Replication Server 15.0 provides a new, simpler interface for monitoring the counters that provide performance information. By default, all counters are inactive until you turn them on using either:
The admin stats (admin statistics) command, which activates counters for a specific time period, or
The Replication Server configuration parameter stats_sampling, which is a toggle that activates or deactivates counters.
Using admin stats, you can specify which counter statistics to report, whether to display those statistics on the screen or save them to the RSSD, and how many seconds to collect the statistics. admin stats lets you specify statistics for:
Individual counters
Individual modules
The sysmon counters, which are a set of counters Sybase has identified as those most valuable for monitoring performance
All counters
Viewing statistics on screen provides a point-in-time benchmark. Saving statistics to the RSSD lets you accumulate data, so you can see changes in statistics over time, and perform averages and other calculated values. You can specify a sampling period and the number of observations during that sampling period.
When you turn on counter activity using stats_sampling, the counters stay active until you turn them off.
New admin stats options are:
admin stats, backlog – reports the current backlog in the inbound and outbound stable queues.
admin stats, { tps | cps | bps } – reports throughput in transactions per second, commands per second, or bytes per second.
admin stats, status – reports configuration information for counters.
