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?

对于任何在这方面有困难的人,我必须为容器添加--collect-all和--compatibility-mode标志,以提取指标,如下面的配置所示:
