Average Distribution

Select ANALYZE > Graphs > Statistics > Average Distribution to view the average server response time distribution.

The graph's horizontal axis shows the response time, and the vertical axis shows the percentage of the samples with a particular response time.

This graph is useful because ... you can identify overloaded servers that need hardware upgrades. If a high percentage of requests to a particular server have long response times, it is typically because the server's hardware is not able to cope with the amount of work that the server has to do.
  • Servers: Select which servers and server groups to base the graph on, server groups are enclosed in <>. Only server groups and monitored servers are listed, see Server Lists for details about monitored ports.

    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 graph on, port groups are enclosed in <>. Only port groups and monitored ports are listed, see Port Lists for details about monitored ports.
  • Agents: Select which group of computers that the graph should be based on. Super groups, that is groups of groups, are enclosed in <>.
  • 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 graph's horizontal axis. If you leave the fields empty, the range will automatically reflect the minimum and maximum values found in the data.
  • Connect samples: The graph values are default drawn as single dots. Select this box to connect the dots by a thin line.

 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.
