10. 10
openATTIC – Ceph Management Challenges
─Managing and monitoring Ceph is complex
─Many tools exist (e.g. Calamari, Intel VSM, ceph-dash)
─Limited functionality, unclear roadmaps
─Finding the best approach for managing Ceph

11. 11
openATTIC – Ceph Management Goals
─Create a management & monitoring GUI tool
─A tool that administrators actually want to use
─That scales without becoming overwhelming
─Still should allow changes to be made elsewhere, without
becoming inconsistent

12. 12
openATTIC – Ceph Management Implementation
─Which Ceph Management API?
─How to manage a distributed system?
─How to monitor the cluster‘s health/performance?
─How to perform remote management tasks?
─How to monitor cluster nodes in a scalable way?
