Delay writing state to Zookeeper causes hosts to expire about satellite HOT 1 OPEN

Does the situation also improve if we move persisting to zookeeper to the
last position in the form? I think Riemann processes clauses in order.

When Zookeeper has latency in saving events, hosts will be added to the
blacklist due to their events timing out and being expired. Disabling the
persistence of events prevents this problem and allows hosts to appear on
the whitelist.

The way to diagnose this is to look at the time when an event is fully
processed compared to the time stored in the event. If this value is
greater than five minutes this problem will occur.

There should be a way to warn about this problem and detect it rather than
comparing the TTL of events manually with the time that they were processed.

Thank you,

Rusty
