我之前使用elk+redis+filebeat搭建了日志平台，现在将redis替换成codis之后，logstash报错：

# [2020-06-18T11:20:54,146][WARN ][logstash.inputs.redis] Redis connection problem {:exception=>#<Redis::CommandError: ERR handle request, command'BLPOP' is not allowed>} 


# [2020-06-18T11:19:12,920][WARN ][logstash.inputs.redis] Redis connection problem {:exception=>#<Redis::CommandError: ERR max number of clients reached>}strong text

这是我的 logstash 配置：

/usr/local/elk/logstash/config/logstash_es.conf

input {
  redis {
     data_type => "list"
     key => "elk"
     host => "192.168.124.224"
     port => "19000"
     batch_count => "1"
     threads => 5
     codec => "json"
     }
}

output {
    if [fields][log_type] == "php" {
          elasticsearch {
                hosts => ["192.168.124.225:9200"]
                index => "php-%{+YYYY.MM.dd}"
                action =>  "index"
                }
               }
}

Codis 提到它们与 twemproxy 100% 兼容。根据 twemproxy 文档该BLPOP命令不受支持。因为logstash Redis 输入插件描述BLPOP为必需功能，这告诉我 Codis 根本不能与 Logstash 一起使用。
