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:
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.
