table表中的设置：
instant:表示只显示当前值

cpu使用率
sum(netdata_system_cpu_percentage_average{dimension!="idle", group="$group", env="$env"}) by (instance)
要点解释：
dimension:维度
idle:闲置的

内存使用率
sum(netdata_system_ram_MiB_average{dimension="used", group="$group", env="$env"}) by (instance) / sum(netdata_system_ram_MiB_average{group="$group", env="$env"}) by (instance) * 100

磁盘总使用率
sum(netdata_disk_space_GiB_average{dimension="used",group="$group",env="$env"}) by (instance) / sum(netdata_disk_space_GiB_average{group="$group", env="$env"}) by (instance) * 100


/分区使用率
sum(netdata_disk_space_GiB_average{dimension="used",family="/", group="$group",env="$env"}) by (instance) / sum(netdata_disk_space_GiB_average{group="$group", family="/", env="$env"}) by (instance) * 100


/data分区使用率
sum(netdata_disk_space_GiB_average{dimension="used",family="/data", group="$group",env="$env"}) by (instance) / sum(netdata_disk_space_GiB_average{group="$group", family="/data", env="$env"}) by (instance) * 100
