Slides of my talk about how openATTIC implements storage monitoring at the Monitoring Workshop 2016 in Kiel, Germany

1. Storage Monitoring in openATTIC
Monitoring Workshop 2016, Kiel, Germany

2. 2
openATTIC – Our Vision
 Develop an open source alternative to proprietary
storage management systems
 „Traditional” unified storage (NAS/SAN)
 Support Ceph for scale-out scenarios
 Backed with commercial support and services

3. 3
openATTIC – Notable Recent Changes
 Removed Enterprise/Community Edition split
 Now fully under the GPLv2
 Removed requirement for CLA
 DCA (Signed-off-by) is all that's needed
 Public Jira Bug Tracker (Issue tracking & roadmap)
 Public pull requests / code reviews on BitBucket
 Development/Release Branch
 Monthly releases / nighly snapshot builds
 Entire code base (Backend/WebUI/Test/Docs) in one branch

4. 4
openATTIC – What Sets us Apart?
 Focus on data center storage management
 Support both SAN and NAS functionality without limitations
 Fully Open Source (GPLv2)
 No arbitrary functional restrictions
 Low entrance barrier for adoption
 Based on Linux / OSS tools
 Multiple Linux distributions (Debian/Ubuntu/Red Hat/SUSE)
 Well-established technology stack (e.g. drivers, hardware support)
 Broad user base

5. 5
 Modern Web UI
 RESTful API (Software-
Defined Storage)
 Unified Storage
 NAS (NFS, CIFS, HTTP)
 SAN (iSCSI, Fibre Channel)
 LVM, XFS, ZFS, Btrfs,
ext3/4
 Volume mirroring (DRBD®)
 Multi-node support
 Monitoring (Nagios/Icinga)
built-in
 Ceph management and
monitoring (WIP)
 Development sponsored
by it-novum
openATTIC – Open Source Storage Management

6. 6
 Backend
 Python (Django)
 Django REST Framework
(RESTful API)
 Linux tools for storage
management, e.g. LVM, LIO,
filesystem utilities, DRBD,
etc.
 Nagios/Icinga &
PNP4Nagios (Monitoring
and Graphing)
 Web Frontend
 AngularJS (JS framework)
 Bootstrap (HTML, CSS, and
JS framework)
 Uses REST API exclusively
 Automated Test Suites
 Python Unit Tests
 REST Backend Tests
(Gatling)
 WebUI Tests
(Protractor/Jasmine)

openATTIC – Remote Ceph Node Monitoring
 Deploy collectd on each remote node via Salt
 Transmit data to oA node using collectd network plugin
 Write data using collectd RRDTool/RRDCacheD plugin
 Question: is this feasible? Any better alternatives?
