我有一个Mongo部署，带有一个指标导出器侧柜。现在，当我在Grafana中加载相关 Jmeter 板时，指标没有显示-似乎导出器没有丢弃所有指标：

什么在起作用

只有Mongo UP指标起作用，即mongodb_up{env=~""}和 * 部分 * 服务器指标

什么不起作用

Jmeter 板中的以下所有度量均未显示任何数据：操作计数器、复制集度量、游标度量
我的配置：部署.yaml（使用***Percona MongoDB导出程序***）

我所尝试的

1.我已经尝试使用***Bitnami MongoDB Exporter***版本的边车。它产生了完全相同的结果：

- name: metrics
      image: docker.io/bitnami/mongodb-exporter:0.32.0-debian-11-r5
      imagePullPolicy: "IfNotPresent"
      securityContext:
        runAsNonRoot: true
        runAsUser: 1001
      command:
        - /bin/bash
        - -ec
      args:
        - |
          /bin/mongodb_exporter --web.listen-address ":9216" --mongodb.uri "mongodb://$MONGODB_ROOT_USER:$(echo $MONGODB_ROOT_PASSWORD | sed -r "s/@/%40/g;s/:/%3A/g")@localhost:27017/admin?" 
      env:
        - name: MONGODB_ROOT_USER
          value: "root"
        - name: MONGODB_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: mongodb-prom
              key: mongodb-root-password
      ports:
        - name: metrics
          containerPort: 9216
      livenessProbe:
        failureThreshold: 3
        initialDelaySeconds: 15
        periodSeconds: 5
        successThreshold: 1
        timeoutSeconds: 5
        httpGet:
          path: /
          port: metrics
      readinessProbe:
        failureThreshold: 3
        initialDelaySeconds: 5
        periodSeconds: 5
        successThreshold: 1
        timeoutSeconds: 1
        httpGet:
          path: /
          port: metrics
      resources:
        limits: {}
        requests: {}
        ```

1.我将遵循给定here的参考实现，并将clusterMonitor角色添加到db用户，如下所示：
将角色授予用户（“root”，[{角色：“群集监视器”，数据库：“管理员”}，{角色：“读取”，数据库：“本地”}]）
当我执行db.getUsers();的时候

[
        {
                "_id" : "admin.root",
                "userId" : UUID("d8e181fc-6429-447e-bbcb-cec252f0792f"),
                "user" : "root",
                "db" : "admin",
                "roles" : [
                        {
                                "role" : "clusterMonitor",
                                "db" : "admin"
                        },
                        {
                                "role" : "root",
                                "db" : "admin"
                        },
                        {
                                "role" : "read",
                                "db" : "local"
                        }
                ],
                "mechanisms" : [
                        "SCRAM-SHA-1",
                        "SCRAM-SHA-256"
                ]
        }
]

即使在授予这些角色后， Jmeter 板仍无法加载缺少的指标。
1.我已经更新了 Jmeter 板JSON * 中的Prometheus和Grafana版本，以匹配我安装的版本 *（这会有什么影响吗？）
我使用的默认 Jmeter 板是here。
我错过了什么？
