SerilogSinkForPostgreSQL

SerilogSinkForPostgreSQL is a library to save logging information from Serilog to PostgreSQL. The assembly was written and tested in .Net Framework 4.8 and .Net Standard 2.0.

Available for

• NetFramework 4.5
• NetFramework 4.6
• NetFramework 4.6.2
• NetFramework 4.7
• NetFramework 4.7.2
• NetFramework 4.8
• NetStandard 2.0

Basic usage:

string connectionString = "User ID=serilog;Password=serilog;Host=localhost;Port=5432;Database=Logs";

string tableName = "logs";

IDictionary<string, ColumnWriterBase> columnWriters = new Dictionary<string, ColumnWriterBase>
{
    { "message", new RenderedMessageColumnWriter(NpgsqlDbType.Text) },
    { "message_template", new MessageTemplateColumnWriter(NpgsqlDbType.Text) },
    { "level", new LevelColumnWriter(true, NpgsqlDbType.Varchar) },
    { "raise_date", new TimestampColumnWriter(NpgsqlDbType.Timestamp) },
    { "exception", new ExceptionColumnWriter(NpgsqlDbType.Text) },
    { "properties", new LogEventSerializedColumnWriter(NpgsqlDbType.Jsonb) },
    { "props_test", new PropertiesColumnWriter(NpgsqlDbType.Jsonb) },
    { "machine_name", new SinglePropertyColumnWriter("MachineName", PropertyWriteMethod.ToString, NpgsqlDbType.Text, "l") }
};

var logger = new LoggerConfiguration()
	.WriteTo.PostgreSQL(connectionString, tableName, columnWriters)
	.CreateLogger();

The project can be found on nuget.

Table auto creation:

If you set parameter needAutoCreateTable to true, the sink will automatically create the table.

string connectionString = "User ID=serilog;Password=serilog;Host=localhost;Port=5432;Database=Logs";

string tableName = "logs";

IDictionary<string, ColumnWriterBase> columnWriters = new Dictionary<string, ColumnWriterBase>
{
    { "message", new RenderedMessageColumnWriter(NpgsqlDbType.Text) },
    { "message_template", new MessageTemplateColumnWriter(NpgsqlDbType.Text) },
    { "level", new LevelColumnWriter(true, NpgsqlDbType.Varchar) },
    { "raise_date", new TimestampColumnWriter(NpgsqlDbType.Timestamp) },
    { "exception", new ExceptionColumnWriter(NpgsqlDbType.Text) },
    { "properties", new LogEventSerializedColumnWriter(NpgsqlDbType.Jsonb) },
    { "props_test", new PropertiesColumnWriter(NpgsqlDbType.Jsonb) },
    { "machine_name", new SinglePropertyColumnWriter("MachineName", PropertyWriteMethod.ToString, NpgsqlDbType.Text, "l") }
};

var logger = new LoggerConfiguration()
	.WriteTo.PostgreSQL(connectionString, tableName, columnWriters, needAutoCreateTable: true)
	.CreateLogger();

You can change column sizes by setting the values in the TableCreator class:

// Sets size of all BIT and BIT VARYING columns to 20
TableCreator.DefaultBitColumnsLength = 20;

// Sets size of all CHAR columns to 30
TableCreator.DefaultCharColumnsLength = 30;

// Sets size of all VARCHAR columns to 50
TableCreator.DefaultVarcharColumnsLength = 50;

Mixed case table or column names

Table or column names are always case-sensitive!
