    elb-log-parser

    npm version Build Status

    A basic parser for ELB access logs, strongly inspired by node-clf-parser https://github.com/jfhbrook/node-clf-parser.

    When I use this npm?

    Install

    npm install -g elb-log-parser
    

    Example command-line usage

    906058675309_elasticloadbalancing_us-east-1_my-elb_20160420T1700Z_10.0.33.113_115hdtdv.log > elb-log-parser
    

    Outputs JSON which can then be further processed with e.g. something like the json tool.

    Example API usage

    node-elb-log-parser$node
    > var parse = require('./index');
    undefined
    > parse('2015-05-13T23:39:43.945958Z my-loadbalancer 192.168.131.39:2817 10.0.0.1:80 0.000086 0.001048 0.001337 200 200 0 57 "GET https://mytest-111.ap-northeast-1.elb.amazonaws.com:443/p/a/t/h?foo=bar&hoge=fuga HTTP/1.1" "curl/7.38.0" DHE-RSA-AES128-SHA TLSv1.2')

    You get the idea.
