zabbix监控redis

1）agent端配置

• 安装redis

  yum install epel-release -y 
  yum install redis -y 

• 配置认证密码

  #vim /etc/redis.conf
  requirepass redhat 
  #systemctl restart redis

• 获取redis的item值shell脚本

  #vim /etc/zabbix/zabbix_agentd.d/redis_status.sh
  #/bin/bash 
  R_COMMAND="$1"
  R_PORT="6379"
  R_SERVER="127.0.0.1"
  PASSWD="redhat"
  redis_status(){
     (echo -en "AUTH $PASSWD\r\nINFO\r\n";sleep 1;) | /usr/bin/nc "$R_SERVER" "$R_PORT" > /tmp/redis_"$R_PORT".tmp
    REDIS_STAT_VALUE=$(grep "$R_COMMAND:" /tmp/redis_"$R_PORT".tmp | cut -d ':' -f2)
     echo "$REDIS_STAT_VALUE"
  }
  case $R_COMMAND in
  used_cpu_user_children)
  redis_status "$R_PORT" "$R_COMMAND"

  esac

• 授权

  chmod +x /etc/zabbix/zabbix_agentd.d/redis_status.sh

• 修改agent配置文件

  #vim /etc/zabbix/zabbix_agentd.d/userparameter_redis.conf
  UserParameter=redis.status[*],/etc/zabbix/zabbix_agentd.d/redis_status.sh $1

• 重启agent服务

  systemctl restart zabbix-agent

  2）server端配置

• server端获取key值

  # zabbix_get -s 192.168.1.33 -k redis.status
  USAGE:/etc/zabbix/zabbix_agentd.d/redis_status.sh {used_cpu_user_children|used_cpu_sys|total_commands_processed|role|lru_clock|latest_fork_usec|keyspace_misses|keyspace_hits|keys|expires|expired_keys|connected_clients|changes_since_last_save|blocked_clients|bgrewriteaof_in_progress|used_memory_peak|used_memory|used_cpu_user|used_cpu_sys_children|total_connections_received}
  # zabbix_get -s 192.168.1.33 -k redis.status[used_cpu_sys]
  0.11

• 键值

  redis.status[used_cpu_user_children]
  redis.status[used_cpu_sys]
  redis.status[total_commands_processed]
  redis.status[role]
  redis.status[lru_clock]
  redis.status[latest_fork_usec]
  redis.status[keyspace_misses]
  redis.status[keyspace_hits]
  redis.status[keys]
  redis.status[expires]
  redis.status[expired_keys]
  redis.status[connected_clients]
  redis.status[changes_since_last_save]
  redis.status[blocked_clients]
  redis.status[bgrewriteaof_in_progress]
  redis.status[used_memory_peak]
  redis.status[used_memory]
  redis.status[used_cpu_user]
  redis.status[used_cpu_sys_children]
  redis.status[total_connections_received]

• 创建模板
  
• 创建监控项
  

• 其它省略，验证图形
