1 Alarm Description

This alarm is raised when the number of Rx session establishment answered with result code too busy exceeds its corresponding configured threshold value.

The alarm is associated to the rxAaasInitTooBusy measure and Load Regulation function.

The main attributes of the alarm are the following:

2 Procedure

2.1 Handle Alarm Policy Control, Number of AAAs Initial Sent Indicating Too Busy Reached

Prerequisites

Before starting this procedure, ensure that you have read the following documents:
- For information about Handling Alarms, refer to Handling Alarms.
- For information about Load Regulation function, refer to Overload Control.
Before starting this procedure, ensure that the following tools are available:
- Ericsson Command Line Interface (ECLI).
- loadRegulationManager. More information in Overload Control User Guide.
No conditions are required.

Steps

Check that the threshold (thresholdHigh and thresholdLow attributes of the object indicated by source alarm field before ":" character) is configured according to the needs. More information in Measurements.
Check values for CPULoad.Total and Mem.PercentUsed (see Measurements).
Check values for Load Regulation constraints. Modify constraint values if they are not correct. For details see Overload Control User Guide.
Consider to redimension the SAPC if Load Regulation constraints values are properly configured.
If the alarm does not cease, consult the next level of maintenance support. Further actions are outside the scope of this procedure.
