如何编写一个查询,在过去24小时内输出实例的平均内存使用量？以下查询显示当前的内存使用情况

100 * (1 - ((node_memory_MemFree + node_memory_Cached + node_memory_Buffers) / node_memory_MemTotal))

对于CPU,我能够使用愤怒

100 * (1 - avg(irate(node_cpu[24h])) BY (instance))

如何使用irate和avg作为内存？

我有一个具有许多值的映射变量(NACL规则).我正在尝试相应地添加规则

variable "rules" {
  default = {
    a = "200,false,tcp,allow,0.0.0.0/0,23,23"
    b = "100,true,tcp,allow,0.0.0.0/0,1024,65535"
  }
}


resource "aws_network_acl_rule" "bar" {
  network_acl_id = "<id>"
  rule_number    = "${split(",",element(values(var.rules),count.index))[0]}"
  egress         = "${split(",",element(values(var.rules),count.index))[1]}"
  protocol       = "${split(",",element(values(var.rules),count.index))[2]}"
  rule_action    = "${split(",",element(values(var.rules),count.index))[3]}"
  cidr_block     = "${split(",",element(values(var.rules),count.index))[4]}"
  from_port      = "${split(",",element(values(var.rules),count.index))[5]}"
  to_port        = "${split(",",element(values(var.rules),count.index))[6]}"
  count          = "${length(values(var.rules))}"
}

错误: expected "}" but found "["

由于不支持带有列表作为值的映射,因此我尝试拆分值并进行迭代
