Accounting probes can collect three types of data:
- Per-lease data
- : Data attributable to individual leases or derived from how each lease was scheduled. For example, as mentioned earlier, the best-effort probe collects the waiting time of each best-effort lease.
- Per-run data
- : Data from a single run of Haizea. For example, the ar probe collects the total number of AR leases that were accepted and rejected during the entire run.
- : A counter is a time-ordered list showing how some metric varied throughout a single run of Haizea. For example, the best-effort probe keeps track of the length of the queue.
See Appendix ) for a list of probes included with Haizea, and a description of the specific data they collect.
