Page Element report

The graphs in this report show time intervals, attempts, hits, and successes.

• The interval depends on the Statistics sample interval value that you set for the schedule.
• An attempt means that a request was sent.
• A hit means that the server received the request and returned any response.
• A success means that the response code verification point passed for that request. If the request has no verification point, a success means that the server received a request and returned a response where the status code was in the 200 or 300 category, or returned an expected response in the 400 or 500 category.
• The response time is the time between the first request character sent and the last response character received. The response time does not include HTTP requests that time out or requests that return a status code in the range of 4XX (client errors) - 5XX (server errors) or requests that timed out.Response times for HTTP requests that time out or that return an unexpected status code (the recorded and played back codes do not match) in the range of 4XX (client errors) to 5XX (server errors) are discarded from the reported values.

Overall page

• The average response time for all page elements in the entire run
• The standard deviation of the average response time. The standard deviation tells you how tightly the data is grouped about the mean. For example, System A and System B both have an average response time of 12 ms. However, this does not mean that the response times are similar. System A might have response times of 11, 12, 13, and 12 ms. System B might have response times of 1, 20, 25, and 2. Although the mean time is the same, the standard deviation of System B is greater and the response time is more varied.
• The average number of page elements attempted for the entire run
• The total page element attempts for the entire run

Response vs. Time Summary page

• The average response time for that page element during the entire run
• The standard deviation of the average response time. The standard deviation tells you how tightly the data is grouped about the mean. For example, System A and System B both have an average response time of 12 ms. However, this does not mean that the response times are similar. System A might have response times of 11, 12, 13, and 12 ms. System B might have response times of 1, 20, 25, and 2. Although the mean time is the same, the standard deviation of System B is greater and the response time is more varied.
• The attempts per second during the most recent sample interval
• The number of attempts during the most recent sample interval

Page Element Throughput page

• The Page Element Hit Rate graph shows the combined attempt rate and hit rate for all page elements during the last recorded interval. The table after the graph lists one number: the average hit rate for all pages in the run. When a schedule includes staged loads, colored time-range markers at the top of the graph delineate the stages.
• The User Load graph shows active users compared to users that have completed testing. The table after the graph lists the number of active users, the number of users that have completed testing, and the total user count for the entire run.

Server Health Detail page

• The number of attempts
• The number of hits
• The number of successes
• The percent of successes (matches the information in the bar chart)
• The number of attempts per second

Caching Details page

• The Caching Activity graph shows the total number of page element cache attempts, page element cache hits, page element cache misses for the run. These values correspond to responses from the server indicating whether the content has been modified. Additionally, the bar chart shows the total number of page elements in cache skipped for the run. That value indicates the cache hits that were still fresh in the local cache, where communication with the server was not necessary.
• The Page Element Cache Hit Ratios graph shows the percentage of cache attempts that indicate server-confirmed success and client-confirmed success for the run. Server-confirmed cache hits occur when the server returns a 304 response code. Client-confirmed cache hits occur when the content is still fresh in the local cache and no communication with the server is required.
• The summary table under the charts lists the the total number of page elements found fresh in the cache for the run. This value indicates the cache hits that were still fresh in the local cache, where communication with the server was not necessary. The table also lists the number of attempts, the total number of page element cache attempts sent to the server, and the total number of page element cache hits confirmed by the server for the run. Additionally, the table lists the percentage of cache attempts that indicate server-confirmed success and client-confirmed success for the run.
