rrdtool tune --heartbeat can change minimal_heartbeat from 600
(default, used for 300s intervals) to 900 or higher. Ideally, the
value should be identical to the LIFETIME value (if you're sending
"status color+LIFETIME", try "man bb"), as it serves the same purpose
as going purple: marking intervals of stale values as unknown. But
there's a history of LIFETIME defaulting to 1800 seconds...
