Monitor Performance Using Counters

Replication Server has several hundred different counters that can monitor performance at various points and areas in the replication process.

By default, counters are not active until you choose to activate them—with the exception of a few counters that are always active.

To monitor performance using the RepAgent counters, see Replication Server Administration Guide Volume 1 > Manage RepAgent and Support Adaptive Server > Use Counters to Monitor RepAgent Performance.

  You can view current counter values and other performance information at any time using several commands.
