Telemetry V2 with Wasm runtime (Experimental)
Since Istio 1.5, by default Telemetry V2 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 V2 with 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 v2 with the default
profile:
$ istioctl manifest apply --set values.telemetry.v2.metadataExchange.wasmEnabled=true --set values.telemetry.v2.prometheus.wasmEnabled=true
