监控传统服务器

# 1. 简介

DeepFlow 支持监控传统服务器。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. 配置 DeepFlow Server

# 3.1 更新 deepflow-server 配置

检查服务器所有的网段是否在以下网段列表中

local_ip_ranges:
- 10.0.0.0/8
- 172.16.0.0/12
- 192.168.0.0/16
- 169.254.0.0/15
- 224.0.0.0-240.255.255.255

若不在，需要在下面自定义配置文件内 local_ip_ranges 列表中添加缺失的服务器网段。

修改 values-custom.yaml 自定义配置文件：

# add
configmap:
  server.yaml:
    controller:
      genesis:
        local_ip_ranges:
        - 10.0.0.0/8
        - 172.16.0.0/12
        - 192.168.0.0/16
        - 169.254.0.0/15
        - 224.0.0.0-240.255.255.255
        # - 7.8.0.0/16  # FIXME: your host all network cidr
      trisolaris:

更新 deepflow

helm upgrade deepflow -n deepflow -f values-custom.yaml deepflow/deepflow
## Restart deepflow-server
kubectl delete pods -n deepflow -l app=deepflow -l component=deepflow-server

deepflow-ctl agent-group create $AGENT_GROUP
deepflow-ctl agent-group list $AGENT_GROUP # Get agent-group ID

# 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：
