Identifying slow database commands via logging in ASP.NET Core

we can log SQL generate by Linq and can check for performance

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder
        .UseSqlServer(@"Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;ConnectRetryCount=0")
        .LogTo(Console.WriteLine, LogLevel.Information);
}


When the logging level is set at LogLevel.Information, EF emits a log message for each command execution with the time taken:

info: 06/12/2020 09:12:36.117 RelationalEventId.CommandExecuted[20101] (Microsoft.EntityFrameworkCore.Database.Command)
      Executed DbCommand (4ms) [Parameters=[], CommandType='Text', CommandTimeout='30']
      SELECT [b].[Id], [b].[Name]
      FROM [Blogs] AS [b]
      WHERE [b].[Name] = N'foo'


With logging we can see we are getting Execution time :Executed DbCommand (4ms)
