If this is indeed true (" # stdio is a debug adapter in istio-telemetry, it is not recommended for production use."), it feels like something that needs to be called out as a caution in the documentation:
I only ask because I am literally two days from promoting into production a telemetry logging setup that uses stdio with a fluentd container log scraper to gather Istio mesh logs into the logging system.
Thanks! I was able to connect on the Istio Slack with some of the developers and they did indeed caution that stdio is not optimized in ways you’d probably want in a production environment.
I am going to move to delivering metrics to fluentd through the native fluentd adapter instead.
