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
