  9. How to Monitor? 單一主機の監控 分散式監控系統 2010/6/8 NCNU CSIE Stella 9

  10. How to Monitor? 單一主機の監控 commands : top, free, uptime, ps Log file Shell scripts MRTG ...etc.分散式監控系統 2010/6/8 NCNU CSIE Stella 10

  11. How to Monitor? 分散式監控系統 Network utilization CPU utilization Hardware System load Disk utilization ...etc. 2010/6/8 NCNU CSIE Stella 11

  12. Ganglia? Nagios ←→ Ganglia graph display → easy to see show host metrics visualize trends 2010/6/8 NCNU CSIE Stella 12

  13. WHAT? 2010/6/8 NCNU CSIE Stella 13

  14. WHAT IS GANGLIA ? 2010/6/8 NCNU CSIE Stella 14

  15. Ganglia - Wiki 2010/6/8 NCNU CSIE Stella 15

  16. Ganglia distributed monitoring system monitor tool for clusters and grids view live or historical statistics CPU load averages network utilization long-term trends graph display 2010/6/8 NCNU CSIE Stella 16

  17. WHAT IS Distributed System ? 2010/6/8 NCNU CSIE Stella 17

  18. Distributed Monitoring System Components : daemons that reside on cluster nodes server that collects clusters state information from nodes GUI-based front-end, which provides system activity visulization as for Ganglia components : → gmond → gmetad → web front-end 2010/6/8 NCNU CSIE Stella 18

  19. Ganglia Architecture 2010/6/8 NCNU CSIE Stella 19

  20. gmond Ganglia monitoring daemon Multithreaded Responsibilities : Monitor changes in host states Announce relevant changes Listen to the state of all the other ganglia nodes via a unicast or multicast channel Answer requests for an XML description of the cluster state. 2010/6/8 NCNU CSIE Stella 20

  21. gmetad Ganglia meta daemon Aggregate data, information steps : Poll gmond, clusters, or other gmetad Parse the collected XML Save numeric metrics in RRD(round-robin database) Export aggregated XML over TCP to clients 2010/6/8 NCNU CSIE Stella 21

  22. web front-end web interface written in PHP Graph generated by gmetad displays historical information highly dynamic 2010/6/8 NCNU CSIE Stella 22

  23. monitor interaction Gmond runs on each cluster node; gmetad can fail over between nodes. 2010/6/8 NCNU CSIE Stella 23
