  7. IT Data Center Management • The Problem • How to manage and monitor a Linux based enterprise class corporate IT data center and networks given the mission critical requirements • Traditional solution • Use a proprietary commercial solution • Today’s alternative • Convert to Open Source management solutions

  8. Commercial ToolsSolutions • Leading commercial proprietary solutions • IBM Tivoli • HP OPenView • BMC • CA (Computer Associates) • Commercial solutions suffer from “functionality overkill” • Overload of features not required by most users

  9. Commercial ToolsDeployment • Deployment issues • Over-deployment -> “turn on everything” • All the functionality is not actually required • Requires additional staff to maintain • Frequently results in poorly tuned alarms and notification schemes • Under-deployment • Licensing fees are paid for unused functionality • Fees are recurring with annual licensing contracts

  10. Commercial ToolsCosts • Licensing Fees • Fees can approach 7 figures • Deployment and system administration can cost 5 times as much as initial licensing fee • Installation can take several months • Proprietary solutions require specialized programming skills • Companies must maintain deep expertise in proprietary software or hire pay high cost consulting fees to maintain and upgrade their environment

  11. Open Source ToolsCharacteristics • Standards based • Open interfaces • Modular and configurable • Built on component architectures • Designed to be easily modifiable • Code source is transparent • No licensing fee*

  12. Open Source ToolsAdvantages • Managing custom-built applications • Not suited for out-of-the-box solutions • Configuration required for specific parameters • Open interfaces make custom management a good fit • Easy integration • Open source solutions make good master IT managers • Easier integration of various monitoring and performance management systems

  13. Open Source ToolsAdd-in Functionality • Software enhancement • High probability that many needed add-in functions are available online in the open source community • Development uses open, standard protocols and API’s • Training personnel in standard API’s is a good long-term investment • There is a large pool of source developers (as opposed to proprietary specialists) available to hire or as contractors

  14. Open Source ToolsCollaborative Development • Bug Fixes • The greatest advantage of open source software is the global testing and peer review process controlled by the open source project • Source code is available for determining the root cause of the each bug • A world-wide network of IT professionals submit fixes and enhancements back to the project • Open source project leaders review and have the fix tested before releasing the fix back into open source

  15. Open Source ToolsLower Cost • Lower cost, both up front and long term TCO, is the key driver for Open Source IT monitoring and management • Low Acquisition Cost • Core software is free • Up front cost is for enhancements, services and support

  16. Open Source ToolsLower Cost • Lower Deployment Cost • Companies install only what they need • Deployments tend to be completed more quickly • Low system administration overhead • Installations are not burdened by gratuitous features • Vendor specific training is not required • Staffs become self-reliant over time

  17. Open Source ToolsLower Cost • Low scaling costs • Adding new resources (applications, servers, and networks) require new management system add-ons • Commercial products • Agents or SPIs involve more expenditures if they even exist • Or they may require development by the vender or a third party • Open source • No additional cost is incurred • Features are usually available from the open source community

  18. Leading Open Source IT Management Tools • Nagios • JFFNMS • OpenNMS • Big Sister • Netdisco • Zabbix • MRTG • Ntop • Syslog NG • RRDtool • Cacti • Nmap • NeDi • Cfegine • Nessus • Snort • Kismet • Webmin

  19. Leading Open Source IT Management Functions • Systems • Monitoring • Performance Graphing • Remote Security Scanning • Analytical Graphing • Network • Monitoring • Management • Traffic Monitoring • Traffic Analysis • Performance Graphing • Discovery • Inventorying • Configuration • Intrusion Detection • Wireless Detection

  20. Why are Companies moving to Open Source • Merger or Acquisition • Simpler low cost solution required • Newly merged IT resources • New CIO Committed to Open Source • New management understands the advantages of open source • Corporate Mandate to Lower IT Costs • IT operations face severe spending reductions • Corporate Mandate for Open Source Software • Company policy adopts an open source software policy • Governments mandate exclusive use of open source software

  21. How to Create an Open Source Management Solution • The Open Source community provides the pieces… • The solution must be integrated by • A solution supplier • Your IT organization • Third party consultants

  22. Example – IT Management Solution Supplier • Groundwork creates a totally integrated IT infrastructure monitoring and management solution using open source components • Core components from Nagios and MySQL • PHP portal based web interface • Management level reporting • Configuration tools • Monitoring tools

  23. Groundwork Monitor WEB PORTAL UI UI EXTENSIONS INTEGRATED CONSOLE PERFORMANCE AND AVAILABILITY REPORTS MONITORING AND CONFIGURATION PORTAL FRAMEWORK (Guava) GROUNDWORK FOUNDATION APPLICATION PROGRAMMING INTERFACES (APIs) COMMON DATA MODEL DATABASE (MySQL) ADAPTERS OPEN SOURCE TOOLS 3rd PARTY SYSTEMS PERFORMANCE MONITORING RRDtool NETWORK SYSTEMS APPLICATION MGT CONFIGURATION MGT SERVICE DESK AVAILABILITY MONITORING Nagios SNMP TRAPS SNMP TT ALARM PROCESSING Nagios SYSTEM LOGS Syslog NG OTHER DEVICES NETWORKS SERVERS DATABASES APPLICATIONS

  24. Open Management Consortium

  25. Open Management Consortium • May 9, 2006 - Six Leading open source systems and network management vendors formed the OMC • Nagios Ayamon • NetDirector Emu Software • openQRM Qlusters • openSIMS Symbiot • Webmin Zenoss • Zenoss Zenoss

  26. Nagios • Nagios is a host and service monitor designed to manage and track network and host resources • Works well with Linux and most *NIX operating systems • A Monitoring daemon runs intermittent checks on hosts and services • uses external plugins which return status information

  27. Nagios • Monitors • Host resources • processor load, disk and memory usage, running processes, log files… • Network services • SMTP, POP3, HTTP, NNTP, PING… • Environmental factors • Temperature, humidity… • Plug-in design allows development of custom host and service checks • Able to design custom event handlers • Web interface for remote viewing of status and problems

  28. NetDirector • NetDirector is framework for managing configurations of common open source network services. • Works well with Linux and most *NIX operating systems • Network Configuration changes for single or multiple servers • Can be immediate or scheduled

  29. NetDirector Manages the following • HTTP (Apache) • DNS (BIND) • DHCP • File and Print Services (Samba, NFS) • Email (Postfix, Sendmail) • FTP (VSFTP) • Users and Groups (mass add users to multiple servers at once) • Network Interfaces Other Features • Rollbacks (Revision Control) Troubleshooting/Logs • Schedule Changes • Server configuration cloning • Intuitive integrated support for managing clustered servers and disaster recovery configurations • Track Past or Scheduled Changes to be done • Track who made what changes and when

  30. openQRM • openQRM is a data center management platform with the following features • Data Center Management • Manages thousands of servers • Generates custome reports • Automatic, policy based provisioning • Maintenance Tasks • Extensible with plug-ins

  31. Zenoss • Zenoss is composed of several different open source components • Current version is monitor focused • Future versions will develop deeper “management” functionality

  32. openSIMS • openSIMS - Open Source Security Infrastructure Management System • OpenSIMS provides a way for tying together the open source tools used for security management into a common infrastructure. It leads toward having different networks use risk metrics to collaborate on attacker profiling and remediation. • Current version is 0.9 – still in beta

  33. Summary • Open Source has proved to be a viable source for enterprise class software • IT Management Software is entering the mature stage of Open Source development • Total Cost of Ownership for IT Management Software can be significantly reduced by transitioning a data center’s infrastructure to Open Source
