prometheus 安装和简单使用

一 ： 安装

环境准备：1 go1.12及以上

                  2 git

mkdir -p $GOPATH/src/github.com/prometheus
cd $GOPATH/src/github.com/prometheus
git clone https://github.com/prometheus/prometheus.git
cd prometheus
make build （此步可能持续较长时间，耐心等待）

准备配置文件

vi prometheus.yml

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

# 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=` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

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