logstasher

Erlang Logger formatter for logstash

Hex package

In rebar.config, add the logstasher Hex package to the deps:

{deps, [
    {logstasher, "~> 1.0.0"}
]}.

Erlang Configuration

In sys.config, enable logstasher_h as a Logger handler and configure the logstasher application:

[
     {kernel, [
         {logger, [
             {handler, logstash, logstasher_h,
                 #{
                     level => info
                 }
             }
         ]}
     ]},

     {logstasher, [
         {transport, udp},     % tcp | udp | console
         {host, "localhost"},  % inet:hostname()
         {port, 5000}          % inet:port_number()
     ]}
 ].

After this, also add the logstasher application to your .app.src file:

{applications, [
   ....
   logstasher,
   ....
]},

Logstash Configuration

input {
  udp {
    codec => json
    port => 5000
    queue_size => 10000
    workers => 10
    type => default_log_type
  }
}
output {
  stdout {}
  elasticsearch {
    protocol => http
  }
}

Send data to logstash

It is possible to send other data to logstash:

logstasher:send_message(<<"Hello world!">>, #{ some => <<"fields">> }).

A timestamp will be added to the message.
