LHASH statistics
SYNOPSIS
#include
<openssl/lhash.h>
void
lh_stats(LHASH *table,
FILE *out);
void
lh_node_stats(LHASH *table,
FILE *out);
void
lh_node_usage_stats(LHASH
*table, FILE *out);
void
lh_stats_bio(LHASH *table,
BIO *out);
void
lh_node_stats_bio(LHASH *table,
BIO *out);
void
lh_node_usage_stats_bio(LHASH
*table, BIO *out);
DESCRIPTION
The LHASH structure records statistics about most aspects of accessing the hash table.lh_stats()
prints out statistics on the size of the hash table, how many entries are in
it, and the number and result of calls to the routines in this library.
lh_node_stats()
prints the number of entries for each 'bucket' in the hash table.
lh_node_usage_stats()
prints out a short summary of the state of the hash table. It prints the
'load' and the 'actual load'. The load is the average number of data items
per 'bucket' in the hash table. The 'actual load' is the average number of
items per 'bucket', but only for buckets which contain entries. So the
'actual load' is the average number of searches that will need to find an
item in the hash table, while the 'load' is the average number that will be
done to record a miss.
lh_stats_bio(),
lh_node_stats_bio(),
and
lh_node_usage_stats_bio()
are the same as the above, except that the output goes to a
BIO.
