Hello...
I am trying to extract a forex rate from an array based on the year and month fields. I have a array which is like this:
// forexRate =>
// 2017;7;0.0001105093, 2017;8;0.0001116904, 2017;9;0.0001114438, 2017;10;0.0001118130, 2017;11;0.0001110309, 2017;12;0.0001111167, 2018;1;0.0001111290, 2018;2;0.0001113834, 2018;3;0.0001113524;
I have already fields of integer for year and month which are:
// year => 2017
// month => 9
I want to user the year and month to pick the third value
// grok {
// match => [ "forexRate" , "%[year];%[month];%{NUMBER:rate}" ]
// add_field => [ "reportRate" , "%{rate}" ]
// }
Then use the rate to calculate a newCurrency
// ruby {
code => 'event.set("newCurrency", event.get("numberCount").to_i * 1 * [rate])
}
How can I use the fields year and month to pick the third value in the array??
