Installation

Install via Package Manager

Install-Package WatchDog.NET --version 1.3.2

Usage

To enable WatchDog to listen for requests, use the WatchDog middleware provided by WatchDog.

Add WatchDog Namespace in Startup.cs

using WatchDog;

Register WatchDog service in Startup.cs under ConfigureService()

services.AddWatchDogServices();

Setup AutoClear Logs Optional

This clears the logs after a specific duration.

services.AddWatchDogServices(opt => 
{ 
   opt.IsAutoClear = true; 
});

NOTE When IsAutoClear = true Default Schedule Time is set to Weekly, override the settings like below:

services.AddWatchDogServices(opt => 
{ 
   opt.IsAutoClear = true;
   opt.ClearTimeSchedule = WatchDogAutoClearScheduleEnum.Monthly;
});

Setup Logging to External Db (MSSQL, MySQL & PostgreSQL) Optional

Add Database Connection String and Choose SqlDriver Option

services.AddWatchDogServices(opt => 
{
   opt.IsAutoClear = false; 
   opt.SetExternalDbConnString = "Server=localhost;Database=testDb;User Id=postgres;Password=root;"; 
   opt.SqlDriverOption = WatchDogSqlDriverEnum.PostgreSql; 
});

Add WatchDog middleware in the HTTP request pipeline in Startup.cs under Configure()

NOTE Add Authentication option like below: Important

This authentication information (Username and Password) will be used to access the log viewer.

app.UseWatchDog(opt => 
{ 
   opt.WatchPageUsername = "admin"; 
   opt.WatchPagePassword = "Qwerty@123"; 
 });

NOTE If your project uses authentication, then app.UseWatchDog(); should come before app.UseRouting(), app.UseAuthentication(), app.UseAuthorization(), app.UseEndpoints() in that order

Add list of routes you want to ignore by the logger: Optional

List of routes, paths or specific strings to be ignored should be a comma separated string like below.

app.UseWatchDog(opt => 
{ 
   opt.WatchPageUsername = "admin"; 
   opt.WatchPagePassword = "Qwerty@123"; 
   opt.Blacklist = "Test/testPost, weatherforecast";
 });

Add WatchDog Exception Logger Optional

This is used to log in-app exceptions that occur during a particular HTTP request.

NOTE Add Exception Logger before the main WatchDog Middleware, preferably at the top of the middleware hierarchy so as to catch possible early exceptions.

app.UseWatchDogExceptionLogger();

...

app.UseWatchDog(opt => 
{ 
   opt.WatchPageUsername = "admin"; 
   opt.WatchPagePassword = "Qwerty@123"; 
   opt.Blacklist = "Test/testPost, weatherforecast";
 });

Log Messages/Events

WatchLogger.Log("...TestGet Started...");

View Logs and Exception

Start your server and head to /watchdog to view the logs.

Example: https://myserver.com/watchdog or https://localhost:[your-port]/watchdog

Still confused? Check out the implementation in the WatchDogCompleteTestAPI folder or the .NET 6 implementation in the WatchDogCompleteApiNet6 folder.
