offered load to the server site is exceeding its capacity.
If the problem persists, contact My Oracle Support (MOS).
