Hi, I was trying to convert the value of one field with another, for example:
I currently have a field called "priority" and the value of that field is = 1, priority=1. What I want to do is change that value 1 to critical, that is, priority=critical.
I made a conditional but it doesn't work, am I doing something wrong?
if [priority] == "1" {
mutate {
replace =\> ["priority", "critical"]
}
Greetings

Depend on data type:
"1" - string
1 - integer
I assume it's number, so:
```auto
if [priority] == 1 {
mutate { convert => { "priority" => "string" } }
mutate { replace => ["priority", "critical"] }
}
```
If you have issues, add ruby debug in output.
```auto
output {
stdout { codec => rubydebug{} }
...
}
```
