On the command line:
REDIS_NAMESPACE='logstash:app:unmappable' REDIS_URL='redis://redis-internal:6379/0' beaver -f /apps/production/current/log/unmappable.log -t redis
My logstash input:
redis {
host => 'redis-internal' # this is in dns for work
data_type => 'list'

Operation: Decouple whisper from graphite.
Method: Create a graphite function that does a date histogram facet query against elasticsearch for a given query string for the time period viewed in the current graph.
Reason: graphite has some awesome math functions. Wouldn't it be cool if we could use those on logstash results?
The screenshot below is using logstash to watch the twitter stream of keywords "iphone" "apple" and "samsung" - then I graph them each, so we get an idea of popularity. As a bonus, I also do a movingAverage() on the iphone curve to show you why this is awesome.
