2. add Below code in programe.cs or startup.cs

using var loggerFactory = LoggerFactory.Create(builder => { builder.AddOpenTelemetry(options => options .AddElasticsearchExporter(new ElasticsearchExporterHttpOptions("telemetry", "http://localhost:9200")) ); });

"telemetry": this is index name in Elasticsearch for which data will be pushed

"http://localhost:9200": This is url of Elasticsearch server.

Example:

internal class Program { private static ActivitySource activitySource = new ActivitySource("OTel.POC.Web", "ASP.NET Core 5.0"); private static void Main(string[] args) { Activity.DefaultIdFormat = ActivityIdFormat.W3C; Activity.ForceDefaultIdFormat = true; using var loggerFactory = LoggerFactory.Create(builder => { builder.AddOpenTelemetry(options => options .AddElasticsearchExporter(new ElasticsearchExporterHttpOptions("telemetry", "http://localhost:9200")) ); }); using (var activity = activitySource.StartActivity("ActivityName")) { var logger = loggerFactory.CreateLogger<Program>(); logger.LogInformation("Hello from {name} {price}.", "tomato", 2.99); Stopwatch s = new Stopwatch(); s.Start(); Stopwatch s1 = new Stopwatch(); long[] timekeeping = new long[1000]; for (int i = 0; i < 1000; i++) { s1.Reset(); s1.Start(); logger.LogInformation($"Counting from {i} to 100"); s1.Stop(); timekeeping[i] = s1.ElapsedMilliseconds; } s.Stop(); Console.WriteLine($"Time Elapsed - {s.ElapsedMilliseconds} ms"); Console.WriteLine("Average time takemn:"+ timekeeping.Average()+" ms"); } Console.ReadLine(); } }
