Infrastructure Monitoring/ Issue Tracking
  • Monitor
    • PCU (demo) , Nodes (demo) , Sites (demo)
    • Reinventing monitoring infrastructure
  • Nagios
    • Nodes/Sites (demo)
    • Inflexible interface for taking actions, exposing web
  • OpenView
    • Unknown
runtime monitoring
Runtime Monitoring
  • CoMon
    • Node and Slice level monitoring
    • Instantaneous statistics over time
  • Chopstix
    • Kernel extension & module in PlanetLab 4.2 kernel
    • Given an systemic observation, narrow scope:
      •  to slice      to application     line of code
traffic monitoring
Traffic Monitoring
  • PlanetFlow - Associate packets with slices
  • 4.2 Implementation
    • Prevent data loss
    • Use existing \'netflow\' format for data
    • Central collection / query interface
    • Much faster
