+# CNI monitoring special configuration updates for EKS
+
+AWS EKS uses [CNI](https://github.com/aws/amazon-vpc-cni-k8s) networking plugin for pod networking in Kubernetes using Elastic Network Interfaces on AWS
+
+One fatal issue that can occur is that you run out of IP addresses in your eks cluster. (Generally happens due to error configs where pods keep scheduling).
+
+You can monitor the `awscni` using kube-promethus with :
+```
+local kp = (import 'kube-prometheus/kube-prometheus.libsonnet') +
+ (import 'kube-prometheus/kube-prometheus-aws-eks-cni.libsonnet') +
+ {
+ _config+:: {
+ # ... config here
+ }
+ };
+```
+
+After you have the required yaml file please run
+
+```
+kubectl apply -f manifests/prometheus-serviceMonitorAwsEksCNI.yaml
+```
