Function Documentation

◆ conn_stats_format()

char * conn_stats_format ( time_t  now)

Return a newly allocated string containing the connection statistics until now, or NULL if we're not collecting conn stats. Caller must ensure start_of_conn_stats_interval is in the past.

Definition at line 224 of file connstats.c.

◆ conn_stats_free_all()

void conn_stats_free_all ( void  )

Release all storage held in connstats.c

Definition at line 112 of file connstats.c.

◆ conn_stats_init()

void conn_stats_init ( time_t  now)

Initialize connection stats.

Definition at line 30 of file connstats.c.

◆ conn_stats_note_or_conn_bytes()

void conn_stats_note_or_conn_bytes ( uint64_t  conn_id,
size_t  num_read,
size_t  num_written,
time_t  when,
bool  is_ipv6 

We read num_read bytes and wrote num_written from/to OR connection conn_id in second when. If this is the first observation in a new interval, sum up the last observations. Add bytes for this connection.

◆ conn_stats_reset()

void conn_stats_reset ( time_t  now)

Reset counters for conn statistics.

Referenced by conn_stats_terminate().

◆ conn_stats_save()

time_t conn_stats_save ( time_t  now)

If 24 hours have passed since the beginning of the current conn stats period, write conn stats to $DATADIR/stats/conn-stats (possibly overwriting an existing file) and reset counters. Return when we would next want to write conn stats or 0 if we never want to write.

Definition at line 260 of file connstats.c.

◆ conn_stats_terminate()

void conn_stats_terminate ( void  )

Stop collecting connection stats in a way that we can re-start doing so in conn_stats_init().
