Setting Up Serilog with Elasticsearch

First things first, make sure you have the necessary packages installed via NuGet:

Install-Package Serilog
Install-Package Serilog.Sinks.Elasticsearch

Configuration with SerilogConfig

To manage Serilog settings such as log levels, Elasticsearch connection details, and authentication credentials, we’ll use a configuration class called SerilogConfig. This class can be loaded from a JSON file (serilog-config.json), making it easy to tweak settings without rebuilding your application.

public class SerilogConfig
{
    public string MinimumLevel { get; set; }
    public List<Uri>? Uris { get; set; }
    public Uri? Uri { get; set; }
    public string? Index { get; set; }
    public string? Username { get; set; }
    public string? Password { get; set; }
    public string? ApiKeyAuthentication { get; set; }
    public string? CertificateFingerprint { get; set; }
}
