Integrating Elasticsearch and Kibana in .NET Core Application

  Introduction 

In today's data-driven world, having efficient search capabilities within your application is crucial. Elasticsearch, an open-source, distributed search and analytics engine, is designed for this purpose. Coupled with Kibana, a powerful visualization tool, you can not only search through large datasets quickly but also visualize and analyze your data in real-time.

This blog post will guide you through integrating Elasticsearch and Kibana into your .NET Core application, focusing on setting up efficient search capabilities.

  What is Elasticsearch? 

Elasticsearch is a search engine based on the Lucene library. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Key features include:

  • Distributed: Elasticsearch distributes data and processing across multiple nodes, ensuring high availability and scalability.
  • Full-text search: It offers powerful full-text search capabilities, including complex search queries.
  • Real-time indexing and searching: Elasticsearch provides near real-time search capabilities, making it ideal for applications that require up-to-date search results.
  • RESTful API: Elasticsearch's API is RESTful, making it easy to interact with using HTTP requests.

  What is Kibana? 

Kibana is an open-source data visualization and exploration tool designed to work with Elasticsearch. It provides a web interface for:

  • Visualizing Elasticsearch data: Create charts, graphs, and maps to visualize your data.
  • Exploring data: Use the Discover feature to explore your indexed data and perform searches.
  • Creating dashboards: Combine multiple visualizations into interactive dashboards for monitoring and analysis.
  • Real-time monitoring: Monitor your data and set up alerts for specific events or conditions.

  Prerequisites 

Before we start, ensure you have the following:

  1. Elasticsearch: Installed and running. Download from the official Elasticsearch website.
  2. Kibana: Installed and running. Download from the official Kibana website.
  3. .NET Core 6 or higher: Installed and ready for development. Lower versions of .NET Core are supported, but .NET Core 6 is the latest LTS version, supported until November 2024. .NET Core 8 is expected to be the next LTS release in November 2023, with support through November 2026.

  Setting Up Elasticsearch in .NET Core 

Step 1: Create a New .NET Core Project

WebApp or API

Step 2: Add Elasticsearch NuGet Packages

dotnet add package Elasticsearch.Net
dotnet add package NEST

Step 3: Configure Elasticsearch

  1. Add Configuration: In appsettings.json, add your Elasticsearch URL:

    {
  "Elasticsearch": {
    "Url": "http://localhost:9200"
  }
}

  2. Create Elasticsearch Service: Create a service to handle Elasticsearch interactions.

    using Elasticsearch.Net;
using Microsoft.Extensions.Configuration;
using Nest;
using System;

public class ElasticsearchService
{
    private readonly IElasticClient _elasticClient;

    public ElasticsearchService(IConfiguration configuration)
    {
        var settings = new ConnectionSettings(new Uri(configuration["Elasticsearch:Url"]))
                       .DefaultIndex("default-index");
        _elasticClient = new ElasticClient(settings);
    }

    public async Task IndexDocumentAsync<T>(T document) where T : class
    {
        await _elasticClient.IndexDocumentAsync(document);
    }

    public async Task<ISearchResponse<T>> SearchAsync<T>(Func<SearchDescriptor<T>, ISearchRequest> searchSelector) where T : class
    {
        return await _elasticClient.SearchAsync(searchSelector);
    }
}

  3. Register Elasticsearch Service: Register the service in Startup.cs or Program.cs.

    public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddSingleton<ElasticsearchService>();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseRouting();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }
}

  4. Use Elasticsearch in Controllers: Create a controller to interact with Elasticsearch.

    using Microsoft.AspNetCore.Mvc;
using System.Threading.Tasks;

[ApiController]
[Route("[controller]")]
public class SearchController : ControllerBase
{
    private readonly ElasticsearchService _elasticsearchService;

    public SearchController(ElasticsearchService elasticsearchService)
    {
        _elasticsearchService = elasticsearchService;
    }

    [HttpPost("index")]
    public async Task<IActionResult> IndexDocument([FromBody] object document)
    {
        await _elasticsearchService.IndexDocumentAsync(document);
        return Ok();
    }

    [HttpGet("search")]
    public async Task<IActionResult> Search(string query)
    {
        var response = await _elasticsearchService.SearchAsync<object>(s => s
            .Query(q => q
                .QueryString(d => d
                    .Query(query)
                )
            )
        );

        return Ok(response.Documents);
    }
}

Step 4: Index Existing Data

If you have existing data in your database, you'll need to index it into Elasticsearch.

  1. Create a Data Indexing Service:

    using Microsoft.Extensions.Configuration;
using Nest;
using System;
using System.Collections.Generic;
using System.Threading.Tasks;

public class DataIndexingService
{
    private readonly IElasticClient _elasticClient;

    public DataIndexingService(IConfiguration configuration)
    {
        var settings = new ConnectionSettings(new Uri(configuration["Elasticsearch:Url"]))
                       .DefaultIndex("your-index-name");
        _elasticClient = new ElasticClient(settings);
    }

    public async Task IndexDataAsync<T>(IEnumerable<T> data) where T : class
    {
        var bulkDescriptor = new BulkDescriptor();

        foreach (var item in data)
        {
            bulkDescriptor.Index<T>(op => op
                .Document(item)
            );
        }

        var response = await _elasticClient.BulkAsync(bulkDescriptor);

        if (response.Errors)
        {
            throw new Exception("Failed to index some documents");
        }
    }
}

  2. Load Existing Data: Fetch data from your database.

    using System.Collections.Generic;
using System.Threading.Tasks;
using Dapper;
using Microsoft.Data.SqlClient;

public class DatabaseService
{
    private readonly string _connectionString;

    public DatabaseService(string connectionString)
    {
        _connectionString = connectionString;
    }

    public async Task<IEnumerable<YourDataType>> GetExistingDataAsync()
    {
        using (var connection = new SqlConnection(_connectionString))
        {
            var query = "SELECT * FROM YourTable";
            var data = await connection.QueryAsync<YourDataType>(query);
            return data;
        }
    }
}

  3. Index Existing Data: In Startup.cs or Program.cs, index your existing data at startup.

    public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<DatabaseService>(sp => new DatabaseService("YourConnectionString"));
        services.AddSingleton<DataIndexingService>();
        services.AddControllers();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env, DatabaseService databaseService, DataIndexingService dataIndexingService)
    {
        // Index existing data at startup
        Task.Run(async () =>
        {
            var existingData = await databaseService.GetExistingDataAsync();
            await dataIndexingService.IndexDataAsync(existingData);
        }).GetAwaiter().GetResult();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseRouting();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }
}
