How can I set an alert with firing setted to send an email to me.
But when It fires on the mail it has to show me a dashboard previous created is it possible?
otherwise in the mail alert has to show me the result of it. In this case how the searching needs to be setted?
here is link to documentation how to create alerts.
With alerts there are basically reports/search which you can use. If you want to send dashboard it's not alert but scheduled send dashboard. There are some restrictions what you could have in dashboard when you want send it with schedule.
