1 Open source integrated remote systems and network management with OpenRSM M. Kalochristianakis E. Varvarigos

2 Contents Systems and network management o Aims, technologies o State of the art and open source solutions The case of the Greek School Network o Need for Scalable, installable, usable solution o Challenges Current state of the market/art OpenRSM o Architecture and components o Open technologies o Pilot installations o Extensions

3 System and network management Automation in large scale o Organizing the infrastructure and procedures o Management framework and methods Management systems o High level (strategic)! components: systems, business units/processes/functions, architectural domains, infrastructure elements, etc! references: information flow, landscape, portfolio, masterplan, etc o Low level (applications)! errors, configurations, performance security et! SNMP, WBEM/CIM, WS-Management, SMASH, TMN, ASF, etc

4 The case of the School network 1/2 Benefits from integrated management o School labs management Fast resolution of problems, high response times o Central, systematic control Organization, reports and stats Services o Assets management o Remote desktop control o Software distribution o Network management

5 The case of the School network 2/2 EMS installation in 221 schools in 11 prefectures Problems o Organizational procedures could not sustain the project of scaled installation o Technical: low degree of automation, high complexity, insufficent installation procedure, low adaptation Solution: customisation o Size reduction, unattended procedures, custom installater options The next step: OpenRSM

6 OpenRSM Open source, integrated, mutilplatform management Integrated systems! Assets management and reporting! Remote command execution, job management! Software management! Network management! Extensions for wireless Funded by the National Information society Operational programme

7 Component architecture 1/2 Server o Control logic o Resource management o Informational systems Management console o Visual components and GUI o Integration of components Agent o Multiplatform o Conveys management commands

8 Component architecture 2/2

10 Functionality Assets management Remote control o Remote desktop o Std and reverse mode VNC o File transfer, messaging o Routing via the server o Client acknowledgements Command execution o o Random command support Command priority, visibility, type SNMP based network monitoring Network discovery Management console o Jobs prototyping and instantiation o Single job and batch mode execution o Static and dynamic groups for jobs and stations o Reports! Static / dynamic! Queries and stored queries! Exportable reports in various formats

11 Features Management for Linux/Windows o Different agents distributions o Common administrative consle Lightweight o Low memory, CUP, network and disk consumption o 72")*89 8"# #2*+*,9 ')38,*: High performance o Real time task exectution o ~150 ms/job o Scalable No prerequisites o Standard TCP/IP connectivity o Platform indepentent Security o Encrypted communication Custom communication protocos o UTP trigger, TCP handshake o Connections on demand o Support for active connections o Server locking

12 Stress and scale testing 22 jobs / sec, 35 msec / job 10 ;< max memory fluctuation Linear behaviour with respect to load

13 Pilot installations Achaia prefecture Public administration control service Central citizent's disposition bureau offices o ~38000 downloads (Sept 2010)

14 Future work Extensions o Management for embedded devices o Sensor management o Integration with EGEE Grid technologies Single click, unattended installation Web based console Migration to middleware o High level programming frameworks o Enterprise level technologies
