我已经设置了 NLog 来与 Applicatin Insights 配合使用,还记录 js 异常,并且正在按要求工作。但是,我正在努力使仪器密钥动态化,以便它针对特定于环境的应用程序洞察实例。
NLog 配置目标

如何在上述场景中使检测密钥动态化?
检测密钥可以设置为动态,以便它针对特定于环境的应用程序洞察实例,如下所示。
const config = require('config');
const appInsights = require('applicationinsights');
// Determine the environment (development, production, etc.)
const environment = process.env.NODE_ENV || 'development';
// Get the instrumentation key from the configuration based on the environment
const instrumentationKey = config.get('appInsightsInstrumentationKey');
// Initialize Application Insights with the dynamic instrumentation key
appInsights
.setup(instrumentationKey)
.start();
npm install applicationinsights config
mkdir 配置config
目录来存储特定于环境的配置文件。mkdir config
配置应用程序洞察
在 Azure 门户中,创建 Application Insights 资源(如果尚未创建)。您需要此资源的检测密钥。
创建配置文件
在
config
目录中,创建两个配置文件:development.json
和production.json
。将 "YOUR_DEVELOPMENT_INSTRUMENTATION_KEY"
和 "YOUR_PRODUCTION_INSTRUMENTATION_KEY"
替换为您的实际仪器键。
development.json
{
"appInsightsInstrumentationKey_development": "key "
}
set NODE_ENV=development
并运行代码
