Hello, the item "Logstash duration per event"
with this formula "last("logstash.events.duration_in_millis") / last("logstash.events.out")"

Give me this error "Cannot evaluate function "last()": item "Template App Logstash Full:logstash.events.duration_in_millis" does not exist."

But when I test the item key "logstash.stats.events" from "Logstash stats events raw: Logstash events duration
logstash.events.duration_in_millis" work OK.

How could I fix it ?
Is the main important item to debug performance in main and many pipelines.

Thanks
Diego

HTTP Item discovery.

JSONpath functionality is limited in zabbix, therefore we cannot simply filter out just pipeline names and make discovery list. But it is possible to do Javascript preprocessing . With this maybe agent discovery is not needed ?

Pipeline discovery example.

URI = _node/pipelines?pretty

zabbix discovery rule / Preprocessing Steps / JavaScript

parameters:

const obj = JSON.parse(value);
const pipelines = Object.keys(obj.pipelines);
var djson = [];
pipelines.forEach(function(name) {djson.push({"pipeline":name})}); 
djson = JSON.stringify({"data": djson});
djson = JSON.parse(djson.replace(/"/g,'""'));
djson = JSON.stringify(djson);
return djson;

LLD macros:

LLD macro = {#PIPELINE}
JSON Path = $..pipeline.first()

Would you be able to add a metric for lag between input and output?

I have checked all logstash versions and this key does not exist in any API. what is the exact logstash version you are using?
