Response Time Histogram

The Response Time Histogram displays response times for selected servers.

To view the histogram, select ANALYZE > Graphs > Statistics > Histogram.

The histogram consists of 10 individual bars.

Each bar represents the percentage of replies within a given milliseconds interval.

This way you can very quickly find out if a particular server is potentially overloaded—like the blue one in the example image.

• Servers: Select which servers or server groups you want to base your histogram on. Server groups are enclosed in <>. You can only select server groups and monitored servers. See Server Lists for details about monitored servers.

  Select multiple servers and server groups by pressing the CTRL key while selecting the servers.

• Agents: Select the group of computers you want to base your histogram 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.
• Ports: Select which port or port group you want to base your histogram on. Port groups are enclosed in <>. You can only select port groups and monitored ports. See Port Lists for details about monitored ports.
