TR can produce several reports based on a single statistic from your Logs. These statistics can tell you how many hits your web site has gotten, whether your servers holding up well or not under the demands your web sites placing on it, and so on.
The numeric reports include:
- Transfers - The number of files your visitors requested from your server whether they could be sent successfully or not.
- Hits - The number of files your server could successfully send your visitors.
- Errors - File requests your server couldnt meet due to an error by your server or by the visitors browser. Often, errors are caused by broken links at your web site.
- Violations - File requests your server couldnt meet because a visitor lacked an acceptable password. Watch for Violation Clusters to appear during full moons, space/time continuum disruptions or civil unrest.
- Bytes Sent - The amount of info your server is providing your web sites visitors.
- Transfer Time - The length of time it took your server to send your web sites visitors all the stuff they asked for.
- Thruput - A measure that tells you how fast or slow your server is able to send out info. Displayed in bytes per second, the higher this number, the faster your server is at fulfilling its visitors requests.
- Methods - The method of a file request. The Get method means a visitor requested info from your server. Put is when the visitor sends info to your server. Head is like Get except that only the http header info is sent, such as when the requested file was retrieved from a browsers cache.
For TR to be able to create each of these reports, your log must contain the corresponding statistic used by each report. Your log entries should also include a date and time. See Appendix F for a information about the log format you are using and how its fields correspond to these statistics. (The Thruput report requires that your log contains both Bytes Sent and Transfer Time.)
In the above reports the stats are broken down by:
- Agent (such as Explorer or Navigator) also requires Agent field
- Object (such as Image, Text, etc.) also requires URL field
- Operating System (like Unix, Mac OSand Windows) also requires Agent field
The last three subtotal the stats by the categories youve set up for Agents, Objects and oss. See the Creating Report Categories section for how to create your own categories.
A Day-by-Day Stats report summarizes these statistics for each date.
