Prometheus之自定义标签

前言：

我们一般通过grafana导入Dashboard模板用来展示数据，但是有时候需要自己定义展示项目，这时需要自己在Prometheus重新自定义标签，并在grafana进行应用。

1、Prometheus标签重命名

[root@prome-01 prometheus]# pwd
/opt/prometheus

[root@prome-01 prometheus]# cat prometheus.yml
# 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).

remote_write:
  - url: http://192.66.255.120:8428/api/v1/write

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['192.66.255.120:9093']

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
  - "/opt/rules/*_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
#  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

  - job_name: 'prometheus-server'
    file_sd_configs:
    - refresh_interval: 1m
      files:
      - targets/server.yml
    relabel_configs:
      - source_labels: [__address__]
        target_label: instance
        regex: (.*):(.*)
        replacement: $1
        action: replace

  - job_name: 'Linux'
    file_sd_configs:
    - refresh_interval: 1m
      files:
      - targets/linux.json

2、在target yml文件中定义标签

[root@prome-01 prometheus]# cat targets/server.yml
- targets: [ '192.66.255.120:9100' ]
  labels: {'ProjectName': '用户中心-生产', 'TargetName': '普罗米修斯服务端', 'Zone': 'ZZW'}

3、grafana利用自定义标签定义展示项目

• 点击服务器资源总览表右上角三个点
  
  
• 点击编辑
  
  
• 进入编辑界面，点击Transform data(转换数据)
  
  
• 点击Filter fields by name，选择TargetName标签，此标签是在prometheus yml文件中定义的标签，会自动加载过来。
  
  
• 给标签命名
