Simple Logging API for database interactions (similar to Database.Log) #1199
Comments
Is there a simpler way for logging (e.g. to console for debugging) other than the example described in #2795 by now? |
@leak - not yet, you still need to plug all the low level stuff together |
BTW, just logging everything is relatively simple: db.GetService<ILoggerFactory>().AddProvider(new ConsoleLoggerProvider()); |
@bricelam that needs to go in app startup right since the ServiceProvider is shared between context instances? Otherwise you add it multiple times. |
Hmm yes, I think you're right... |
FYI http://docs.efproject.net/en/latest/miscellaneous/logging.html shows how to achieve the same thing before we have full support for this feature |
Another method is described in this blog. |
Fixes #16200 Fixes #1199 Examples: Log to the Console: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine); ``` Log to the Console for a given level: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, LogLevel.Information)); ``` Log to the Console for specific events: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, new[] { CoreEventId.ContextInitialized, CoreEventId.ContextDisposed })); ``` Log to the Console for specific categories: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, new[] { DbLoggerCategory.Infrastructure.Name, DbLoggerCategory.Update.Name })); ``` Log to the Console with custom filter: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo(Console.WriteLine, (e, l) => e == CoreEventId.SaveChangesCompleted))); ``` Log to the Console for events in specific categories and a given level formatted as a single line using UTC timestamps: ```C# protected override void OnConfiguring(DbContextOptionsBuilder options) => options .UseMyProvider("...") .LogTo( Console.WriteLine, new[] { DbLoggerCategory.Infrastructure.Name, DbLoggerCategory.Update.Name }, LogLevel.Information, SimpleLoggerFormatOptions.SingleLine | SimpleLoggerFormatOptions.DefaultWithUtcTime | )); ```

This would make use of the core logging services without the need to do any wire-up.
We may want a
Database.Log
for SQL and then something likeContext.Log
for everything.The text was updated successfully, but these errors were encountered:
