At the November DOXLON, Facebook gave us an in-depth look into the way we have managed containers over the past 8 years, and why a complete overhaul is coming, with an entirely new control group system. Epam Systems showed us how to use the ELK stack together with Beats Plugin data shippers for system metrics, along with monitoring multiple Docker containers. Neil Chowdhury at Strft focused on how they are using Splunk and data models for collaboration, and the need for semantic logging.
We've started to use a new time-series database called Dalmatiner DB which relies on the filesystem for features like compression and consistency checking. Initially this database was written for SmartOS which has native ZFS support but given the maturity of ZFS on Linux we thought we'd run our setup on Linux.
