Calculating Statistics

The monitor phase is responsible for collecting gateway data and calculating statistics. There are two types of counter statistics:

• Snapshot statistics Each snapshot statistic is derived from one measurement recorded at one particular moment in time, such as the number of messages in the out-queue or the number of threads in use. Folder snapshot statistics are generated using the folder snapshot functions provided by STATS.LIB.
• Period statistics Each period statistic is based on measurements recorded over a period of time, such as messages received per hour or the maximum number of messages in the in-queue during a four-hour period. They are generated from snapshot statistic derivations, using the jump window functions provided by STATS.LIB.
