Is it possible? - feature request

I'm just new in testing Opmanager

Is it possible to read Operating systems environment variables from remote servers?

I would like to create scripts that do some tasks and the result is stored in a variable - e.g. count the number/size of files in a directory - the variable could then be read from Opmanager. (Stored in DB for graphs)

Is it possible to create notifications according to working hours
Example during 7am to 5pm notify Helpdesk by e-mail - during night notify by SMS to someone else?

Is it possible to start scripts/programs on the client (monitored server) according to events received from the OpManager Server.

Is it possible to extend the device categories (Server,Desktop,Switch,DC etc.)
Can i create groups of monitored devices -
I would like to have a group of devices that are needed for one application to run
(Switch,Server etc. in one view) - best would be if i can call it for example (Backup Infrastructure, Fileservices)

Is it possible to have a view only login that works without a password
(direct intranet links from our server database to the device - without login)
