To configure sending of emails from the application log you need component 6704 in your composition.
First of all you define your mail subscription via General Settings - Mail subscriptions
In my example I want to be informed about PrintNode errors
It is important that for you as a subscriber there is an email address defined in your connection information
Next step is to define one or more mail subscription data sources
Fill in the correct data source (that is used in the application log entries)
The from level and higher
The activity template
And the aggregate for number of hours
An example of the activity template to use
An example of the export definition
Another important setting is General settings - Mail subscription settings
In the mail subscription you can force sending of the e-mail by using the button ‘send mail now’
In the list of activities (Overviews - Activities) you can find your e-mail
And view the details sent by e-mail
