Hello,
We added a new feature to the ndb_redis module, similar to how the rtpengine_disable_tout
parameter of the rtpengine module works.
If a number of consecutive commands to a redis server fail, that server is temporarily
disabled. This is configurable by parameters: "allowed_timeouts" and
"disable_time".
Disabling a server means that for "disable_time" seconds any command to that
sever will not send the command to the server, but an error is returned instead.
For example if allowed_timeouts is configured to 0 and disable_time to 30, the first time
redis_cmd or redis_execute functions fail the server will be disabled for 30 seconds.
The server information is retained by each Kamailio process individually, so this means
that disabling a server is done by that process only and not globally.
