Take a look at http://community.landesk.com/support/thread/4028?tstart=0
For memory you can set a treshold for all servers, for CPU this is removed in LD ServerManager 8.8
Already asked for a CR on this functionality. Also it is not possible to see a history of the CPU/Memory usage, this should be a basic feature if you want to monitor servers.
Take a look at the documentation for Monitoring and Alerting how to set things up.
Thanks for that
For now I just logged into each server and set the monitoring up for it and it works well.
