Hello everyone, I have an interesting question regarding labels. So I am
trying to pull values with metrics specifically PVC data and pretty much
would like to produce a label with the yielded results.
For instance, here is my simple query argument for the PVCs within one of
my environments looking for statefulsets that have PVCs with storage
utilization that is 40% or higher. Specifically, is there a way to create a
label for the value output? This is so when our alerts fire, we could
declare a variable which produces accurate info in the alert message
itself. Does anyone have any good ideas on this?
Specifically I am trying to produce a {{ $labels.storage }} label, based on
the value produced by the expression below:
```kubelet_volume_stats_available_bytes/kubelet_volume_stats_capacity_bytes
< .60
Element:
{endpoint="http-metrics",instance="10.xxx.58.210:10255",job="kubelet",metrics_path="/metrics",namespace="{infra}",node="gke-xxx-xxx-xxx-001-stateful-394fxxxx-xxxx",persistentvolumeclaim="prometheus-prometheus-operator-prometheus-db-prometheus-prometheus-operator-prometheus-0",service="prometheus-operator-kubelet"}
Value:
0.505853632940522```
We are also utilizing good ole' Alertmanager:
