Logstash + Elasticsearch + Kibana

Logstash + Elasticsearch + Kibana is one of powerful solutions for log aggregation / dashboard [1]
You can use it to aggregate logs from several BrandMeister servers, simplify search or make technical dashboards.
BrandMeister provides direct interface to Logstash to provide log reports as well as internal event's data.

Configuration

It's highly recommended to install ELK stack to the separate machine. Logstash's certificate can be self-signed, BrandMeister accepts any.

BrandMeister.conf

LumberJack :
{
  address = "localhost";  // Logstash address
  port = 10514;           // Logstash port configured to accept Lumberjack protocol
  options = 3;            // Bit field: bit 0 - transmit log reports, bit 1 - transmit system events
  capacity = 1024;        // Buffer capacity (line count)
};

/etc/logstash/conf.d/lumberjack.conf

input {
  lumberjack {
    id => 'lj'
    host => '127.0.0.1'
    port => 10514
    ssl_certificate => '/etc/logstash/logstash.crt'
    ssl_key => '/etc/logstash/logstash.key'
    type => lumberjack
  }
}

filter {
  date {
    match => [ 'timestamp', 'ISO8601' ]
  }
  ruby {
    path => '/opt/BrandMeister/brandmeister-logstash.rb'
  }
}

output {
  elasticsearch {
    hosts => [ 'localhost:9200' ]
  }
}
