Detailed Description

Statistics collector implementation.

FIXME: This statistics collector was meant to be as generic as possible but it seems that it didn't live up to its promise. This is because the logic is based on the logic of the statistics collector used in the transaction statistics collector used by MTM. For the future, we would like to implement a more extensible statistics collector similar to the one used by Solaris kstat provider.

Define Documentation

#define RESETSTAT

(

name

)

Value:

statset->stats[m_stats_##name##_stat].total = 0;                    \
  statset->stats[m_stats_##name##_stat].min = 0xFFFFFFFF;             \
  statset->stats[m_stats_##name##_stat].max = 0;

Function Documentation

void m_stats_print

(

m_statsmgr_t *

statsmgr

)

Prints a statistics report.

Summarizes statistics and prints a report into the statistics file. Print the statistics report in the same format as the Intel STM's one to avoid duplicating post-processing scripts.

Parameters:

[in]

statsmgr

Pointer to the statistics manager collecting the statistics.

Returns:

None
