（十二）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=""
R_SERVER="127.0.0.1"
PASSWD="redhat"
redis_status(){
   (echo -en "AUTH $PASSWD\r\nINFO\r\n";sleep ;) | /usr/bin/nc "$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" "$R_COMMAND"
    ;;
    used_cpu_sys)
    redis_status "$R_PORT" "$R_COMMAND"

    echo $"USAGE:$0 {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}"
    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 $

• 重启agent服务

  systemctl restart zabbix-agent

sys

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
