MsSQLLoggerService for .Net Core

This service implements the ILoggerService from the MethodResultWrapper nuGet package using an Ms Sql database table as persistence layer

Pre-conditions for this service to work property

The connection string provided should allow inserting rows into a table that should conform to the following DDL.

Log table definition example


    CREATE TABLE [dbo].[ApplicationLog] (

	    [Id]			INT			IDENTITY(1,1) NOT NULL,
	    [UserId]		VARCHAR(36) NULL,
        [CompanyId]		VARCHAR(36) NULL, 
	    [SeverityCode]	CHAR(1) NOT NULL, -- [D]Debug... [F] Fatal (see SeverityEnum)
	    [MachineName]	VARCHAR(50) NOT NULL, -- Environment.MachineName
	    [Topic]			VARCHAR(50) NULL, -- enables to group log items for a given Topic
	    [Context]		VARCHAR(256) NOT NULL, -- membername, filepath, line number...
	    [Message]		NVARCHAR(MAX) NOT NULL, -- the message
	    [CreateDateUtc] DATETIME NOT NULL, -- timestamp in universal central time

	    CONSTRAINT [PK_Log] 
		    PRIMARY KEY CLUSTERED ([Id] DESC)
    );


    GO
    CREATE NONCLUSTERED INDEX [IX_TOPIC]
	    ON [dbo].[ApplicationLog] ([Topic] ASC)
        WHERE [Topic] IS NOT NULL;
    

Columns

Id

The Id column is not required and will not be populted by the service. However it might be convenient to have a primary column sorted DESC so that the last logs will be at the top of a select statement by default.

If you define this column make sure the database will fill it accordingly by for example using the IDENTITY keyword

UserId
  • You can provide your own column name for this column
  • The UserId column persists the identification of the connected user if any
  • This column should be nullable
  • This column should be of type varchar
  • The logger will truncate any info exceding the max column length
CompanyId
  • You can provide your own column name for this column
  • The CompanyId column persists the identification of the company of the connected user if any
  • This column should be nullable
  • This column should be of type varchar
  • The logger will truncate any info exceding the max column length
SeverityCode
  • You can provide your own column name for this column
  • The SeverityCode column persists the MethodResultWrapper.SeverityEnum code
  • This column should be non nullable
  • This column should be of type char (one char is enough)
   // Sevirity enum and corresponding codes
   // -------------------------------------
   public enum SeverityEnum
    {
        Ok, // "O"
        Debug, // "D"
        Info, // "I"
        Warning, // "W"
        Error, // "E"
        Fatal, // "F"
    }
MachineName

  • You can provide your own column name for this column
  • The MachineName column persists Environment.MachineName
  • This column should be non nullable
  • This column should be of type varchar
  • The logger will truncate any info exceding the max column length
Topic

This column lets you group logs for a given topic

  • You can provide your own column name for this column

            var ls = new Logger(
                cs,
                SeverityEnum.Debug,
