## README

### 请求公网地址，数据打入到 prometheus, grafana展示
### python编写exporter监控接口访问数量+错误率+响应时间

```angular2html
yum install gcc gcc-c++ git libyaml-devel zlib-devel bzip2-devel pcre-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel python3-devel.x86_64 python-devel.x86_64 libcurl-devel -y

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r  requirements.txt
```

###修改配置文件增加数据收集 
vi prometheus.yml   然后再grafana上配置数据源
```angular2html
# 增加监听的 IP 端口，稍后用Python起一个http服务
 - job_name: 'business_data_panel_monitor'
    scrape_interval: 60s
    metrics_path: /metrics
    static_configs:
      - targets: ['180.76.52.138:9521']
~                                   
```
修改玩配置文件，重新加载
```angular2html
curl -XPOST http://127.0.0.1:9090/-/reload
```
```angular2html
 pip3 uninstall pycurl
Cannot uninstall requirement pycurl, not installed
[root@ecs-prod-prometheus-arch-0006 website_monitor]# export PYCURL_SSL_LIBRARY=nss
[root@ecs-prod-prometheus-arch-0006 website_monitor]# pip3 install pycurl

```

###显示期望时间的比例，比如只显示小于1秒，占总次数的比例
```
delta(url_http_request_time_total{le='1'}[1m]) / on(url) group_left delta(http_request_total[1m])
```
###http code的每分钟增长率，如果出现5xx，就说明有问题了
```angular2html
Metrics    irate(url_http_code_total[1m])
Legend    {{url}}:{{code}}
```

```angular2html
curl -XPOST http://10.94.12.250:9090/-/reload
curl -X POST -g 'http://xxx.com/prometheus/api/v1/admin/tsdb/delete_series?match[]={wanip="12.0.0.1:9085"}
```
