Hello everyone,

I am wondering if it is possible to do **advanced mathematical operations with ELK**. Here is an example of what I would like to do:

I have logs from my radio network and for each device i have a frame counter in every packet received. What I want to do is to compute the percentage of packets lost in my network by checking the mathematical difference between frame counters for every device. Currently, i can't do it by aggregration through Kibana.

In the elastic website, I saw that there is the alternative of java native script that can allow me to manipulate my fields and data. However, I have some worries about it. First, I haven't seen if I could display the results in kibana. Secondly, I would like to compute my percentages in function of time and i don't know if it is possible with that way.

Furthermore, if you have another alternative it is fine with me.

Thanks in advance.

Sen
