Access the metric values through macros

To simplify the access to some specific values defined inside the SeD , you can use these macros:
-
TOTALTIME(SeD)
-
COMMTIME(SeD)
-
TCOMP(SeD)
-
TIMESINCELASTSOLVE(SeD)
-
COMMPROXIMITY(SeD)
-
TRANSFEREFFORT(SeD)
-
FREECPU(SeD)
-
FREEMEM(SeD)
-
NBCPU(SeD)
-
CPUSPEED(SeD, idx)
-
TOTALMEM(SeD)
-
AVGFREEMEM(SeD)
-
AVGFREECPU(SeD)
-
BOGOMIPS(SeD, idx)
-
CACHECPU(SeD, idx)
-
TOTALSIZEDISK(SeD)
-
FREESIZEDISK(SeD)
-
DISKACCESSREAD(SeD)
-
DISKACCESSWRITE(SeD)
-
USERDEFINED(SeD, idx)
The macros taking two arguments need an index to choose which CPU measurement is needed. Two extra macros are defined:

Here is an example of an aggregate function using these macros:

SORTFUN(compBogo, BOGOMIPS)

int MyScheduler::aggregate(corba_response_t* aggrResp, size_t max_srv,
                           const size_t nb_responses,
                           const corba_response_t* responses)
{
  ServerList candidates = CORBA_to_STL(responses, nb_responses);
  ServerList chosen;
  ServerList::iterator it;

  for (it=candidates.begin(); it!=candidates.end(); ++it)
    if (NBCPU(*it)>=2) chosen.push_back(*it);
  SORT(chosen, compBogo);

  STL_to_CORBA(chosen, aggrResp);
  return 0;
}
This aggregation method first selects only the SeD which have more than 1 CPU and sorts them according to their number of Bogomips.
