# 概述
3 years ago
- ConsulManager是一个使用Flask+Vue开发的Consul WEB管理工具比官方自带的WEB UI实现了更多的功能可以方便的对Consul Services进行增删改查支持批量操作并优化了对Tags、Meta、健康检查的配置管理与查询展示。
- 本工具还针对使用Consul+Prometheus+Blackbox_Exporter实现站点与接口监控的应用场景制作了一个单独的管理页面并提供了站点与接口监控的完整方案。
- 本工具支持使用docker-compose快速部署并提供批量导入服务到Consul的脚本。

### 1. 部署Consul
3 years ago
##### 安装
```bash
# 使用yum部署consul
yum install -y yum-utils
yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
yum -y install consul
# 或者直接下RPM包安装
wget https://rpm.releases.hashicorp.com/RHEL/7/x86_64/stable/consul-1.11.1-1.x86_64.rpm
rpm -ivh ./consul-1.11.1-1.x86_64.rpm
```
##### 配置
```bash
vi /etc/consul.d/consul.hcl
3 years ago
advertise_addr = "10.5.148.67" #如果有多网卡需要配置这行填写你的网卡IP
3 years ago
data_dir = "/opt/consul"
client_addr = "0.0.0.0"
ui_config{
enabled = true
}
server = true
bootstrap = true
acl = {
enabled = true
default_policy = "deny"
enable_token_persistence = true
}
```

# 获取登录密码
consul acl bootstrap
# 记录 SecretID
```

# 应用场景如何优雅的使用Consul管理Blackbox站点监控
3 years ago
##### Consul字段设计说明
3 years ago
- 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。
3 years ago
- 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
3 years ago
- **前5个字段合并即为consul的serviceID作为唯一监控项标识**
3 years ago
- **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。**
3 years ago
### 配置Prometheus
##### 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。
- 把Consul每个service的Meta的KV关联到Prometheus每个指标的标签。
3 years ago
- 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。
3 years ago
3 years ago
**以下配置的同一个job的`job_name``module``tags`使用同一命名关联jobmodule与consul的tags**
3 years ago
参考配置2XX4XXTCP类型的监控注意JOB名称不要与已有的重复。

```
### 批量导入脚本
3 years ago
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
- 支持Grafana 8基于blackbox_exporter 0.19.0设计
- 采用图表+曲线图方式展示TCPICMPHTTPS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。
