QuackAlert
5xx errors in production?
Get notified instantly.
Lightweight library for .NET that monitors your application and sends email alerts when something goes wrong. Setup in under 2 minutes.
Set up in two simple steps
No complexity. No unnecessary boilerplate.
Add configuration to appsettings.json
{
"QuackAlert": {
"Enabled": true,
"Environment": "Production",
"Email": {
"SmtpHost": "smtp.gmail.com",
"SmtpPort": 587,
"SmtpUser": "your-email@gmail.com",
"SmtpPassword": "your-app-password",
"From": "your-email@gmail.com",
"To": "recipient@email.com",
"EnableSsl": true
}
}
}Security best practice
In production environments, avoid storing sensitive email configuration values directly in appsettings.json
Prefer supplying these values through environment variables, for example QuackAlert__Email__SmtpPassword
Any values defined in appsettings.json will be automatically overridden when the corresponding environment variables are provided
Register middleware in your startup pipeline
using QuackAlert.Extensions;
builder.Services.AddQuackAlert(options => {
builder.Configuration
.GetSection("QuackAlert")
.Bind(options);
});
var app = builder.Build();
app.UseQuackAlert();Roadmap
