每當在看 apache 的 log 檔時,總是覺得畫面密密麻麻的,好多字都看不完,雖然預設的 log 已經提供足夠的訊息讓我們來偵錯或查詢異狀,但總是覺得不夠人性化,也許您會覺得看多了就會習慣,可是換個角度想,如果可以按照自己想要的訊息來紀錄,不是更好嗎,所以才會有這篇文章。
Format String | Description |
%% | 百分比符號 |
%a | 遠端 IP 位址 |
%A | 本機 IP 位址 |
%B | 回應一個 request 的大小 (bytes),含 HTTP headers |
%b | 以 CLF 格式回應一個 request 的大小 (bytes),含 HTTP headers |
%{Foobar}C | 傳送到伺服器的 Foobar cookie 的內容 |
%D | request 傳送到伺服器的時間 (microseconds) |
%{FOOBAR}e | 伺服器環境變數 FOOBAR 的內容 |
%f | 檔名 |
%h | 遠端主機名稱 |
%H | request 的通訊協定 |
%{Foobar}i | The contents of Foobar: header line(s) in the request sent to the server. Changes made by other modules (e.g. mod_headers) affect this. |
%k | 在一個 connection requests handled 中 keepalive 的數量 |
%l | 遠端的 logname (This will return a dash unless mod_ident is present and Identity Check is set On). |
%m | The request method. |
%{Foobar}n | The contents of note Foobar from another module. |
%{Foobar}o | The contents of Foobar: header line(s) in the reply. |
%p | 伺服器回應一個 request 的 canonical port number |
%{format}p | The canonical port of the server serving the request or the server's actual port or the client's actual port. Valid formats are canonical, local, or remote. |
%P | 回應 request 時的 PID |
%{format}P | The process ID or thread id of the child that serviced the request. Valid formats are pid, tid, and hextid. hextid requires APR 1.2.0 or higher. |
%q | The query string (prepended with a ? if a query string exists, otherwise an empty string). |
%r | First line of request. |
%s | 狀態. 若是由內部轉址來的 request,則將顯示原始 request 的狀態 |
%t | 伺服器收到 request 的時間 (standard english format) |
%{format}t | 同上,但以自訂的格式來顯示時間 |
%T | 伺服器回應 request 的時間 (in seconds) |
%u | 遠端的使用者 (from auth) |
%U | The URL path requested (not including any query string) |
%v | 伺服器回應 request 時的 canonical ServerName |
%V | The server name according to the UseCanonicalName setting. |
%X | Connection status when response is completed : X:connection aborted before the response completed. +:connection may be kept alive after the response is sent. -:connection will be closed after the response is sent. This directive was %c in late versions of Apache 1.3, but this conflicted with the historical ssl %{var}c syntax. |
%I | Bytes received, including request and headers, cannot be zero. You need to enable mod_logio to use this. |
%O | Bytes sent, including headers, cannot be zero. You need to enable mod_logio to use this. |
