1.准备：
实验版本：skywalking 9.1.0
官网：https://skywalking.apache.org/docs/main/v9.1.0/en/setup/backend/prometheus-metrics/
2.开启prometheus遥测数据 修改skywalking配置，修改${SW_TELEMETRY:prometheus}telemetry:
selector: ${SW_TELEMETRY:prometheus}
none:
prometheus:
host: ${SW_TELEMETRY_PROMETHEUS_HOST:0.0.0.0}
port: ${SW_TELEMETRY_PROMETHEUS_PORT:1234}
sslEnabled: ${SW_TELEMETRY_PROMETHEUS_SSL_ENABLED:false}
sslKeyPath: ${SW_TELEMETRY_PROMETHEUS_SSL_KEY_PATH:""}
sslCertChainPath: ${SW_TELEMETRY_PROMETHEUS_SSL_CERT_CHAIN_PATH:""}
2.开启Prometheus Fetcher
修改：selector: ${SW_PROMETHEUS_FETCHER:default}
prometheus-fetcher:
selector: ${SW_PROMETHEUS_FETCHER:default}
default:
enabledRules: ${SW_PROMETHEUS_FETCHER_ENABLED_RULES:"self"}
maxConvertWorker: ${SW_PROMETHEUS_FETCHER_NUM_CONVERT_WORKER:-1}
重启skywalking，发现多了1234端口，并测试验证
