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. |
Control | 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. |
