Disabling RDR Aggregation

Disabling RDR Aggregation
In large deployments, if each traffic processor sends its own records separately to the CM, the number
of RDRs reaching the CM becomes enormous. Therefore, the Cisco SCE platform aggregates certain
RDRs, thus reducing the load on the CM without affecting the usability of the information provided. In
essence, the control processor receives records from all traffic processors, but it only sends one record
for each reporting period, containing the aggregated data of all CPUs together.
The RDR aggregation feature is relevant only to global records. More specifically, only periodic records
are aggregated, because other records relate to events like a single transaction or flow, and cannot be
aggregated across processors – if they are aggregated, they loose the required granularity.
Currently the following RDRs are aggregated:
•
•
•
You can disable RDR aggregation for either a specific RDR type, or for all aggregated RDRs.
From the SCE(config if)# prompt, type:
Command
no periodic-records aggregate-by-cpu [all |
LUR | PUR | VLUR]
periodic-records aggregate-by-cpu [all | LUR |
PUR | VLUR]
To display the current RDR aggregation configuration, use the following command:
