The value is sample-based and only a rough estimate. That's why only a percentage is shown. The purpose is to find the worst offenders. Thread allocation is more precise as it looks at a byte value stored in the thread.</div>

(I might come off as negative to your suggestions, but when I implemented 'jfr view' I tried many different views and layouts, only the best made it. The main reason I created the query language was so I could quickly try things out.)</div>

<div>hi all</div>
<div><br>
</div>
<div><b>jfr view</b> has three predefined views regarding allocation: <b>allocation-by-thread</b>,
<b>allocation-by-class</b>,<b> allocation-by-site</b>.</div>
<div>Currently, these three views only show percentages. </div>
<div>Usually, we will first look at the absolute value of memory application (total number of allocated bytes). </div>
<div>When the absolute value is larger enough, the items with larger proportions are more meaningful.</div>
<div>I don’t know if I can add <b>Allocated</b> column to these three views, similar to the
<b>thread-allocation</b> view.</div>
<div><br>
</div>
<div> Allocation by Class</div>
<div>Object Type Allocated Allocation Pressure</div>
