  • 1. Seminar On ZENOSS CORE (Network Monitoring Tool) Praful Bhosale MCA2 SEM –III KIT IMER’s MCA Dept. Date:-14-09-2013
  • 2. What is Zenoss Core?  Zenoss (Zenoss Core) is an open source application, server and network management platform based on the Zope application server. It's released under the GNU General Public License (GPL) version 2.  Zenoss Core provides a web interface that allows system administrators to monitor availability, inventory/ configuration, performance, and events
  • 3. Why Zenoss Core? Open Source Monitoring Solution More features including WMI performance monitoring Powerful plugins (ZenPacks)
  • 4. What Technologies used in Zenoss?  Zope :-Application server: An object-oriented web server written in Python. Python:-Extensible programming language. Net-SNMP-: Monitoring protocol that collects systems status information.  RRDtool:- Graph and log time series data.  MySQL:- A popular open source database. Twisted:- An event-driven networking engine written in Python.
  • 5. What Zenoss Core can do? 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 Extended Microsoft Windows monitoring via Windows Management Instrumentation using Zenoss open source extensions Event management tools to annotate system alerts Automatically discovers network resources and changes in network configuration Alerting system provides notifications based on rule sets and on-call calendars
  • 6. Zenoss Architecture
  • 7. Zenoss Architecture User layer Zenoss Core is flexible enough to work from a command line, but most of our work will take place via a web interface, which is based on the Zope application server framework. Zope is a popular, extensible application server written in Python. It features a built-in web server, transactional object database, and HTML templates. Python is the basis for Zope; it's also the basis for Zenoss Core.
  • 8. Zenoss Architecture Data layer RRD:- stores time series performance data CMDB:- managing the configuration, relationship, and change history of the IT environment, which creates a detailed model of the network
  • 9. Collection layer Zope Architecture The collection layer includes several daemons that gather information about devices, performance, and Events. They feed information to ZenHub to distribute to the appropriate database. The Zenoss Core daemons are easy to identify—they all start with the prefix "zen".
  • 10. Daemon It is a computer program that runs as a background process, rather than being under the direct control of an interactive user Device management daemons:- zenmodeler, zendisc. Performance and availability daemons:- zenperfsnmp,zencommand, Zenprocess,zenping,zenstatus. Event daemons:- Zensyslog,zeneventlog,zentrap.
  • 11. Zenoss Core Installation 1. visit 2. find native packages, stack installers, and source files for several operating systems:- Red Hat Enterprise Linux, Centos, Ubuntu, Fedora Core, OS X, OpenSuse, and Debian.,Windows. 3. Preparing devices for monitoring 4. Configuring SNMP and WMI 5. Configuring firewall
  • 12. Setting up users
  • 13. Specify or discover devices to monitor Adding devices
  • 14. Zenoss Dashboard
  • 15. Zenoss Event Console
  • 16. Zenoss Network Map
  • 17. Zenoss Performance & Reports
  • 18. Zenoss is a good choice for open source network and systems management. The Zenoss system provides full stack coverage of networks, servers, applications, services, and virtualization. Conclusions
