Zenoss presentation (nur nabilah hassan)

  2. 2. ABOUT ZENOSS CORE … • Zenoss (Zenoss Core) is a free and open-source application, server, and network management platform based on the Zope application server. • Released under the GNU General Public License (GPL) version 2. • Provides a web interface that allows system administrators to monitor availability, inventory/configuration, performance, and events. * Zope Application server: An object-oriented web server written in Python.
  3. 3. ZENOSS CORE PROVIDES : • Monitoring availability of network devices using SNMP, SSH, WMI • Monitoring of network services (HTTP, POP3, NNTP, SNMP, FTP) • Monitoring of host resources (processor, disk usage) on most network operating systems. • Time-series performance monitoring of devices
  4. 4. ZENOSS MAJOR PARTS : • User Layer (Web Portal) • Watch the status of your enterprise, using the Dashboard • Work with devices, networks, and systems • Monitor and respond to events • Manage users • Create and run reports *The user layer Interacts with the data layer and translates the information for display in the user interface.
  5. 5. ZENOSS MAJOR PARTS : • Data Layer • Configuration and collection information is stored in the data layer, in three separate databases: • ZenRRD- Utilizing RRDtool, stores time-series performance data. Because RRD files are stored locally to each collector, no bottlenecks result from writing to a single database as new collectors are added. • ZenModel- Serves as the core configuration model, which comprises devices, their components, groups, and locations. It holds device data in the ZEO back-end object database. • ZenEvents- Stores event data in a MySQL database
  6. 6. • Process Layer • manages communications between the collection and data layers • utilizes Twisted PB (a bidirectional RPC system) for communications. • Collection Layer • comprises services that collect and feed data to the data layer • Provided numerous daemons that perform modeling, monitoring, and event management functions.
  7. 7. ADVANTAGES : • Open Source • Free and open source • Backed by the efforts of a large community of users • Deploy and adapt on your own terms • Full Lifecycle Visibility • Monitor performance and availability • Centralize fault/alarm/event management • Real-time alerting & reporting • Physical and Virtual IT Infrastructure • Single integrated view of networks, servers and apps • Seem less visibility between virtual and physical machines • Cross-vendor, cross-platform support (Windows, Linux, Unix)
  8. 8. • Scalable for the Enterprise • Auto-discovery and policy-driven configuration makes it easy to configure in large environments • Management tools for large, distributed configurations • High availability • Open, Flexible Architecture • Open architecture makes it easy to customize and extend • Open standards and agentless deployment eliminate lock-in • Affordable • Use what you like for free
  9. 9. ANNOYANCES : • Web interface feels slow (Zope is bloated) • Limited open-source version. Full version needs to be paid for. • Performance • SELECT operation in MYSQL Database produces extra high I/O when getting some data from the Events History. • Complexity • requires a bit more than a superficial knowledge of the interface • Opaque operation • You can add monitoring and check back later if anything worked they way you want.
  10. 10. • Configuration and data is spread across MySQL, the internal Zope database storage and RRD files on disk.
