Can be used in crontab like this:

SHELL=/bin/bash
BASH_ENV=~/.bash_profile
# m h  dom mon dow   command
0    * * * * /home/portfolio/portfolio/bin/session.pl                2> >(json-logger -ep pf_session)                | json-logger -p pf_session
0    2 * * * /home/portfolio/portfolio/bin/purge_deleted_messages.pl 2> >(json-logger -ep pf_purge_deleted_messages) | json-logger -p pf_purge_deleted_messages
0,30 * * * * /home/portfolio/portfolio/bin/expire_page_views.pl      2> >(json-logger -ep pf_expire_page_views)      | json-logger -p pf_expire_page_views

I would suggest you put it in /usr/bin to avoid having to setup your PATH variable.

logstash queries graphed with graphite.

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.
