Install via Package Manager

Install-Package WatchDog.NET --version 1.4.11


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()


Setup AutoClear Logs Optional

This clears the logs after a specific duration.

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 & MongoDb) Optional

Add Database Connection String and Choose DbDriver Option

services.AddWatchDogServices(opt => 
   opt.IsAutoClear = true; 
   opt.SetExternalDbConnString = "Server=localhost;Database=testDb;User Id=postgres;Password=root;"; 
   opt.DbDriverOption = WatchDogDbDriverEnum.PostgreSql; 

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

Login page sample

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 after app.UseRouting(), app.UseAuthentication(), app.UseAuthorization(), in that order

Request and Response Sample Details

Optional Configurations: Optional
  • Blacklist: List of routes, paths or endpoints to be ignored (should be a comma separated string like below).
  • Serializer: If not default, specify the type of global json serializer/converter used.
  • CorsPolicy: Policy Name if project uses CORS.
  • UseOutputCache: If your application uses ASP.NET Output Cache. This feature is only available for .NET8 and above.
  • UseRegexForBlacklisting: Enables the use of Regex to blacklist request routes, paths or endpoints.
app.UseWatchDog(opt => 
   opt.WatchPageUsername = "admin"; 
   opt.WatchPagePassword = "Qwerty@123"; 
   opt.Blacklist = "Test/testPost, api/auth/login"; //Prevent logging for specified endpoints
   opt.Serializer = WatchDogSerializerEnum.Newtonsoft; //If your project use a global json converter
   opt.CorsPolicy = "MyCorsPolicy";
   opt.UseOutputCache = true;
   opt.UseRegexForBlacklisting = true;
Add WatchDog Exception Logger Optional

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

Exception Sample Details

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.UseWatchDog(opt => 
   opt.WatchPageUsername = "admin"; 
   opt.WatchPagePassword = "Qwerty@123";

 .ConfigureLogging( logging =>
 .ConfigureWebHostDefaults(webBuilder =>
