To view descriptive and status information about Replication Server counters, use the rs_helpcounter stored procedure. See “Viewing information about the counters”.
Each counter has a descriptive name and a display name that you use to identify the counter when you enter RCL commands and when you view displayed information.
Different kinds of counters provide different types of information. Although not all counters can be divided into discrete categories, when Replication Server displays counter information it uses these categories:
Observers – collect the number of occurrences of an event over a time period. For example, observers might collect the number of times a message is read from a queue. Replication Server reports the number of occurrences and the number of occurrences per second.
Monitors – collect measurements at a given time or times. For example, monitors might collect the number of operations per transaction. Replication Server reports the number of observations, the last value collected, the maximum value, and the average value.
Counters – collect a variety of measurements. Counters that measure duration are in this group as are counters that collect total numbers of bytes. For this category, Replication Server can report number of observations, total value, last value, maximum value, an average, and rate per second.
