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
}
};
[embedmd]:# (../examples/eks-cni-example.jsonnet)
```jsonnet
local kp = (import 'kube-prometheus/kube-prometheus-eks.libsonnet') + {
local service = kp.core.v1.service,
local servicePort = kp.core.v1.service.mixin.spec.portsType,
_config+:: {
namespace: 'monitoring',
},
prometheus+: {
AwsEksCniMetricService:
service.new('aws-node', { 'k8s-app' : 'aws-node' } , servicePort.newNamed('cni-metrics-port', 61678, 61678)) +
service.mixin.metadata.withNamespace('kube-system') +
service.mixin.metadata.withLabels({ 'k8s-app': 'aws-node' }) +
service.mixin.spec.withClusterIp('None'),
