Objectives of this series of articles:

- Save up to 90% disk space based on VRR (Variable Replication factor and Retention) estimations by playing with replication, retention and custom classification. Differentiate important from redundant information and apply different policies to them.

- Log useful information for once, that you will be able to filter, query, plot and alert on. We are covering parameters, structured arguments, and how to avoid grok to parse them.

- Save tons of OPS time by using the right tools to empower DEVs to be responsible of their logs. Let's avoid bothering our heroes with each change in a log line. Minimizing OPS time is paramount.

Seems promising, will read the whole bunch of posts and report
