背景
部分客户系统采用的是.NET 4.5 部署研发的、基于 IIS 进行发布的 Web 项目，需要接入到观测云进行链路信息展示，ddtrace 和 otel 对于低版本.NET 支持力度有限。
环境信息
- IIS 4.0
- .NET core 4.0、4.5、4.6
- Window Server 2012 R2
域名配置
准备一个域名 www.datakit.com，需要申请 https 证书
配置 host
修改 hosts 文件，添加两个域名
127.0.0.1 www.google.com
127.0.0.1 www.datakit.com
www.google.com： NewRelic Agent 在生效前需要去访问一下 google，目的是确保网络通畅www.datakit.com： NewRelic Agent 上报链路数据采用的是tls，需要一个域名和证书信息
域名生效
在 IIS 下新增网站，域名为 www.google.com，端口为 80。
根证书配置
如果申请的 https 证书是购买的，一般不需要配置根证书，如果属于自签证书，则需要配置。
NewRelic 接入
经调查研究表明，NewRelic .NET Agent 版本 6.27 可用于当前客户环境，采集链路并上报数据到观测云（DataKit采集上报）进行统一的信息展示。
下载安装 .NET Agent
安装前需要准备一个 NewRelic license，安装时需要用到，可以随意填写，也可以填写固定值eu01xx332b83865e13171131e7f9e08dFFFFNRAL
安装完成后有两个目录
-
C:\Program Files\New Relic\.NET Agent -
C:\ProgramData\New Relic\.NET Agent
其中 C:\Program Files\New Relic\.NET Agent 目录下有个 newrelic.conf 文件，采集.NET 信息需要。
IIS 下 NewRelic 配置
使用管理员权限打开 PowerShell，执行以下命令
$env:COR_ENABLE_PROFILING=1;
$env:COR_PROFILER={71DA0A04-7777-4EC6-9643-7D28B46A8A41};
$env:NEWRELIC_INSTALL_PATH="C:\Program Files\New Relic\.NET Agent";
$env:NEW_RELIC_HOST="www.datakit.com";
在 PowerShell 使用 Get-ChildItem env:查看命令是否生效，该命令会列出当前系统的所有环境变量信息
DataKit 安装&配置
安装
参考安装文档
DataKit 的安装目录为 C:\Program Files\datakit
调整 DataKit 配置
DataKit 全局配置文件为datakit.conf，这里需要调整datakit.conf，让其至此 tls：
[http_api]
rum_origin_ip_header = "X-Forwarded-For"
listen = "0.0.0.0:9529"
disable_404page = false
rum_app_id_white_list = []
public_apis = []
timeout = "30s"
close_idle_connection = false
[http_api.tls]
cert="/cert/cmyncp.com_cert.pem"
privkey="/cert/cmyncp.com_key.pem"
其中 [http_api.tls] 为开启 tls 模块
- cert：域名公钥证书
- privkey：域名私钥证书
路径建议填写绝对路径，否则可能会出现意想不到的效果
开启 NewRelic 采集器
进入 DataKit 安装目录下，并进入 conf.d/newrelic，复制 newrelic.config.sample 为 newrelic.config
重启 DataKit
在 PowerShell 下执行一下命令
datakit service -R
应用接入 NewRelic .NET Agent
配置 newrelic.conf

log： 日志信息
其中 host 和 port可以通过全局变量的方式进行配置
$env:NEW_RELIC_HOST="www.datakit.com";
$env:NEW_RELIC_PORT=9529;
重启 IIS
net stop /y was # stop iis
net start w3svc # start iis
访问应用
只有访问了应用，系统才会生成链路数据，并进行数据上报。
