Response Times Versus Load

Response Time Versus Load (ANALYZE > Graphs > Statistics > Response Time Versus Load) is a scatter plot that shows server response time plotted against the number of requests per second.

This graph is useful because ... it helps you uncover otherwise hidden scaling problems. If response times increase to a non-acceptable level when the number of requests per second increases, it's very likely the result of an overloaded server getting more requests than it can handle.

Servers: Select which servers and server groups to base the plot on, server groups are enclosed in <>. Only server groups and monitored servers are listed, see Server Lists for details about monitored servers.
Select multiple servers and server groups by pressing the CTRL key while selecting the servers.
Ports: Select which port or port group to base the plot on, port groups are enclosed in <>. Only port groups and monitored ports are listed, see Port Lists for details about monitored ports.
Agents: Select the group of computers that the plot should be based on.
Interval: Select the period of time that the graph should cover. If the predefined intervals don't suit you, select Custom to specify your own interval.
Y-axis Min and Max: Specify the range that you require for the graph's vertical axis. If you leave the fields empty, the range will automatically reflect the minimum and maximum values found in the data.
X-axis Min and Max: Specify the range that you require for the horizontal axis. If you leave the fields empty, the range will automatically reflect the minimum and maximum values found in the data.
Large Markers: The values are plotted as small dots. Select this box to draw large markers instead.
Use large markers if you don't expect the graph to contain much data.

Is performance good or bad?

That depends on the type of work that you do in your organization, but you can often follow our rules of thumb.
