##### Consul字段设计说明
|
||||
### Consul字段设计说明
|
||||
|
||||
- 所有数据存在一个名为`blackbox_exporter`的Services项中,每个监控目标为一个子Service。
|
||||
- 每个Service包含一个Tag,会自动配置为meta中的`module`的值,作为Prometheus自动发现的tags。
|
||||
- 每个Service使用Meta的kv保存监控目标的明细:`module`,`company`,`project`,`env`,`name`,`instance`,分别表示:监控类型,公司部门,项目,环境,名称,实例url
|
||||
- 每个Service使用Meta的kv保存监控目标的属性:`module`,`company`,`project`,`env`,`name`,`instance`,分别表示:监控类型,公司部门,项目,环境,名称,实例url。
|
||||
- **新增监控时,监控类型字段(`module`)和Blackbox配置中的`module`必须保持一致。**
|
||||
- **前5个字段合并即为consul的serviceID,作为唯一监控项标识**
|
||||
- **建议监控类型字段:`meta内的module`,`blackbox-exporter配置中的module`及`Prometheus的job名`使用同一命名。**
|
||||
|
||||
### 配置Prometheus
|
||||
### 配置Prometheus与Blackbox
|

|
||||
##### 基于Consul实现Prometheus的自动发现功能配置
|
||||
|
||||
- 根据Consul每个service的tag来把监控目标关联到Prometheus的JOB。
|
||||
#### 基于Consul实现Prometheus的自动发现功能配置
|
||||
- 把Consul每个service的Meta的KV关联到Prometheus每个指标的标签。
|
||||
- 根据每个指标的标签来对监控目标分类,分组,方便管理维护。
|
||||
|
||||
**以下配置的同一个job的`job_name`,`module`,`tags`使用同一命名,关联job,module与consul的tags**
|
||||
|
||||
参考配置:2XX,4XX,TCP类型的监控,注意JOB名称不要与已有的重复。

|

|
||||
### 配置Blackbox_Exporter
|
||||
|
||||
参考配置:2XX,4XX,TCP类型的监控,注意模块名称不要与已有的重复。
|
||||
|
||||
```
|
||||
cat blackbox.yml
|
||||
modules:
|
||||
http_2xx:
|
||||
prober: http
|
||||
http:
|
||||
valid_status_codes:
|
||||
- 200
|
||||
- 301
|
||||
- 302
|
||||
- 303
|
||||
no_follow_redirects: true
|
||||
preferred_ip_protocol: ip4
|
||||
ip_protocol_fallback: false
|
||||
|
||||
http_4xx:
|
||||
prober: http
|
||||
http:
|
||||
valid_status_codes:
|
||||
- 401
|
||||
- 403
|
||||
- 404
|
||||
preferred_ip_protocol: ip4
|
||||
ip_protocol_fallback: false
|
||||
|
||||
tcp_connect:
|
||||
prober: tcp
|
||||
```
|
||||
|
||||
### 批量导入脚本
|
||||
|
||||
在units目录下`instance.list`中写入监控目标的信息:JOB名称,公司/部门,项目,环境,名称,实例url,每行一个,空格分隔。
|
||||
**注意:前5个字段组合起来必须唯一,作为一个监控项的ID。**
|
||||
修改units目录下导入脚本中的consul_token和consul_url,保存后执行input.py,即可导入所有监控目标到Consul,并符合Prometheus的自动发现配置。
|
||||
|
||||
### 导入Blackbox Exporter Dashboard
|
||||
|
||||
##### 1. 配置Blackbox_Exporter
|
||||
- 在Web页面点击`Blackbox 站点监控/Blackbox 配置`,点击`复制配置`。
|
||||
- 编辑blackbox_exporter的`blackbox.yml`,清空已有的配置,把复制的内容粘贴进去,重启blackbox_exporter。
|
||||
##### 2. 配置Prometheus
|
||||
- 在Web页面点击`Blackbox 站点监控/Prometheus 配置`,点击`复制配置`。
|
||||
- 编辑Prometheus的`prometheus.yml`,把复制的内容追加到最后,reload或重启Prometheus。
|
||||
##### 3. 配置Prometheus告警规则
|
||||
- 在Web页面点击`Blackbox 站点监控/告警规则`,点击`复制配置`。
|
||||
- 编辑Prometheus的`rules.yml`,把复制的内容追加到最后,reload或重启Prometheus。
|
||||
##### 4. 导入Blackbox Exporter Dashboard
|
||||
- 支持Grafana 8,基于blackbox_exporter 0.19.0设计
|
||||
- 采用图表+曲线图方式展示TCP,ICMP,HTTPS的服务状态,各阶段请求延时,HTTPS证书信息等
|
||||
- 优化展示效果,支持监控目标的分组、分类级联展示,多服务同时对比展示。
|
||||
|
||||
```
|
||||
导入ID:9965
|
||||
详细URL:https://grafana.com/grafana/dashboards/9965
