Plack::Middleware::AxsLog - Yet another AccessLog Middleware
use Plack::Builder; builder { enable 'AxsLog', combined => 1, response_time => 1, error_only => 1, $app };
Alternative implementation of Plack::Middleware::AccessLog. This middleware supports response_time and content_length calculation AxsLog also can set condition to display logs by response_time and status code.
Originally, AxsLog was faster AccessLog implementation. But PM::AccessLog became to using same access-log generator module Apache::LogFormat::Compiler. Two middlewares have almost same performance now.
log format. if disabled, "common" format used. default: 1 (combined format used)
common (Common Log Format) format is
%h %l %u %t \"%r\" %>s %b => 127.0.0.1 - - [23/Aug/2012:00:52:15 +0900] "GET / HTTP/1.0" 200 645
combined (NCSA extended/combined log format) format is
%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\" => 127.0.0.1 - - [23/Aug/2012:00:52:15 +0900] "GET / HTTP/1.1" 200 645 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.79 Safari/537.1"
use ltsv log format. default: 0
LTSV (Labeled Tab-separated Values) format is

A format string.

Adds time taken to serve the request. default: 0. This args effect to common, combined and ltsv format.
Display logs if response status is error (4xx or 5xx). default: 0
Display log if time taken to serve the request is above long_response_time. default: 0 (all request logged)
Callback to print logs. default:none ( output to psgi.errors )
use File::RotateLogs; my $logger = File::RotateLogs->new(); builder { enable 'AxsLog', logger => sub { $logger->print(@_) } $app };
