Overview

Popcorn is a log aggregator and analyzer for your server logs. Its purpose is to provide a single interface where you can see what’s going on in your code, what’s happening with your servers and quickly detect problems caused by changes.

Features

• Send logs in realtime using UDP, don’t block your running app
• Data encoded using protocol buffers for efficiency
• Log messages are categorized by node, node type, node version, severity and date
• Easily connect your app log messages from many platforms with available clients

Configuration

Add popcorn as a dependency to an existing Erlang/OTP app by adding a reference in the rebar.config file.

Your app should supply a configuration for popcorn, which includes the user authentication policy. Possible options in the config are:

#+BEGIN EXAMPLE “`erlang {popcorn, [ {udp_listen_port, 9125}, {http_listen_port, 9125}, {http_auth_enabled, true}, {http_auth_db_type, config}, {http_auth_users, [{<<”log_user”>>, <<”log_password”>>}]}, {log_retention, [{<<”debug”>>, {hours, 2}}, {<<”info”>>, {hours, 2}}, {<<”notice”>>, {hours, 2}}, {<<”warn”>>, {hours, 2}}, {<<”error”>>, {months, 1}}, {<<”critical”>>, {months, 1}}, {<<”alert”>>, {months, 1}}, {<<”emergency”>>, {months, 1}}]} ]} “` #+END EXAMPLE

Requirements

• Erlang R15B01 or later is required (for Cowboy dependency)

Accessing

By default, the server will listen on port 9125 (both UDP and HTTP), so after running, visit http://{host}:9125 and you should see a login screen.
