<p>I have setup a cron job on GCP Kubernetes. It runs once per day at 10:00am.
The job runs as expected however, I don't really understand what the charts say on the GCP K8S console.</p>

<p><a href="https://i.stack.imgur.com/cwXb4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cwXb4.png" alt="enter image description here"></a></p>

<p>As shown in the charts, there are around 1.5 CPU and 8G RAM at this point, when the cron job is not running. I expect the current usage should be zero as it is <strong>not</strong> running. </p>

<p>Could anyone see what is wrong? or I read the charts wrong?</p>

<p>Note I do retain 7 jobs in the history. Each job ran about 15sec and completed successfully.</p>

<pre><code>State:          Terminated

I found all graphs from other cron jobs all look the same. Is it something I setup wrong?</p>

<p>I reproduced your situation by that way:</p>

<ol>
<li>Created CronJob with a name "Application"</li>
<li>Added an application using Deployment with a name "Application"</li>
</ol>

<p>And now, I see on graphics of Cron Job details information not only about a cronjob itself, but also about an application.</p>

<p>So, I think, dashboard using <strong>name of object</strong> for getting a data.</p>

<p>Looks like you have any other deployment, replicaset etc. which always running and has a same name as your cronjob and on graphics you see the mix of data from it and from your cronjob.</p>
