istio如何采集method、url指标

创建一个Telemetry资源

providers固定为prometheus

path的值可以是request.url_path或request.path

其中request.url_path不包含路径后的参数，request.path包含路径后的参数

可通过selector设置选择的pod，若不设置，则选择命名空间下所有pod

apiVersion: telemetry.istio.io/v1alpha1
kind: Telemetry
metadata:name: add-method-urlnamespace: your-namespace
spec:selector:matchLabels:app: my-appmetrics:- providers:- name: prometheusoverrides:- match:metric: REQUEST_COUNTtagOverrides:method:value: request.methodpath:value: request.url_path
