Structured Logging is a logging technique that organizes log entries in a structured format, making it easier to analyze, search, and understand the logs.
š Note: Structured logs are a must for any production application to ensure efficient debugging, monitoring, and auditing.
Log structuring refers to organizing log entries in a consistent and predictable manner. This helps in easy analysis and understanding of logs.
Contextual Logging involves adding contextual data, such as user ID, request ID, or timestamp, to the log entries. This helps in tracing the origin and context of the log entry.
Semantic Logging involves adding semantic information, such as log levels (error, warning, info, etc.), to the log entries. This helps in understanding the severity and importance of the log entry.
To set up logging in ASP .NET, we'll use the Microsoft.Extensions.Logging library. This library allows us to add various logging providers, such as Console, Debug, EventLog, etc.
To write structured logs in ASP .NET, we'll create a custom logger that accepts log levels, contextual data, and semantic information.
To log exceptions, we'll use the Exception property of the LogEntry object, which contains all the details about the exception.
public void LogInfo(string message)
{
var logger = Log.CreateLogger<HomeController>();
logger.LogInformation(message);
}public void LogRequest(string requestId, string message)
{
var logger = Log.CreateLogger<HomeController>();
var logEntry = new LogEntry(LogLevel.Information, requestId, "Request", message);
logger.Write(logEntry);
}What is the main advantage of Structured Logging?
