ngx

NGINX access log parser and filter by fields or values with output to JSON or plain text

NGX

CLI tool for parsing NGINX access log and filtering by fields or values with output to JSON or plain text

Status

Pre-alpha, don't use on production.

Installation

git clone https://github.com/creadone/ngx && cd ngx && shards build --release

Usage

The main difference between the filter and find that the filter returns only subset of the fields and nothing more, and the find can compare by value of fields but always returns all fields.

Finder mode

Fields

ip, user, day, month, year, hour, minute, second, timezone, method, path, protocol, version, code, bytes, referer, user_agent

Input logs

127.0.0.1 - - [30/Oct/2020:10:27:00 +0000] "GET / HTTP/1.1" 200 0 "-" "ApacheBench/2.3"
127.0.0.1 - - [30/Oct/2020:10:27:00 +0000] "GET / HTTP/1.1" 200 0 "-" "ApacheBench/2.3"
127.0.0.1 - - [30/Oct/2020:10:27:00 +0000] "GET / HTTP/1.1" 200 0 "-" "ApacheBench/2.3"

Run ngx

cat access.log | ngx -m find -f ip=127.0.0.1, method=GET -o json

Output

TODO

  1. Tests
  2. Merge finder and filter into one
  3. Custom parsing templates
  4. Add expressions to comparison: cat access.log | ngx -m find -f code > 400, ip << 127.0.0.1/24 -o json
  5. Export output with TCP or HTTP
