几个工具收集(glances,jq)

glances工具:性能监控,类似top命令,监控cpu,内存,硬盘等性能参数等等

yum -y install epel-release

yum -y install glances

直接执行glances

jq   格式化工具,变成json格式

#########变成json格式

[root@host101 ~]# echo '{"name":"阿良","sex":"男","city":"北京"}' |jq
{
  "name": "阿良",
  "sex": "男",
  "city": "北京"
}
[root@host101 ~]#
[root@host101 ~]#
[root@host101 ~]#
[root@host101 ~]#
########通过jq获取字段值
[root@host101 ~]# echo '{"name":"阿良","sex":"男","city":"北京"}' |jq ".name"
"阿良"
[root@host101 ~]# echo '{"name":"阿良","sex":"男","city":"北京"}' |jq ".city"
