Elasticsearch-Logstash-Kibana (ELK) LoggerProvider for .NET Logging

This ElasticsearchLoggerProvider, for Microsoft.Extensions.Logging, writes direct to Elasticsearch, using the Elasticsearch Common Schema (ECS), and has full semantic logging of structured data from message and scope values.

To use, add the Essential.LoggerProvider.Elasticsearch package to your project:

PS> dotnet add package Essential.LoggerProvider.Elasticsearch

Then add the logger provider to your host builder, and the default configuration will write to a local Elasticsearch service:

using Essential.LoggerProvider;

// ...

    .ConfigureLogging((hostContext, loggingBuilder) =>
    {
        loggingBuilder.AddElasticsearch();
    })

Once you have logged some events, open up Kibana (e.g. http://localhost:5601/) and define an index pattern for dotnet-* with the time filter @timestamp.

You can then discover the log events for the index. Some useful columns to add are log.level, log.logger, event.code, message, tags, and process.thread.id.

Structured message and scope values are logged as labels.* custom key/value pairs, e.g. labels.CustomerId.
