I am using SignalFX to create an alert via metrics from a Google Cloud GKE cluster. I want to be able to trigger an alert when number-of-nodes-in-node-pool == node-pool-max-size. I am not using GCP autoscaling under the k8s cluster as the cluster is managing the node pool itself. I can use metric "instance_group/size" to get the current number of nodes in the node group but cannot find a metric to get node-pool-max-size (I cannot use an autoscaler metric as autoscaler is not being used). Can anyone point me to a metric or combination of metrics that can be used here?

As per the documentation currently there is no metric to monitor the node pool maximum size. The metric you are using Instance_group/size is the only metric to monitor the current number of nodes and maximum size of node pool.
