I changed this:
modparam("ndb_redis", "server", "name=srvN;addr=127.0.0.1;port=6379;db=1")
by it:
modparam("ndb_redis", "server", "name=srvN;addr=127.0.0.1;port=6379")

And began to work.

Thanks my friend !

Can you do the same with either reids on DB=1 or remove db=1 string from the ndb_redis url.

redis-cli
127.0.0.1:6379> select 1
127.0.0.1:6379[1]> GHET usuario:2001 status

OR

modparam("ndb_redis", "server", "name=srvN;addr=127.0.0.1;port=6379")

If that doesn't help I'll be happy to share the relevant configs which I assure you are the same.

Thanks,
Sammy

Thanks Sammy !

I tried that, but it's doesn't work.
Here below, both options:

redis-cli
127.0.0.1:6379> HGET usuario:2001 status
"online"

kamailio.cfg
if(redis_cmd("srvN", "HGET usuario:2001 status", "res")) {
    xlog("L_INFO","array size: $redis(res=>size) - type: $redis(res=>type) - value: $redis(res=>value)\n");    
}
output /var/log/syslog

if you can share your code, it would be great :)

Thanks !

Hi,
I dont have my config at cell will share mine later. Meanwhile can you try HGET only to pull that 1 value plus use
$redis(res=>value) with that.

Hello Community,

I'm trying to read data (hash) stored in redis database, from kamailio script.

I read the module documentation ndb_redis: 
But I'but I don't understand what I'm doing wrong :/

With someone has had experience this?

My platform:

My script:

modparam("ndb_redis", "server", "name=srvN;addr=127.0.0.1;port=6379;db=1")
modparam("ndb_redis", "init_without_redis", 1)

if(redis_cmd("srvN", "HMGET usuario:2002 status", "res")) {
xlog("L_INFO","array size: $redis(res=>size) - type: $redis(res=>type) - value: $redis(res=>value[0]) $redis(res=>value[1]) \n");    
}

The output of syslog (I don't see errors):

It can be seen that $redis(res=>size) & $redis(res=>type) return values, not so with $redis(res=>value[0]).

By last, I share de output of redis CLI:

127.0.0.1:6379> hget usuario:2002 status 
"Online"

Cheers,
