3.2. 在 Red Hat OpenShift Container Platform 中创建 ServiceTelemetry 对象

流程

1. 要创建可生成使用默认值的 STF 部署的 ServiceTelemetry 对象，请创建一个带有空 spec 参数的 ServiceTelemetry 对象：

   $ oc apply -f - <<EOF
   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   metadata:
     name: default
     namespace: service-telemetry
   spec: {}
   EOF

   要覆盖默认值，请定义您要覆盖的参数。在本例中，通过将 enabled 设置为 true 来启用 ElasticSearch：

   $ oc apply -f - <<EOF
   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   metadata:
     name: default
     namespace: service-telemetry
   spec:
     backends:
       events:
         elasticsearch:
           enabled: true
   EOF

   使用空 spec 参数创建 ServiceTelemetry 对象会导致带有以下默认设置的 STF 部署：

   apiVersion: infra.watch/v1beta1
   kind: ServiceTelemetry
   metadata:
     name: default
   spec:
     alerting:
       alertmanager:
         storage:
           persistent:
             pvcStorageRequest: 20G
             storageSelector: {}
           receivers:
             snmpTraps:
               enabled: false
               target: 192.168.24.254
           strategy: persistent
       enabled: true
     backends:
       events:
         elasticsearch:
           enabled: false
           storage:
             persistent:
               pvcStorageRequest: 20Gi
               storageSelector: {}
             strategy: persistent
       metrics:
         prometheus:
           enabled: true
           scrapeInterval: 10s
           storage:
             persistent:
               pvcStorageRequest: 20G
               storageSelector: {}
             retention: 24h
             strategy: persistent
     graphing:
       enabled: false
       grafana:
         adminPassword: secret
         adminUser: root
         disableSignoutMenu: false
         ingressEnabled: false
         baseImage: docker.io/grafana/grafana:8.1.2
     highAvailability:
       enabled: false
     transports:
       qdr:
         enabled: true
         web:
           enabled: false
     clouds:
       - name: cloud1
         metrics:
           collectors:
             - collectorType: collectd
               subscriptionAddress: collectd/telemetry
               debugEnabled: false
             - collectorType: ceilometer
               subscriptionAddress: anycast/ceilometer/metering.sample
               debugEnabled: false
             - collectorType: sensubility
               subscriptionAddress: sensubility/telemetry
               debugEnabled: false
         events:
           collectors:
             - collectorType: collectd
               subscriptionAddress: collectd/notify
               debugEnabled: false
             - collectorType: ceilometer
               subscriptionAddress: anycast/ceilometer/event.sample
               debugEnabled: false

   要覆盖这些默认值，请将配置添加到 spec 参数。

2. 在 Service Telemetry Operator 中查看 STF 部署日志：

   $ oc logs --selector name=service-telemetry-operator
