普罗米修斯监控openGauss

''' 功能描述：在benchmarksql工具测试过程的输出信息通过tee命令 固定输出到/tmp/tpcc.log（便于在不同环境上部署），采集函数从/tmp/tpcc.log文件获取到tpmC值，发送函数将值发送到pushgateway服务。 '''

prometheus.yml 文件配置参考
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: ['prometheus_ip:9090']

  - job_name: 'pushgateway'
