What does this thing do?

This ASP.NET sample application demonstrates how to send SMS alerts to a list of system administrators if something goes wrong on your server. In this tutorial, we'll show you the key bits of code to make this work.

See how EMC uses Twilio SMS to send IT alerts to 68,000 employees.

Let's get started!

List server admins

Create a list of administrators who should be notified if a server error occurs. The only requirement we have is a PhoneNumber.

Configure Twilio client

In order to send a message we'll need to initialize the Twilio C# Helper Library, which requires reading our TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN defined at ServerNotifications.Web/Web.config

Handle all application errors

In an ASP.NET MVC application, we can handle errors at the application level. Note that any other exceptions caught in the code (using your own try/catch blocks) are not being captured and processed here.

Create a custom alert message

Here we create an alert message to send out via text message. You might also decide to include a picture with your alert message, maybe a screenshot of the application when the crash happened?

Reading the admins from the CSV file

Next we read the admins from our CSV file. We use the method GetRecords to read all the records.

Sending a text message

There are the three parameters needed to send an SMS using the Twilio REST API: From, To, and Body. US and Canadian phone numbers can also send an image with the message.
