# Nginx Error Log Parser

Parses nginx error.log and access.log files using pattern matching for 5xx status codes, upstream timeouts, and SSL handshake failures. Correlates error spikes with nginx -T configuration dumps to identify misconfigured proxy_pass and keepalive settings.

## Installation

Use the upstream install or setup path that matches your environment:
- git clone https://github.com/nginx/nginx.git
- make

Requirements and caveats from upstream:
- Processes synchronize data through shared memory. For this reason, many NGINX directives require the allocation of shared memory zones. As an example, when configuring [rate limiting](https://nginx.org/en/docs/http/ng...
- Most Linux distributions will require several dependencies to be installed in order to build NGINX. The following instructions are specific to the apt package manager, widely available on most Ubuntu/Debian distributi...
- Prior to building NGINX, you must run the configure script with [appropriate flags](https://nginx.org/en/docs/configure.html). This will generate a Makefile in your NGINX source root directory that can then be used to...

- While nearly all popular Linux-based operating systems are distributed with a community version of nginx, we highly advise installation and usage of official [packages](https://nginx.org/en/linux_packages.html) or sou...
