Wasm-based Telemetry (Experimental)

By default, telemetry generation is enabled as compiled-in Istio proxy filters. The same filters are also compiled to WebAssembly (Wasm) modules and shipped with Istio proxy. To enable telemetry generation with the Wasm runtime, install Istio with the preview profile:

$ istioctl manifest apply --set profile=preview

Alternatively, set the following two values to enable Wasm-based Telemetry with the default profile:

$ istioctl manifest apply --set values.telemetry.v2.metadataExchange.wasmEnabled=true --set values.telemetry.v2.prometheus.wasmEnabled=true

Was this information useful?

Do you have any suggestions for improvement?

Thanks for your feedback!
