Best way to expose application logs on istio standard tool?


I’m using Istio with sidecar injection and with standard tools: Prometheus, Grafana, Jaeger and Kiali.

I would like to export some logs of my application, for example an exception handled by the code (so the application continues to work).

If I understand Istio correctly, the proxy (Envoy) is already connected to the logging tool (Jaeger), so how to send a custom log from my node.js application?

Thanks for your help,
