|
|
* ApacheErrorLogParser |
|
25
|
|
|
* |
|
26
|
|
|
* The directive ErrorLogFormat is documented in version 2.4, but not in 2.2 |
|
27
|
|
|
* |
|
28
|
|
|
* Changes between 2.2/2.4: |
|
29
|
|
|
* - time field includes milliseconds in apache 2.4 |
|
30
|
|
|
* - client field includes port number in apache 2.4 |
|
31
|
|
|
* - note sure about pid/tid in apache 2.2 |
|
32
|
|
|
* |
|
33
|
|
|
* Example (default in 2.4): |
|
34
|
|
|
* ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M" |
|
35
|
|
|
* |
|
36
|
|
|
* Example (similar to the 2.2.x format): |
|
37
|
|
|
* ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i" |
|
38
|
|
|
* |
|
39
|
|
|
* #Example (default format for threaded MPMs): |
|
40
|
|
|
* ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i" |
|
41
|
|
|
* |
|
42
|
|
|
* Note that depending on error, some field may be missing from output. |
