Nginx Log Analyzer

Overview

Analyzes Nginx access logs to provide insights into traffic. It parses nginx logs to determine the number of unique visitors per day and provides a summary of total visitors over the analyzed period.

Defaults

• No side effects, no temp files, no db writes
• Parses pattern /var/log/nginx/access.log*, including .gz files

Options

• Pass --write-db to create or update a simple sqlite database, containing date and visitor count.
• Specify db path with --database <path> to override default

Build

cargo build --release

Note: if you get /usr/bin/ld: cannot find -lsqlite3 collect2: error: ld returned 1 exit status, you'll need the sqlite3 development package:

Debian/Ubuntu:

sudo apt-get install libsqlite3-dev

Red Hat/Fedora/CentOS-based systems:

sudo yum install sqlite-devel

Arch linux:

sudo pacman -S sqlite

macOS:

brew install sqlite
