<p>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.</p>

<p>Where can I find potential infos on the outage reason?</p>

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

<p><code>kubectl top nodes</code></p>

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

<p>You can also go under clusters -> Cluster -> nodes -> Node </p>

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