Elmah email log

ELMAH (Error Logging Modules and Handlers) is a popular open-source library for.NET that provides a way to log and view exceptions and errors in your application. One of the features of ELMAH is the ability to send error logs via email.

Here's an overview of how to configure ELMAH to send error logs via email:

Step 1: Install ELMAH

You can install ELMAH via NuGet by running the following command in the Package Manager Console:

Install-Package Elmah

Step 2: Configure ELMAH

In your web.config file, add the following configuration settings:

<configuration>
  <elmah>
    <errorLog type="Elmah.ErrorLog, Elmah" />
    <mailSettings>
      <smtp from="[email protected]" />
    </mailSettings>
  </elmah>
</configuration>

In this example, we're configuring ELMAH to use the ErrorLog class to log errors, and setting up the mailSettings section to specify the SMTP settings for sending emails.

Step 3: Configure the email settings

In the mailSettings section, you can specify the following settings:

• from: The email address that will be used as the sender.
• smtp: The SMTP server settings, including the host, port, and authentication settings.

For example:

<mailSettings>
  <smtp from="[email protected]">
    <network host="smtp.example.com" port="587" userName="your-username" password="your-password" />
  </smtp>
</mailSettings>

Step 4: Configure the error log settings

In the elmah section, you can specify the following settings:

• errorLog: The type of error log to use (in this case, Elmah.ErrorLog).
• logType: The type of log to generate (in this case, ErrorLog).

For example:

<elmah>
  <errorLog type="Elmah.ErrorLog, Elmah" />
  <logType>errorLog</logType>
</elmah>

Step 5: Test the email log

To test the email log, you can simulate an error in your application by throwing an exception. For example:

throw new Exception("Test error");

ELMAH should send an email to the specified email address with the error log details.

Tips and Variations

• You can customize the email subject and body by modifying the elmah.errorMail section in your web.config file.
• You can also use a custom email template by specifying the template attribute in the elmah.errorMail section.
• If you're using a cloud-based SMTP service, you may need to configure the mailSettings section accordingly.
• You can also use other error log handlers, such as the Elmah.SqlErrorLog class, which logs errors to a database instead of sending emails.
