Hm, I'm afraid that this can't be realized with the built in sensors. Do the entries have a timestamp field we could use for calculations?

Would you like to trigger a action within your SQL database? If not, what exactly do you mean with alarm (without notification)? That somehow contradicts... :/

Are you already monitoring login/logout within PRTG? If so, what sensor are you using?

Well that won't do any good in terms of monitoring log in/out operations within a SQL database as ping only checks the availability of the host to respond to a ping. You basically need to get the number of concurrent user sessions with a query and use one of our SQL sensors to retrieve that value. Then you can use the channel limits to alert accordingly, once no logins happen within a certain timespan.

More information about the SQL sensors can be found here: https://www.paessler.com/manuals/prtg/available_sensor_types#database

The text mail content can actually be changed, directly in the notification settings, when the format is set to " Text with custom content". However, there's no placeholder that represents a link to the current live graph unfortunately. The same goes for values. Only the latest value can be inserted using %lastvalue.
