Hello,

I have trouble finding documentation for paintless script. [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-painless.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-painless.html)  
I don't know java nor groovy. I just wanted to do a max of 3 values in a gauge.  
So I will display 99% red color if one one of CPU, SWAP, DISK goes to 99%.

Anyone can help me find examples?

I think this should work for you:

```auto
Math.max(params.swap, Math.max(params.cpu, params.disk))

```

Painless is a pass-through for a lot of basic java functions (like `Math.max()`), hence the syntax in this case 🙂
