Solution 2157378.1 : Diameter Signaling Router (DSR) : Value For "RxConnRecvBufAvg" Counter Shows "n/a" Value

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.0 and later
Information in this document applies to any platform.

Symptoms

Counter "RxConnRecvBufAvg" in "Connection Performance" Report for Connections shows values as " n/a".

Cause

System is working as per design.

Solution

RxConnRecvBufAvg: The average number of bytes in the SCTP/TCP receive buffer. The bytes in the receive buffer are those received from the peer but not yet read by the peer state machine.

When we configure any new Connection, It will be in Disabled state and hence it will not show in measurement report. Once we Enable the Connection it will start showing in measurement report with n/a value for RxConnRecvBufAvg.

Initially when connection is enabled, then "RxConnRecvBufAvg" will be “n/a”.

We will be having traffic running on it, but traffic is getting processed normally without waiting in buffer, then also RxConnRecvBufAvg will be “n/a”.

Once we have high traffic or the Application is taking long time to process the incoming traffic, so in such case few messages will wait in Rx buffer, those will be pegged in "RxConnRecvBufAvg" and will have some values like <10>,<100>,<1000> .. depending on messages pegged.

Again when traffic rate becomes normal and no messages are going to be in buffer, then RxConnRecvBufAvg value will be display “0”.

When you will disabled the connection, then RxConnRecvBufAvg will be “n/a” again.
