我们需要关注的主要文件

data                              为数据目录

prometheus                 为程序二进制文件

prometheus.ym            为prometheus主配置文件

1) data目录

01****    开头的这些文件为历史数据文件目录

wal         数据保护文件目录,prometheus为了防止数据的突然断电等情况,如果出现断电状况恢复后wal下的文件会恢复到内存中

2) 主配置文件

[root@aliyun-hk-yabo-prod-jiranew prometheus210]# 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).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
       - 127.0.0.1:9093

# 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:
  # 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'.

    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'jira-xxxxxx'          
    static_configs:
      - targets: ['IP:9100']     
        labels: 
          instance: jira-old


注:prometheus服务器默认监听端口为9090 ,client端默认监听9100
