prometheus - 在普罗米修斯中划分两个指标

Question

我有两个指标，来自电报。

第一个指标

vsphere_host_mem_active_average{esxhostname=~"esx1"}

给出一个值

vsphere_host_mem_active_average{clustername="BCH1",collector="telegraf",dcname="DC",esxhostname="esx1",host="vm01",hostname="hostname1",instance="localhost:9273",job="vSphere",moid="host-78563",source="esx1",type="vmware",vcenter="vmc"}    17763152

第二个

vsphere_vm_mem_granted_average{esxhostname=~"esx1"})

给出几个不同的标签

1.

vsphere_vm_mem_granted_average{clustername="BCH1",dcname="DC",esxhostname="esx1",guest="debian9_64",host="vm01",moid="vm-79139",source="vm01",uuid="42244f7b-abeb-92be-3e67-af19a9d8dfbd",vcenter="vmc",vmname="vm01"} 4.19418e+06

2.

vsphere_vm_mem_granted_average{clustername="BCH1",dcname="DC",esxhostname="esx1",guest="debian9_64",host="vm01",moid="vm-79146",source="vm01",uuid="4224ed0c-f306-202c-fc99-35e48fe52370",vcenter="vmc",vmname="vm02"} 8.377904e+06

是否有可能获得每个标签集的第一个值除以第二个值的结果？

标签： prometheus

Answer 1

也许我没有完全正确地解释这个问题，但是如果您想将 2 个指标分开，您只需在 PromQL 中使用“/”运算符，此处记录：https ://prometheus.io/docs/prometheus/latest/querying /运营商/

作为使用上述值的示例，您将使用的查询类似于：

(vsphere_host_mem_active_average{clustername="BCH1",collector="telegraf",dcname="DC",esxhostname="esx1",host="vm01",hostname="hostname1",instance="localhost:9273",job="vSphere",moid="host-78563",source="esx1",type="vmware",vcenter="vmc"}/vsphere_vm_mem_granted_average{clustername="BCH1",dcname="DC",esxhostname="esx1",guest="debian9_64",host="vm01",moid="vm-79139",source="vm01",uuid="42244f7b-abeb-92be-3e67-af19a9d8dfbd",vcenter="vmc",vmname="vm01"})
