The document discusses OpenAttic, an open-source storage management system focused on providing an alternative to proprietary solutions, fully compliant with GPLv2. It details recent developments, the architecture, installation processes on SUSE Linux, and future roadmaps for Ceph and storage pool management integration. Additionally, it highlights the challenges of managing Ceph and outlines goals for creating user-friendly management and monitoring tools.

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?
