## 实现功能
### Consul Manager
- 更名Consul Manager
- 增加Consul Web管理功能
- 增加Consul服务器的状态查看
- 支持Consul Services的增删改查
- 支持批量删除Service功能
- 优化了对Tags、Meta、健康检查的配置管理
### Blackbox Manager
- 基于Prometheus + Blackbox_Exporter实现站点与接口监控。
- 基于Consul实现Prometheus监控目标的自动发现。

## 部署说明
### 1. 部署Consul
##### 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
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
}
```
##### 启动与鉴权配置
```bash
systemctl enable consul.service
systemctl start consul.service
# 获取登录密码
consul acl bootstrap
# 记录 SecretID
```
### 2. 部署Consul Manager
##### 使用docker-compose来部署
编辑docker-compose.yaml文件修改传入的3个环境变量
- **consul的`token`consul的`URL`(/v1要保留)登录Consul Manager的`密码`**
- 启动:`docker-compose up -d`
- 访问:`http://{IP}:1026`
---
# 如何优雅的使用Consul管理Blackbox站点监控
##### 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
- **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
##### 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。
- 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jobmodule与consul的tags**
参考配置2XX4XXTCP类型的监控注意JOB名称不要与已有的重复。
```yaml
vi prometheus.yml

### 配置Blackbox_Exporter
参考配置2XX4XXTCP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
- 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。
