Now that your channel is using the VMD file to detect whether a duplicate message has been sent, the next step is to create an email notification rule that sends an email message if a duplicate message warning appears in the Iguana logs. To do this:

• Click the Settings tab at the top right of the screen. In the Settings screen, click E-mail Notification.

• Click the Notification Rules tab.

• In the Email Notification Rule screen, click Add a Rule.

• Select the Standard Rule radio button. A screen appears, enabling you to configure the email notification rule:

• From the Source Type list box, select Channel. The Channel list box appears.

• From the Channel list box, select the channel through which the messages are being sent.

• From the Type list box, select Informational.

• In the Text Query field, type "ALERT - DUPLICATE TRANSACTION OCCURRED" (including the quote characters).

• In the Limit of Messages Sent field, type 10 (or whatever limit you want to use).

• Select the Include Log Entry Text in Email Message check box. This will include the contents of the duplicate message warning in your email message.

• From the Recipients list box, select one or more users or groups that will receive notification email messages when a log message appears that matches the criteria defined in this rule.

The Edit Rule screen should now look something like this:

• Click Save Changes to create this rule. The rule now appears on the email notification rule page:

At this point, you have everything you need to detect whether a channel has received duplicate messages. The next section describes how you can test this email notification solution.
