Hello @migueleliasweb,the CNI metrics helper plugin https://github.com/aws/amazon-vpc-cni-k8s/tree/master/charts/cni-metrics-helper provides all these details. Have you tried installing this plugin and setting this up?
Hi @orsenthil , I wasn't aware of this helper. I'll definitely be trying to deploy it and report back with some findings. Thank you heaps!
What would you like to be added:
Metrics to the amount of allocated IPs/ENIs/Networks per CNI container. This is critical for users to foresee upcoming IP exhaustion issues on their VPCs and Subnets.
Why is this needed:
Currently, the AWS provides the amount of
Available IPv4 addresses
in their subnet page but the count is not a live number and only updates at a certain frequency. Sometimes, users with bigger clusters, might think they have loads of IPs available but under the hood the VPC CNI is throwing errors due to IP allocations on certain subnets.
