Welcome to our community! :smiley:

That's a massively bad idea and I'm sorry to say that there's no one here that should be helping you do this.

Why do you think you need to do this?

What is the output of:

GET /
GET /_cat/nodes?v
GET /_cat/health?v
GET /_cat/indices?v

If some outputs are too big, please share them on gist.github.com and link them here.
