The graph tool is the principal onperf interface.
Use the graph tool to display any set of database server metrics that
the onperf data collector obtains from shared memory.
The Graph-Tool
window shows a
diagram of a graph tool that displays a graph of metrics for ISAM
calls. Figure 1: Graph-Tool
window
You cannot bring up a graph-tool window from a query-tree tool,
a status tool, or one of the activity tools.
