The period of time that the condition defined in the alarm must persist before the alarm state
changes from "OK" to "FIRING" or vice versa. For example, a value of 5 minutes means that the
alarm must persist in breaching the condition for five minutes before the alarm updates its
state to "FIRING"; likewise, the alarm must persist in not breaching the condition for five
minutes before the alarm updates its state to "OK."
The duration is specified as a string in ISO 8601 format ({@code PT10M} for ten minutes or {@code PT1H}
for one hour). Minimum: PT3M. Maximum: PT1H. Default: PT3M.
