end

#in_state(status) ⇒ Object

How many alerts are in the given state? If none, say so, rather than just printing nothing.

  options[:all] = true

  ok_exit(format('No alerts are currently %s.', status)) if ret.empty?
  ret
end

#state_time(item) ⇒ Integer

Snoozed alerts don’t have a start time, they have a “snoozed” time. This is -1 if they are snoozed forever: the formatting methods know what to do with that.

Returns:

  • (Integer)
