Logging.ExceptionSender

Watches for unhandled exceptions, saves details to text files in specific folder, starts background task that sends exception info to you (MailGun and Telegram are supported, add your own if needed).

Written for console/worker projects that use RecurrentTasks and for ASP.NET projects (via Logging.ExceptionSender.Web).

Main features

• Exception message and stacktrace are captured;
• Last N log records captured (using Logging.Memory package);
• Captured data saved in log subdirectory for later processing;
• Background task (based on RecurrentTasks) checks new exception data;
• Every single exception - one message to you;
• Uses MailGun to send emails (free quota 10K emails/month) or Telegram
• Add your own provider by inheriting from ExceptionSenderTask;
• When new exception is caught - tries to send immediately;
• When message sucessfully sent - files are deleted from disk;
• Can send emails to multiple recipients (multiple To).

Installation

Use NuGet package Logging.ExceptionSender for console/worker projects, or Logging.ExceptionSender.Web for web projects.

Usage

See Sample project.

1. Register at MailGun.com or create a Telegram bot

Put values into appsettings file:

{ "ExceptionSender": { // For Mailgun "MailgunDomain": "example.com", "MailgunApiKey": "key-*************", "From": "myapp@example.com", "To": [ "admin1@example.com", "admin2@example.com" ], // For Telegram "ChatId": "", "BotToken": "" } }

2. Register sender service

services.AddMailgunExceptionSender(Configuration.GetSection("ExceptionSender")); // or services.AddTelegramExceptionSender(Configuration.GetSection("ExceptionSender"));

3. Attach catch service

Append .WithExceptionSender() to task configuration:

services.AddTask<SomeTask>(o => o.AutoStart(...).WithExceptionSender());

Append .UseExceptionSender() to aspnet request pipeline:

app.UseExceptionSender();

4: Enable MemoryLogger with desired log level

var loggerFactory = app.Services.GetRequiredService<ILoggerFactory>(); loggerFactory.AddMemory(LogLevel.Debug);
