monitoring CPU/mem usage on gke

I recently launched with gke and kubernetes in production. I have regular outages with no obvious reasons. No event shows anything, pods are not restarting and seems stable. I have a similar qa env that has no issue at all whereas it's way smaller.

Where can I find potential infos on the outage reason?

Stack driver makes you pay and configure it... kubernetes comes with a tool for it... just use this:

kubectl top nodes

al@host:~/$ kubectl top nodes
NAME                             CPU(cores)   CPU%      MEMORY(bytes)   MEMORY%
gke-learn-pool-1-10f60e0a-s44c   104m         11%       1008Mi          86%

You can also go under clusters -> Cluster -> nodes -> Node

Update: Stack Driver deprecated all load monitoring plugins. It's K8s or the highway now.

You can see monitoring data for your cluster using Stackdriver. There's a brief walkthrough of how to use it for GKE in this blog post. You may also want to check out the general Kubernetes application troubleshooting guide.

What are the symptoms of the outage?
