Hello,
I'm watching in the Elastic Support Matrix that AIX is not supported by any beat or logstash version. I want to know if you have plans to have this function or if there are other ways to install beats in this S.O.
Thanks.
Welcome to our community! 
There's no upcoming support that I am aware of, you can see previous threads on this topic with more detail. The TLDR is that golang support is difficult.
