docker-compose部署kafka-exporter采集kafka指标，报错 was collected before with the same name and label values

1. 运行环境#

linux amdx86_64 基础环境
docker-compose 版本：
./docker-compose –version
docker-compose version: 1.3.1
CPython version: 2.7.9
OpenSSL version: OpenSSL 1.0.1e 11 Feb 2013

docker 版本：
docker –version
Docker version 20.10.9, build c2ea9bc

kafka-exporter 二进制包的版本：
kafka_exporter-1.3.1.linux-amd64.tar.gz

docker-compose.yml 文件：
testkafka:
image: kafka_exporter:latest
command:

• ‘–kafka.server=x.x.x.x:9092’
• ‘–kafka.server=x.x.x.x:9092’
• ‘–kafka.server=x.x.x.x:9092’
• ‘–kafka.server=x.x.x.x:9092’
• ‘–kafka.server=x.x.x.x:9092’
  restart: always
  ports:
• “9318:9308”

kafka-exporter.json
[
{
“targets”: [
“x.x.x.x:9318”
],
“labels”: {
“cluster”: “testkafka”,
“judian”: “xxxxxxxxxxx”,
“service”: “testkafka”
}
}
]

prometheus.yml 配置

• job_name: ‘kafka_exporter’
  honor_labels: true
  scrape_interval: 1m
  scrape_timeout: 1m
  metrics_path: ‘/metrics’
  scheme: http
  file_sd_configs:
  • files:
    • ‘config/kafka_exporter.json’
      refresh_interval: 10m

使用二进制包构建镜像以后，使用./docker-compose up -d 可以启动容器
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c6edf96b0f04 kafka_exporter:latest “./kafka_exporter –…” 2 hours ago Up 2 hours 0.0.0.0:9318->9308/tcp, :::9318->9308/tcp testkafka_1

2. 问题描述？#

但是在 prometheus 监控到到实例也是 down 的状态

并且访问界面得到的报错为：
curl -kv x.x.x.x:9318/metrics

• Trying x.x.x.x:9318…
• Connected to x.x.x.x (x.x.x.x) port 9318 (#0)
