My architecture consists of Kafka logstash elasticsearch, i wrote a ruby code to calculate a KPI in logstash, everything was working fine but some days pass by and that KPI i made has been reset to 0 and only that KPI, i've also created some scripted fields in kibana i somehow messed them up and immediately got data loss when i was observing my saved search not everything but some of them, so i deleted those scripted fields and created proper ones that they where successful but after some time the same issue got back

this is my ruby code at the logstash level

> ```
> mutate { add_field => { "[@metadata][task]" => "constant" } }
> aggregate {
> task_id => "%{[@metadata][task]}"
> code => '
> map["total"] ||=0
> t = event.get("[payload][type]")
> s = event.get("[payload][status]")
> if t == "topup" && s == "success"
> map["total"] += event.get("[payload][amount]")
> elsif t == "cashout" && s == "success"
> map["total"] -= event.get("[payload][amount]")
> end
> event.set("total", map["total"])
> '
> }
> 
> ```

and the scripted fields where normal doc["fieldname"] i've just used it to rename some fields

What problem are you having with that aggregate filter?

@Badger I still don't know yet but after a while the total field gets reset to 0 i have to delete the index and index back again to have the correct value  
ps: i'm using --pipeline.workers 1

I would only expect that to happen when logstash restarts.

@Badger I never restarted the server, i have a ec2 instance do you think when amazon automaticly backups the server it get restarted ? that is a slight chance because if it has been restarted all the other services will go down and will not automatically restart, and what about the data loss i'm facing ? is there something i can do so you can incarnate my problem ?

Is there a other way i can calculate that KPI probably in Elasticsearch ?
