onperf utility metrics

When you use the onperf utility, you can view various metric classes.

The following sections describe these metric classes. Each section indicates the scope levels available and describes the metrics within each class.

Database server performance depends on many factors, including the operating-system configuration, the database server configuration, and the workload. It is difficult to describe relationships between onperf metrics and specific performance characteristics.

The approach taken here is to describe each metric without speculating on what specific performance problems it might indicate. Through experimentation, you can determine which metrics best monitor performance for a specific database server instance.
