4. 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

5. 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
