apache - 将Apache日志的精度提高到毫秒

Question

我已经修改了rsyslogd的配置以禁用RSYSLOG_TraditionalFileFormat。
但是，apache日志/var/log/apache/error.log仍然仅显示第二个精度。

还有其他需要配置的内容吗？

在http://httpd.apache.org/docs/current/mod/mod_log_config.html
您会看到不同的时间格式，包括毫秒
只是从

%t 
to 
%{%d/%b/%Y:%T}t-%{msec_frac}t for miliseconds
or
%{%d/%b/%Y:%T}t-%{usec_frac}t for microsecs

例子:
16/三/2013:22:44:34-634
16/三/2013:22:44:34-634200
文档化Apache

%t Time the request was received, in the format [18/Sep/2011:19:18:28 -0400]. The last number indicates the timezone offset from GMT

%{format}t The time, in the form given by format, which should be in an extended strftime(3) format (potentially localized). If the format starts with begin: (default) the time is taken at the beginning of the request processing. If it starts with end: it is the time when the log entry gets written, close to the end of the request processing. In addition to the formats supported by strftime(3), the following format tokens are supported:

sec number of seconds since the Epoch

msec number of milliseconds since the Epoch

usec number of microseconds since the Epoch

msec_frac millisecond fraction

usec_frac microsecond fraction

These tokens can not be combined with each other or strftime(3) formatting in the same format string. You can use multiple %{format}t tokens instead.
