Viewing HTTP Reports
The HTTP report displays the hit rates for HTTP optimization for the time period specified.
For details about operating report controls, see Overview.
The HTTP report graph displays these statistics that summarize HTTP data activity.
Data Series
Description
Request Rate
Select to display the rate of HTTP objects, URLs, and object prefetch requests.
Object Prefetch Table Hit Rate
Select to display the hit rate of stored object prefetches per second. The SteelHead stores object prefetches from HTTP GET requests for cascading style sheets, static images, and Java scripts in the Object Prefetch Table.
URL Learning Hit Rate
Select to display the hit rate of found base requests and follow-on requests per second. The SteelHead learns associations between a base request and a follow-on request. Instead of saving each object transaction, the SteelHead saves only the request URL of object transactions in a Knowledge Base and then generates related transactions from the list.
Parse and Prefetch Hit Rate
Select to display the hit rate of found and prefetched embedded objects per second. The SteelHead determines that objects are going to be requested for a given web page and prefetches them so that they are readily available when the client makes its requests.
The navigator shadows the object prefetch table hit rate series.
What This Report Tells You
The HTTP Stats report answers this question:
•  How many HTTP objects were obtained and transmitted over the WAN?
About Report Graphs
Use the mouse to hover over a specific data point to see the y values and exact time stamp were in relation to peaks.
About Report Data
The SCC system reports on performance for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled.
For detailed information about data grouping, see Data Grouping.
To view the HTTP report

Description
Time Interval
Select a report time interval of 1 hour (1h), 1 day (1d), 1 week (1w), 30 days (30d), yesterday, last week, or last month.
Time intervals that do not apply to a particular report are dimmed.
For a custom time interval, enter the start time and end time using the format YYYY/MM/DD HH:MM:SS.
Because the system aggregates data on the hour, request hourly time intervals. For example, setting a time interval to 08:30:00 to 09:30:00 from 2 days ago does not create a data display, whereas setting a time interval to 08:00:00 to 09:00:00 from 2 days ago will display data.
When you request a custom time interval to view data beyond the aggregated granularity, the data is not visible because the system is no longer storing the data. For example, the following custom time intervals do not return data because the system automatically aggregates data older than 7 days into 2-hour data points:
•  Setting a 1-hour time period that occurred 2 weeks ago.
•  Setting a 75-minute time period that occurred more than 1 week ago.
You can quickly see the newest data and see data points as they are added to the chart dynamically. To display the newest data, click Show newest data.

Select the group from the drop-down list.
