Call the matcher with the following sequence:
type = matcher
edgetrigger = yes
pattern = CheckLatency(l=>latency to check against,x=>num samples required for a match)
This will create a matcher which checks for l latency or greater over x samples before raising,
and will hold the alert until x samples under l before clearing
