DataDog logger doesn't log INFORMATION level


I have .NET 5 web app which is supposed to write logs to DataDog using Serilog Sink (Serilog.Sinks.Datadog.Logs v0.5.2). Here is my Program.cs:

static async Task Main(string[] args)
{
    using (var log = new LoggerConfiguration()
        .MinimumLevel.Verbose()
        .WriteTo.DatadogLogs("HERE IS MY API KEY", service: "myservice", configuration: new DatadogConfiguration() { Url = "https://http-intake.logs.us3.datadoghq.com" })
        .CreateLogger())
    {
        log.Debug("debug");
        log.Information("information");
        log.Verbose("verbose");
        log.Warning("warning");
        log.Error("error");
        log.Fatal("fatal");
    }

    using IHost host = CreateHostBuilder(args).Build();

    await host.RunAsync();
}

After running the app i can see all these logs in DataDog EXCEPT Information logs. So, i see only 5 messages instead of 6. What i'm doing wrong?


Solution

  • The reason turned out to be on DataDog side. There was an indexation rule set up in our Logs Configuration that is telling to exclude 99% of all INFO logs (DataDog > Logs > Configuration > Indexes tab). Disabling this rule solved the issue.
