ScyllaDB extends warm holiday wishes and a Happy New Year to its audience, expressing hopes for quick query responses with their General Availability (GA) release imminent. The blog post suggests readers explore content on monitoring ScyllaDB during the holiday season.

ScyllaDB version 0.13, released on December 15, 2015, is a Cassandra-compatible NoSQL database known for its high performance and consistent low latency. This release is part of the beta series, focusing on stability and bug fixes, and introduces new features such as supported procedures for adding and removing nodes using commands like nodetool decommission and nodetool removenode, along with additional nodetool operations. The release also includes an update to the latest versions of seastar and scylla-jmx, with further details on contributions and known issues available on the ScyllaDB wiki. The version is accessible as a binary distribution or through Amazon EC2 AMI, with a general availability release scheduled for January 2016. Users are encouraged to follow ScyllaDB on Twitter or subscribe to their RSS feed for updates on future releases.

ScyllaDB can be effectively monitored using a combination of collectd, riemann-dash, and Tessera, with data visualization facilitated by Docker containers. These tools allow ScyllaDB to send performance data every second, enabling real-time monitoring of a cluster's performance through a simplified setup process. The necessary monitoring components, including Riemann, Tessera, and Graphite, are packaged in Docker containers, and once the ports are configured and the Docker images are pulled, users can access dashboards to view system measurements. For remote monitoring on Amazon AWS, the process involves setting up security groups with open ports, installing Docker and Git, and using scripts such as start-all-ec2.sh to configure the system. Additionally, a pre-built AWS AMI is available for easier deployment. Users are encouraged to utilize a single collectd server for the entire ScyllaDB cluster, and further configuration and customization are possible through the scylla-monitoring repository and related tools.
