Task 1
Every time I add a SQL server, I set up the
same set of services, processes, and
application monitors. How do I automate this
in OpManager?
I have grouped all MSSQL Servers in a
'Business view' for our Riyadh site, and more
servers will be added in the future. Can I place
these servers in the Riyadh group
automatically?
I've set up a notification profile to trigger an
email notification for service down alarms. Can I
assign this notification profile automatically
when a server is added to OpManager?
