Oracle Enterprise Manager can be used to manage Apache HTTP Server. You can use the All Metrics page for an Apache HTTP Server target to view the metrics that have been collected for that target by Oracle Management Agent.

APM Mining Performance Details Metrics

Metric	Description
Average CPU Utilization (%)	Shows the percentage of CPU time over total time consumed by the End-user Performance Mining Engine, during the last run.
CPU Usage Time	Shows the total amount of time consumed by the CPU (in seconds) during the last End-user Performance Analysis run.
End Log Time	Shows the time in the access_log file at which the End-user Performance Mining Engine stopped processing.
Number of Beacon Request Lines	Shows the number of log lines with beacon transaction requests (these lines are ignored by the End-user Performance Mining Engine and are not reported in the End-User Performance Monitoring analysis).
Output - Completed Pages	Shows the number of completed pages for which End-User Performance Monitoring data was reported.
Output - Incompleted Pages	Shows the number of partially loaded pages reported by the End-user Performance Mining Engine.
Number of Invalid Log Lines	Shows the number of lines that are not recognized by the End-user Performance Mining Engine.
Number of Log Lines Processed	Shows the number of access_log lines processed by the End-user Performance Mining Engine.
Output - Total Page Requests	Shows the total number of component requests reported for all pages.
Start Log Time	Shows the time in the access_log file at which the End-user Performance Mining Engine started processing.
Start Run Time	Shows the time at which the End-user Performance Mining Engine started running.
EUM Gif Requests - Total	Shows the total number of EUM Gif requests in the access_log that signal the completion of a page load.
EUM Gif Requests - No Expected Output	Shows the number of EUM Gif requests for which output is not reported. These include component pages that are parts of a single page load, where only the main page is reported.
EUM Gif Requests - Browser Cached Pages	Shows the number of EUM Gif requests for pages that are cached, and hence no End-User Performance Monitoring information is available.
EUM Gif Requests - Other/Unaccounted	Shows the number of EUM Gif requests for which output is not reported for other reasons.
Total Run Time (sec)	Shows the total amount of time taken by the End-user Performance Mining Engine.
