skywalking--Prometheus Fetcher使用

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 application.yml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:""}

 

3.开启Prometheus Fetcher

修改application.yml：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}

 

4.重启skywalking，发现多了1234端口，并测试验证

采集规则配置：/config/fetcher-prom-rules/self.yaml
