Installation guide on MAC

Can be configured in any OS similary

Install Supervisor Package with brew install supervisor or see Installation Guide for any other OS.

Once installed this will create supervisord.ini file in /usr/local/etc which is a config file

Rename this file to supervisord.conf so that we can start supervisor with command supervisorctl -c /usr/local/etc/supervisord.conf (by default supervisor creates supervisord.ini which throws error should be conf file)

Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward the edit command to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

Enable SSL in Apache (OSX)

The following will guide you through the process of enabling SSL on a Apache webserver

The instructions have been verified with OSX El Capitan (10.11.2) running Apache 2.4.16
The instructions assume you already have a basic Apache configuration enabled on OSX, if this is not the case feel free to consult Gist: "Enable Apache HTTP server (OSX)"

Apache SSL Configuration

Create a directory within /etc/apache2/ using Terminal.app: sudo mkdir /etc/apache2/ssl
Next, generate two host keys:

	filebeat.prospectors:
	- type: log
	paths:
	- /path/to/log1
	tags: ["log1"]
	- type: log
	paths:
	- /path/to/custom_geo_json_log
	tags: ["custom-geo-json-log"]
	output.logstash: #sending it to logstash instance
