Wasm-based Telemetry
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 install --set profile=preview
Alternatively, set the following two values to enable Wasm-based Telemetry with the default
profile:
$ istioctl install --set values.telemetry.v2.metadataExchange.wasmEnabled=true --set values.telemetry.v2.prometheus.wasmEnabled=true
