Debugging in Elastic Search

ShubhamSaxena8 · April 3, 2024, 7:03am

Hello Team,

I need some suggestion related to debugging in Elasticsearch. I am kind of stuck because I am not getting any errors in Elastic console or dotnet console.

I am trying to implement centralized logging system for our dotnet applications. I am using Serilog Nuget package for this.

I have configured Logger in StartUp.cs file but still logs are not sent to my locally running elasticsearch service.

I am not seeing any indices in Kibana.

I am following some Youtube videos where they run Elastic Search and Kibana locally using Docker and then configure dotnet app as shown below but in their case indices were created.

Code:

StartUp.cs

var builder = WebApplication.CreateBuilder(args);


ConfigureLogger();
builder.Host.UseSerilog();

// Add services to the container.
builder.Services.AddControllers();


void ConfigureLogger()
{

    var configuration = new ConfigurationBuilder()
        .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
        .Build();

    var elasticUri = configuration.GetSection("ElasticConfiguration:Uri").Value.ToString();
    Console.WriteLine(elasticUri);
    Console.WriteLine($"cores-{DateTime.UtcNow:yyyy-MM-dd}");

    Log.Logger = new LoggerConfiguration()
    .Enrich.FromLogContext()
    .Enrich.WithMachineName()
    .WriteTo.Debug()
    .WriteTo.Console()
    .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(elasticUri))
    {
        AutoRegisterTemplate = true,
        NumberOfReplicas = 2,
        NumberOfShards = 2,
        IndexFormat = $"cores-{DateTime.UtcNow:yyyy-MM-dd}"
    })
    .Enrich.WithProperty("Environment", "Development")
    .ReadFrom.Configuration(configuration)
    .CreateLogger();
}

appsettings.json

"Serilog": {
    "MinimumLevel": {
      "Default": "Verbose",
      "Override": {
        "Microsoft": "Information",
        "System": "Warning"
      }
    }
  },
  "ElasticConfiguration": {
    "Uri": "http://localhost:9200/"
  },

I am not a .NET developer and have never used Serilog. There are however some additional information that would be useful to have though.

What version of Elasticsearch are you using?

Is your cluster secured?

What is the size and specification of your Elasticsearch cluster?

Is Elasticsearch running on the same host as the application you are collecting logs from?

Hello Chris,

I am using version 8.12.2 for both elasticsearch and kibana.

I have disabled the security for Elasticsearch.

Not sure about clustering part since I am running it locally from the zip I downloaded from elasticsearch site. I haven't changed anything in the clustering related settings so that part is commented by default.

Can you guide me on these settings?

Regards

Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.

Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

Hello team,

I am using version 8.12.2 for both elasticsearch and kibana.

I have disabled the security for Elasticsearch.

# Enable security features
xpack.security.enabled: false

xpack.security.enrollment.enabled: false

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: false
  keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: false
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12

Not sure about clustering part since I am running it locally from the zip I downloaded from elasticsearch site. I haven't changed anything in the clustering related settings so that part is commented by default.

# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1

Can you guide me on these settings?

Could you share Elasticsearch logs please? From the start.

ShubhamSaxena8 · April 5, 2024, 9:10am

Hello David,

Sorry, I am new to Elasticsearch so don't know where I can find the latest logs. I can see multiple log files like (gc.log, gc.log.31, etc) in the logs folder.

Can I upload a file here, because I don't see any option to do so?

I am running elasticsearch on my local through a zip I downloaded from Elasticsearch site.

Regards,
Shubham Saxena

it's often named elasticsearch.log.

You can paste the logs within the post but please format them. Please read this about how to format.

So Elasticsearch is running at 172.17.112.1:9200

I guess you need to use this address from the machine which is sending logs.

As @Christian_Dahlqvist said earlier, replace:

  "ElasticConfiguration": {
    "Uri": "http://localhost:9200/"
  },

with:

  "ElasticConfiguration": {
    "Uri": "http://172.17.112.1:9200/"
  },

If this does not work, please run something like:

curl http://172.17.112.1:9200/

from the machine where your app is running. Not from Elasticsearch machine.

ShubhamSaxena8 · April 8, 2024, 9:40am

Hello David,

I am working on 1 single machine and all the applications (elasticsearch, kibana and dotnet application) are running locally.

I also changed the configuration (URI) as suggested but still no luck.

I tried it using Azure Elasticsearch service (by default is uses standard license) and it worked for me, but we want to use the Basic free license and in that, there is no security tab in stack management system.

Since I don't have access to security tab, I am not able to create API-key which I can provide while configuring the Elasticsearch in dotnet.

Is it necessary to provide the API-key to ingest the data?

Regards,
Shubham

dadoonet · April 8, 2024, 9:53am

Basic license comes with security. Not all but a lot of features. You probably disabled security by yourself.

Anyway, did you try to run the curl command I mentioned ? What is the output ?

ShubhamSaxena8 · April 8, 2024, 10:51am

I'll Check for the security part in the elastic.yaml file.

The below settings were set to false earlier, is there anything else that I should look into:

# Enable security features
xpack.security.enabled: true

xpack.security.enrollment.enabled: true

Here's the output of the curl command:

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "3oW2Fx2EQkaSlj1A5_DzmA",
  "version" : {
