1. 配置文件
参考alluxio官方文档:https://docs.alluxio.io/ee/user/stable/en/deploy/Running-Alluxio-On-Docker.html
使用用户自定义网络的方式。Docker Compose配置文件docker-compose.yaml:
version: '3'
services:
alluxio-master:
image: alluxio/alluxio:2.4.1
ports:
- "19999:19999"
- "19998:19998"
volumes:
- {{localPath}}:/opt/alluxio/underFSStorage
environment:
ALLUXIO_JAVA_OPTS: " -Dalluxio.master.hostname=alluxio-master -Dalluxio.master.mount.table.root.ufs=/opt/alluxio/underFSStorage"
command: master
networks:
- alluxio_network
alluxio-worker:
image: alluxio/alluxio:2.4.1
ports:
- "29999:29999"
- "30000:30000"
shm_size: "1gb"
volumes:
- {{localPath}}:/opt/alluxio/underFSStorage
environment:
ALLUXIO_JAVA_OPTS: " -Dalluxio.worker.ramdisk.size=1G -Dalluxio.master.hostname=alluxio-master -Dalluxio.worker.hostname=alluxio-worker"
command: worker
networks:
- alluxio_network
grafana:
image: grafana/grafana:latest
ports:
- "3000:3000"
networks:
- alluxio_network
prom:
image: prom/prometheus:latest
ports:
- "9090:9090"
volumes:
- {{localPrometheusConfigDir}}:/etc/prometheus
networks:
- alluxio_network
networks:
alluxio_network:
driver: "bridge"
其中:
{localPath}是alluxio本地的存储路径,需要根据自己情况进行设置。{localPrometheusConfigDir}指定了promethus配置文件所在目录的映射路径。
在{localPrometheusConfigDir}下,新建prometheus配置文件prometheus.yml,内容如下:
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
- job_name: 'alluxio master'
metrics_path: '/metrics/prometheus/'
static_configs:
- targets: ['alluxio-master:19999']
- job_name: 'alluxio worker'
metrics_path: '/metrics/prometheus/'
static_configs:
- targets: ['alluxio-worker:30000']
需要注意scrape_config下的参数设置:
- 因为后面会使用
alluxio官方的grafana配置,里面默认的job_name是alluxio master和alluxio worker,所以这里也这样进行设置。 alluxio暴露prometheus度量指标的路径是/metrics/prometheus/,并不是默认的/metrics/targets根据docker-compose.yaml中的设置进行设置的,对应alluxio的服务地址。
2. Grafana配置
在docker-compose.yaml文件所在路径下,执行docker-compose up -d,即可启动所需的服务。
浏览器访问: http://localhost:3000/,可以看到grafana的界面,默认用户密码admin:admin。
2.1 配置prometheus数据源
configuration->Data Sources->Add data source

根据之前docker-compose.yaml文件中的设置,设置prometheus的服务访问url。
其他设置可以不动,点一下test and save,确保可以访问到。

这样,grafana的数据源就配置好了。
2.2 导入alluxio官方看板
参考:https://grafana.com/grafana/dashboards/13467
alluxio官方给定的看板配置序号是13467。
操作路径: Dashboards->manage->import

指定序号,然后导入
返回dashboard的home路径,即可看到alluxio的看板:
