Where does the asp net core logging api as default store logs

Introduction

ASP.NET is a popular programming language used for building web applications. One of the key features of ASP.NET is its logging capabilities, which allow developers to track and store logs for debugging and monitoring purposes. In this article, we will explore the storage for logs in ASP.NET Core Logging API.

ASP.NET Core Logging API

ASP.NET Core provides a flexible and extensible logging API that allows developers to log at various levels of severity, such as Information, Warning, Error, and Critical. The logging API supports different logging providers, including console, file, and database.

Default Storage Location for Logs

By default, ASP.NET Core Logging API stores logs in the console output or the debug output window when running the application locally. However, when deploying the application to a production environment, it is important to configure a storage location for logs.

The default storage location for logs in ASP.NET Core depends on the logging provider used. Let's explore some examples:

Example 1: Console Logging Provider

When using the console logging provider, the logs are displayed in the console output. There is no specific storage location for logs in this case.


// Configure console logging
services.AddLogging(logging =>
{
    logging.AddConsole();
});

Example 2: File Logging Provider

If you want to store logs in a file, you can use the file logging provider. By default, the logs are stored in a named “logs” in the application's root .


// Configure file logging
services.AddLogging(logging =>
{
    logging.AddFile("logs/myapp-{Date}.txt");
});

In the above example, logs will be stored in files with names like “myapp-2022-01-01.txt”, where the {Date} placeholder is replaced with the date.

Example 3: Database Logging Provider

If you prefer to store logs in a database, you can use the database logging provider. The logs will be stored in a within the specified database.


// Configure database logging
services.AddLogging(logging =>
{
    logging.AddDatabase(Configuration.GetConnectionString("DefaultConnection"));
});

In the above example, logs will be stored in a table within the database specified by the “DefaultConnection” string.

Conclusion

In conclusion, the default storage location for logs in ASP.NET Core Logging API depends on the logging provider being used. When using the console logging provider, logs are displayed in the console output. For file logging, logs are stored in a folder named “logs” in the application's root directory. And for database logging, logs are stored in a table within the specified database.

It is important to configure the appropriate storage location for logs based on the deployment environment and logging requirements of your ASP.NET Core application.
