Adaptive Server Anywhere provides a set of statistics that can be used to
monitor database performance. These are accessible from Sybase Central,
and client applications can access the statistics as functions. In addition,
these statistics are made available by the server to the Windows NT
performance monitor.
This section describes how to access performance and related statistics from
client applications, how to monitor database performance using Sybase
Central, and how to monitor database performance using the Windows NT
performance monitor.
The Windows NT performance monitor is an application for viewing the
behavior of objects such as processors, memory, and applications. Adaptive
Server Anywhere provides many statistics for the performance monitor to
display.
