Arithmetical operations on fields?

Hi,

I currently using metricbeat-5.4.
I monitor some metrics and I add some fields on documents but can I make some arithmetical operations on fields ?

Thanks

You can do it on the Kibana side using the new Time Series Visual Builder.

OK but can I add modified fields on my documents ?

We use these data in Grafana Dashboards so I want to make operations on some fields in order to use them in Grafana

In the elastic stack we prefer to do calculations on the querying side, but if you really need to compute new fields at the ingestion time, I'd recommend checking out the Ingest Node functionality of Elasticsearch, especially the Script processor.
