I would think that sorting the keys is just a waste of time. The json format output is currently performance limited to around 15,000 events per second on the latest generation of CPU.
I would be in favor of doing ANYTHING that could speed that up. Perhaps the ability to sort, and the ascending/descending order should be options to the json output template.

<div>Hi,<br>
<br>
</div>
I've encountered a case where format-json orders keys not alphabetically, but rather in the other direction. Can you remember any reason for that?<br>
<br>
</div>
This is the only patch needed to fix the order, but I've figured there may have been some reason behind the ordering.<br>

{<br>
- return strcmp(s2, s1);<br>
+ return strcmp(s1, s2);<br>
}<br>

<div>Thanks in advance, <br>
