Introduction:
I have a host that will be permanently offline and I need to monitor it for connection. I want the alert to be generated if the host comes online. Not if its down, but if it comes up.
Instructions:
One possible solution is to use the ICMP probe. 

To do so configure a profile as follows:
  • Configuring the probe using the Admin Console create a profile for the server
  • Select the ServiceAvailability metric (if any packet in the ping comes back 100% is reported so greater than 0 should alarm that the device is up)
    • Publish QOS
    • Publish Alarms

ICMP - ServiceAvailibility - Publish QoS and Alarm
  • Set a static alarm threshold > 0
  • Set a Custom Alarm Message(example):
Server ${target} is now Alive!!
 
ICMP - ServiceAvailibility - Static Threshold and Custom Alarm Message
