Collecting statistics for a specific time period

The syntax for admin stats is:

admin { stats | statistics } [, sysmon | "all"
        | module_name [, inbound | outbound ] [, display_name] ]
        [, server[, database ]      | instance_id ]
        [, display |, save [, obs_interval ] ]
        [, sample_period]

admin stats lets you specify:

Noteadmin stats also supports the cancel option. This stops the currently running command.

By default, Replication Server does not report counters that show 0 (zero) observations for the sample period. You can change that behavior by setting the stats_show_zero_counter configuration on using configure replication server. See the Replication Server Reference Manual for complete syntax and usage information.
