OpenSIPS3.4 load balancer fetch_freeswitch_stats 测试

最近查了下，感觉是这样的：

REGISTER 请求 dispatcher 到 FreeSWITCH

INVITE 请求 load_balancer 到 FreeSWITCH

我不太熟悉 OpenSIPS，可能我讲的不对

此外，留意到手册

https://www.opensips.org/Documentation/Install-DBSchema-3-4#GEN-DB-LOAD-BALANCER

Probing mode (0-none, 1-if disabled, 2-all the time)

讲的很清楚

手册也讲了，channels=fs://:ClueCon@127.0.0.1:8021

到底如何，回头测试下

试了下，貌似不难

#### FREESWITCH module
loadmodule "freeswitch.so"
modparam("freeswitch", "event_heartbeat_interval", 20)

#### LOAD BALANCER module
loadmodule "load_balancer.so"
# modparam("load_balancer", "db_url",    "mysql://opensips:opensipsrw@127.0.0.1/opensips") # CUSTOMIZE ME
modparam("load_balancer", "probing_method", "OPTIONS")
modparam("load_balancer", "probing_interval", 30)

modparam("load_balancer", "fetch_freeswitch_stats", 1)

数据库可以这样：

insert into load_balancer (group_id, dst_uri, resources, probe_mode) values (1, 'sip:172.16.99.205:5080', 'channels=fs://:ClueCon@172.16.99.205:8021', 2);

还有个 freeswitch_scripting 模块，以后有机会测试一把
