During the process user can input the threshold# limit or the interval through the following commands:# THR - Input of threshold# INTR - Interval at which the TCL script has to do checking.# To quit out of the script type QUIT and hit enter#Default threshold is 2 %set thr 2#Default interval is 10 secondsset intr 10#change this mail id to your ownset mailid "mailto://xyz@xyz.com"#initalize eventsproc initEvents { } {global mailid#add subscriptions to events.ampaddsubscription event.alarm.cpu $mailid#save subscriptionampsave}#delete events.
