5 Statistics and Reports

Overview

Introduction

This chapter explains the statistics produced by the application, and the reports you can run on the statistics.

Statistics

Introduction

The SIGTRAN TCAP Interface logs an array of statistics counters for each socket. Statistics are kept for:

  • Errors
  • Packets sent and received (per packet type)

Statistics for all connections

This table describes the statistics which are kept for all connections:

Statistic Description
RX_total Total packets received.
TX_total Total packets sent.
RX_error Number of errors when attempting to read a packet from a connection.
TX_error Number of errors when attempting to write a packet to a connection.
RX_corrupt

Number of packets received that contain incorrect data. This may be:

  • Incorrectly formatted packets
  • Correctly formatted packet that is not valid for the current state of the connection
TX_congest Number of outbound packets dropped due to transmit buffers being full.
connection_failures Number of times an error has resulted in the connection being disconnected.

SUA connections

For each packet type (for example, CLDT) two statistics are kept with the:

  • RX_ prefix, for packets received (for example, RX_CLDT).
  • TX_ prefix, for packets sent (for example, TX_CLDT).

M3UA connections

For each packet type (for example: DATA) two statistics are kept with the:

  • RX_ prefix, for packets received (for example, RX_DATA).
  • TX_ prefix, for packets sent (for example, TX_DATA).

SCCP over M3UA connections

In addition to the M3UA statistics, for each SCCP packet type (for example: UDT) two statistics are kept with the:

  • RX_SCCP_ prefix, for packets received (for example, RX_SCCP_UDT).
  • TX_SCCP_ prefix, for packets sent (for example, TX_SCCP_UDT).

Note: A SCCP UDT packet contained in a M3UA DATA packet will be counted in both the relevant SCCP and M3UA counters.
