Field Documentation

uint64_t bw_array_t::obs[NUM_SECS_ROLLING_MEASURE]

Observation array: Total number of bytes transferred in each of the last NUM_SECS_ROLLING_MEASURE seconds. This is used as a circular array.

Referenced by add_obs(), advance_obs(), and rep_hist_load_state().

int bw_array_t::cur_obs_idx

Current position in obs.

Referenced by add_obs(), and advance_obs().

time_t bw_array_t::cur_obs_time

Time represented in obs[cur_obs_idx]

Referenced by add_obs(), advance_obs(), bw_array_new(), and rep_hist_load_state().

uint64_t bw_array_t::total_obs

Total for all members of obs except obs[cur_obs_idx]

Referenced by advance_obs(), and rep_hist_load_state().

uint64_t bw_array_t::max_total

Largest value that total_obs has taken on in the current period.

Referenced by advance_obs(), commit_max(), and rep_hist_load_state().

uint64_t bw_array_t::total_in_period

Total bytes transferred in the current period.

Referenced by add_obs(), commit_max(), and rep_hist_update_state().

time_t bw_array_t::next_period

When does the next period begin?

Referenced by advance_obs(), bw_array_new(), commit_max(), rep_hist_get_bandwidth_lines(), rep_hist_load_state(), and rep_hist_update_state().

int bw_array_t::next_max_idx

Where in 'maxima' should the maximum bandwidth usage for the current period be stored?

Referenced by commit_max(), and rep_hist_fill_bandwidth_history().

int bw_array_t::num_maxes_set

How many values in maxima/totals have been set ever?

Referenced by commit_max(), and rep_hist_fill_bandwidth_history().

uint64_t bw_array_t::maxima[NUM_TOTALS]

Circular array of the maximum bandwidth-per-NUM_SECS_ROLLING_MEASURE usage for the last NUM_TOTALS periods

Referenced by commit_max(), find_largest_max(), and rep_hist_load_state().

uint64_t bw_array_t::totals[NUM_TOTALS]

Circular array of the total bandwidth usage for the last NUM_TOTALS periods

Referenced by commit_max(), and rep_hist_fill_bandwidth_history().
