git:andrei/counters: kcore stats: rewrote in terms of the counters api

The only important usage difference is that sr counters are uniquely identified by group and name (one can have counters with the same name if they are in different groups), while kamailio stats vars had unique names. This means that when using the kamailio get_stat(name) the first counter matching that name will be returned (in the future this kind of usage should be obsoleted). Removed functions (not needed): get_stats_collector() destroy_stats_collector() Removed data types: stats_collector module_stats New functions: stats_support() - partially replaces get_stats_collector(). get_stat_name() - returns the name of a stat_var. get_stat_module() - returns the module of a stat_var. --- lib/kcore/kstats_wrapper.c | 105 ++++++++++++++++++ lib/kcore/kstats_wrapper.h | 171 ++++++++++++++++++++++++++++++ lib/kcore/statistics.c | 251 +------------------------------------------- lib/kcore/statistics.h | 104 +------------------ 4 files changed, 279 insertions(+), 352 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=efb…

git:andrei/counters: sercmd: fix cfg. var name completion

git:andrei/counters: core: counters / statistics support

by Andrei Pelinescu-Onciul

Module: sip-router Branch: andrei/counters Commit: 4208dc00cf245559ed3152beace6084c7c6c4571 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=4208dc0… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Sun Aug 8 18:41:30 2010 +0200 core: counters / statistics support Efficient counters support (api). Incrementing or adding a value to a defined counter is extremely fast at the cost of slower reading (each process has its own set of counters => no cacheline ping-pong and no expensive atomic operations). All counters must be defined before forking (in a module this means from mod_init() or init_child(rank==PROC_INIT)). A counter is uniquely identified by its group and its name (and not only by its name like in kamailio stats). Example (error checking skipped): /* before forking, e.g. mod_init() */ counter_handle_t h; /* declare the counter my_grp.foo */ counter_register(&h, "my_grp", "foo", 0, 0, 0, 0); /* after forking */ counter_inc(h); /* getting a counter value, knowing its group and name*/ counter_lookup(&h, "my_grp", "foo"); val = counter_get(h); --- counters.c | 696 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ counters.h | 124 +++++++++++ main.c | 10 +- 3 files changed, 828 insertions(+), 2 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=420…
