监控云服务器

# 1. 简介

DeepFlow 支持监控云服务器,并通过调用云厂商 API 获取云资源信息,自动注入到所有观测数据中(AutoTagging)。 注意 DeepFlow Server 必须运行在 K8s 之上,如果你没有 K8s 集群,可参考 All-in-One 快速部署章节先部署 DeepFlow Server。

# 2. 部署拓扑

# 3. 创建公有云 Domain

DeepFlow 目前支持如下公有云的资源信息同步(标记为 TBD 的正在整理代码中):

云服务商(英文) 云服务商(中文) DeepFlow中使用的类型标识
AWS AWS aws
Aliyun 阿里云 aliyun
Baidu Cloud 百度云 baidu_bce
Huawei Cloud 华为云 huawei
Microsoft Azure 微软云 TBD
QingCloud 青云 qingcloud
Tencent Cloud 腾讯云 tencent

可通过 deepflow-ctl domain example <domain_type> 命令获取创建公有云 Domain 的配置文件模板。 以阿里云为例:

deepflow-ctl domain example aliyun > aliyun.yaml
1

修改配置文件 aliyun.yaml,填写 AK/SK(需要云资源的只读权限)和资源所在的 Region 信息:

name: aliyun
type: aliyun
config:
  # AccessKey Id
  secret_id: xxxxxxxx ## FIXME: your secret_id
  # AccessKey Secret
  secret_key: xxxxxxx ## FIXME: your secret_key
  include_regions: 华北2(北京) ## The region where deepflow is docked, if it is empty, it means all regions, and the regions are separated by commas

使用修改好的配置文件创建公有云 Domain:

deepflow-ctl domain create -f aliyun.yaml

# 4. 部署 DeepFlow Agent

注意

若 deepflow-agent 因缺少依赖库无法正常启动可下载静态链接编译的 deepflow-agent, 注意静态链接编译的 deepflow-agent 在多线程下有严重的性能问题:
