OK, So I have chosen 10 IIS Current Connection (SNMP) sensors from 10 servers (via the All Sensors list). I go to edit them using MultiEdit to add a notification to all of them. I cant - Notifications are not an option in there to edit ? ???
So either :
1.) We make sure we build the initial template absolutely correctly and never want to change it, or
2.) When (inevitably) we decide to monitor an extra senor or add a new notification type we have to do it :
a) manually per sensor across multiple servers, or,
b) create new device template, Pause Indefinitely or Delete the old Devices and Re-Discover them using the new Template.
(1) above is not going to happen ever in a real production environment
(2)-a is not ideal as we end up with loads of "dead" devices that we are keeping purely for historical data purposes
(2)-b is not ideal either. Any Sensor Factory sensors will need to be edited as well as a re-discovery of a device will end up with new Sensor IDs.
Surely this is something that needs to be worked on more ? Production Environments need to be able to mass-add / edit sensors, notifications etc. PRTG provide a great idea in Device Templates but then limit it too much. I understand that you want to protect users from themselves in doing device -rediscoveries, but surely an override option can be added to allow a device be re-discovered against a new template (or modified one) to add sensors/notifications etc. Stick big warnings on that options to tell people that they could end up with stuff they didn't expect - but at least give us the option !
I don't know if this is a show stopper for us. Competing products do this already (NAGIOS Ops View). It may not stop us buying PRTG but it is not helping ! :)
