Application for sending logs to Logstash.
Inspired by lager_logstash.
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
}}
]}
]}
].- outputs:
tcp,udp,file - formats:
json,json_lines,msgpack
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.
