Using BTS Measurements

Revised: February 18, 2010, OL-16000-07

Introduction

This chapter describes BTS traffic measurements and tells you how to use them. BTS does the following:

•Collects statistics in 5-, 15-, 30-, or 60-minute intervals.

•Collects TG statistics at 100 second intervals.

•Clears measurements after each interval without loss of ongoing counts.

•Saves 48 hours of statistical data in 5-, 15-, 30-, or 60-minute increments in persistent store.

•Displays of summary report of past 48-hour period.

•Provides 0n-demand report queries keyed by collection interval.

•Issues events.

There are many measurement types, but they all have a similar format. Only titles and measurement labels differ. Each header tells you where the data is from and whether it is normal or suspect.

Access BTS measurements using the following:

•Command-line interface (CLI), which runs over a telnet or secure shell (SSH) session.

•Comma-separated value (CSV) or Extensible Markup Language (XML) format via FTP or SFTP interface.

•SNMP MIB (version v2c).

Measurements without data for the given interval do not appear in reports.

Using Measurements

When working with measurements watch for the following:

•rapid buildup of counts—Sometimes that means congestion or processing failures.

•disparity in measurement pairs that are normally equal—The greater the difference between the two, the more likely there is a problem. For example, successful incoming messages should be nearly equal to incoming messages:
