Cách setup Logging Elastic Search & Kibana using SeriLog trong dự án Microservice NET Core API

Answer 1

B1: Cài đặt các gói nuget cho các services

- nuget Serilog.AspNetCore
- nuget Serilog.Enrichers.Environment
- nuget Serilog.Sinks.Elasticsearch

Answer 2

B2: Add config SeriLog và Elastic trong appsetting.json

"Serilog": {
  "MinimumLevel": {
    "Default": "Information",
    "Override": {
      "Microsoft": "Information",
      "System": "Warning"
    }
  }
},
"ElasticConfiguration": {
  "Uri": "{host_url}:9200"
}

Answer 3

B3: Đăng ký SeriLog và ElasticSearch trong program.cs

var environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");

var configuration = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json",
optional: true)
.Build();

Log.Logger = new LoggerConfiguration()
.Enrich.FromLogContext()
.Enrich.WithMachineName()
.WriteTo.Debug()
.WriteTo.Console()
.WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(configuration["ElasticConfiguration:Uri"]))
{
AutoRegisterTemplate = true,
IndexFormat = $"{Assembly.GetExecutingAssembly().GetName().Name.ToLower().Replace(".", "-")}-{environment?.ToLower().Replace(".", "-")}-{DateTime.UtcNow:yyyy-MM}"
})
.Enrich.WithProperty("Environment", environment)
.ReadFrom.Configuration(configuration)
.CreateLogger();

builder.Host.UseSerilog();

B4: Triển khai ElasticSearch trên docker-compose.yml

  elasticsearch:
    container_name: elasticsearch
    image: docker.elastic.co/elasticsearch/elasticsearch:7.9.1
    ports:
      - 9200:9200
    volumes:
      - elasticsearch-data:/usr/share/elasticsearch/data
    environment:
      - xpack.monitoring.enabled=true
      - xpack.watcher.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
    networks:
      - elastic
  kibana:
    container_name: kibana
    image: docker.elastic.co/kibana/kibana:7.9.1
    ports:
      - 5009:5601
    depends_on:
      - elasticsearch
    environment:
      - ELASTICSEARCH_URL=http://dev-api.hoomee.vn:9200
