其使用ASCII码（如连字符、问号、冒号、逗号等）构造数据块（标量值或哈希码），赋予执行权限 将check_redis.php和check_redis.pl复制到/usr/lib/nagios/plugins/目录。

在redis服务瓶颈或者异常时候即使报警通知，定义redis监控服务选项 [root@wgq objects]# vim /usr/local/nagios/etc/objects/services_redis.cfg # Redis Master 监控选项 define service { host_name cache-1 servicegroups Redisservices service_description Redis Master Clients check_command check_redis!6379!connected_clients，~!600， wont make Running Build test Make had some problems，~，~ max_check_attempts 5 normal_check_interval 3 retry_check_interval 2 check_period 24x7 notification_interval 10 notification_period 24x7 notification_options w。
