Monitoring Ceph clusters

Monitoring is the process of gathering, aggregating, and processing important quantifiable information about a given system. It enables us to understand the health of the system and its components and provides information necessary to take steps to troubleshoot problems that arise. A well-monitored system will let us know when something is broken or is about to break. Deploying a Ceph cluster involves an orchestration dance among hundreds, thousands, or even tens of thousands of interconnected components including variety of kernels, processes, storage drives, controllers (HBAs), network cards (NICs), chassis, switches, PSUs,and so on. Each of these components can fail or degrade in its own unique way.

External monitoring of a complex system is itself a significant endeavor and is best worked right into the architecture and deployment model. When monitoring is an afterthought (we'll get to it in phase 2) it tends to be less effective and less pervasively implemented...

D'Atri

Anthony D'Atri's career in system administration spans from laptops to vector supercomputers. He has brought his passion for fleet management and server components to bear on a holistic yet, detailed approach to deployment and operations. His experience with architecture, operation, and troubleshooting of NetApp, ZFS, SVM, and other storage systems dovetailed neatly into Ceph. Anthony worked for three years at Cisco using Ceph as a petabyte-scale object and block backend to multiple OpenStack clouds. Now helping deliver awesome storage to droplet customers of DigitalOcean, Anthony aims to help the growing community build success with Ceph.

Bhembre

Vaibhav Bhembre is a systems programmer working currently as a technical lead for cloud storage products at DigitalOcean. He holds a bachelor's degree in computer engineering from the University of Mumbai and a master's degree in computer science from the State University of New York in Buffalo. Before joining DigitalOcean, Vaibhav wore multiple hats and lead the backend engineering and reliability engineering teams at Sailthru Inc. From helping to scale dynamically generated campaign sends to over million users at a time, to architecting a cloud-scale compute and storage platform, Vaibhav has years of experience writing software across all layers of the stack. During his time as a student, Vaibhav co-published a novel graph algorithm that optimally computed closeness and betweenness in an incrementally updating social network. He also made changes to a highly available distributed file-system built on top of iRODs data management framework as his master's project. This system, that was actively used across more than 10+ educational institutions live, was his foray into large-scale distributed storage and his transition into using Ceph professionally was only natural.
