Cnxcc doesn't update values in redis

[zenichev]

Description

Have a problem with cnxcc call monitoring.
__set_max_credit() allocates new call as expected:

"DEBUG: cnxcc [cnxcc_mod.c:444]: __dialog_created_callback(): Flag is not
set for this message. Ignoring
DEBUG: cnxcc [cnxcc_mod.c:1569]: __set_max_credit(): Setting up new call
for client [2], max-credit[0.100000], cost-per-sec[0.010000], initial-pulse
[6], final-pulse [6],
call-id[2f77fd103d0bfa28718d896876b373fe at b2b.user.agent:50600]
DEBUG: cnxcc [cnxcc_mod.c:1470]: set_ctrl_flag(): Flag set!
DEBUG: cnxcc [cnxcc_redis.c:313]: redis_get_int(): Got INT value:
concurrent_calls=0i
DEBUG: cnxcc [cnxcc_redis.c:68]: redis_get_or_create_credit_data():

DEBUG: cnxcc [cnxcc_redis.c:92]: redis_insert_credit_data(): Inserting

DEBUG: cnxcc [cnxcc_mod.c:1125]: __get_or_create_credit_data_entry():

DEBUG: cnxcc [cnxcc_mod.c:1255]: __alloc_new_call_by_money(): New call
allocated for client [2]".

So that I can see values inside redis:
redis.youwillnever.find:6389> HGETALL cnxcc:money:2
 1) "concurrent_calls"
 2) "0"
 3) "consumed_amount"
 4) "0.000000"
 5) "ended_calls_consumed_amount"
 6) "0.000000"
 7) "max_amount"
 8) "0.000000"
 9) "number_of_calls"
10) "1"
11) "type"
12) "1"


But cnxcc doesn't update credit amount during the call.


modparam("debugger", "mod_level", "cnxcc=4") but there are no rows in
kamailio log like:

"DEBUG: cnxcc [cnxcc_check.c:94]: check_calls_by_money(): ec=0.000000,
ca=0.600000, ca2=0.600000
DEBUG: cnxcc [cnxcc_check.c:107]: check_calls_by_money(): Client
[some_client] | Ended-Calls-Credit-Spent: 0.000000  TotalCredit/MaxCredit:
0.600000/3.000000".

cnxcc parameters:
modparam("cnxcc", "dlg_flag", FLG_DLG)
modparam("cnxcc", "redis", "addr=redis.youwillnever.find;port=6389;db=0")
modparam("cnxcc", "credit_check_period", 1)

function that performs credit setup:
if
(!cnxcc_set_max_credit("$var(setid)","$var(credit)","$var(cost_per_sec)","$var(i_pulse)","$var(f_pulse)"))
{
                xlog("L_WARN", "----- cnxcc: $fU - Error setting up credit
control - R=$ru ID=$ci\n");
                sl_send_reply("402", "Payment Required");
        }

Why is it so? And as see, all values are set zero. Seems to be problem with
redis inserts.
Any ideas are highly appreciated. Thanks.

Sorry for the delayed response.
Problem is solved by recompiling the cnxcc module.
