erlogstash

Application for sending logs to Logstash.

Inspired by lager_logstash.

Configuration

Add erlogstash to your rebar.config deps:

{deps, [
    {erlogstash, {git, "https://github.com/Ledest/erlogstash.git", {branch, "master"}}}
]}.

Configure erlogstash app with something like this:

[
    {erlogstash, [
        {outputs, [
            {erlogstash1, {tcp, {172,22,160,38}, 5000}},
            {erlogstash2, {file, "erlogstash2.log"}}
        ]}
    ]}
].

Or/and configure logger:

[
    {erlogstash, [
        {logger, [
            {handler, logstash1, logger_erlogstash_h, #{
                output => {file, "erlogstash.log"},
                % json is default format
            }},
            {handler, logstash2, logger_erlogstash_h, #{
                output => {tcp, "localhost", 5001},
                tags => #{app => myapp, mytag => "my_tag_value"},
                timestamp => iso8601, % default
                format => json_lines
            }},
            {handler, logstash2, logger_erlogstash_h, #{
                output => {udp, {172,22,160,1}, 5000}
                count => true,
                tags => [{app, myapp}, {mytag, <<"MY_TAG_VALUE">>}],
                timestamp => unix_ms,
                format => msgpack
            }}
        ]}
    ]}
].

Features

• outputs: tcp, udp, file
• formats: json, json_lines, msgpack

Warning

Logstash TCP output is quiet stupid and ugly. So it's a bad idea to use tcp output with a format other than json_lines.
