我在使用Cloud Service Webroles部署的Azure上的VM上托管了一些站点。
有没有人看过从代码或命令行安装状态监视器的示例？目标是自动将IIS站点添加到Azure App Insight，而无需登录到远程桌面，如上面的链接所示。

我们也遇到了这个问题并编写了一个脚本，该脚本应插入the existing method for installing VS Online App Insights。
if(${env:InstalledStatusMonitor} -eq 1)
{
Write-Host "Status monitor has already been installed on this machine by this script" -ForegroundColor Green
}
Write-Host "Using chocolatey to install the Web Platform Installer ..." -ForegroundColor Green
iex ((new-object net.webclient).downloadstring('https://chocolatey.org/install.ps1'))
cinst webpi -y
Stop-Process -Name WebPlatformInstaller
Write-Host "Using Web Platform Installer to install Status Monitor ..." -ForegroundColor Green
&"$env:ProgramFiles\Microsoft\Web Platform Installer\WebpiCmd.exe" /Install /AcceptEula /Products:ApplicationInsightsStatusMonitor
Write-Host "Adding app pool account to the 'Performance Monitor Users' local group" -ForegroundColor Green
$group = "Performance Monitor Users"
$user = "Network Service"
$computer = $(Get-WmiObject Win32_Computersystem).name
$de = [ADSI]"WinNT://$computer/$group,group"
$de.psbase.Invoke("Add",([ADSI]"WinNT://$user").path)
Write-Host "Waiting 30 seconds for Status Monitor to finish its install ..." -ForegroundColor Green
Start-Sleep -Seconds 30
Write-Host "Stop-Starting services to enable tracing..." -ForegroundColor Green
# For some reason, even though Status Monitor calls "iisreset.exe /restart"
# calling it here leaves IIS and website stopped.
&iisreset.exe /restart
Write-Host "waiting a few seconds..." -ForegroundColor Yellow
Start-Sleep -Seconds 2
Write-Host "starting..." -ForegroundColor Yellow
Start-Service -Name W3SVC
Get-WebApplication | Select ApplicationPool -Unique | %{ Start-WebAppPool $_.applicationPool }
Get-Website | Start-Website
Write-Host "started" -ForegroundColor Yellow
Write-Host "Cleaning up running applications" -ForegroundColor Green
Stop-Process -Name Microsoft.Diagnostics.Agent.StatusMonitor
Write-Host "Setting environment variable to indicate status monitor has been installed" -ForegroundColor Green

Write-Host "Installation complete" -ForegroundColor Green
I wrote a blog post about it here，如果我们遇到问题并且忘记更新此帖子，您应该可以在那里看到更新。
感谢pksorensen提供直接链接，看起来这就是Web平台安装程序从中下载软件包的地方。我已经完成了更多工作，现在有一个完全自动化的流程。 I have a sample repository available here with a working project.。 This commit should describe what you need to do to your own web project to get Status Monitor working on a Web Role.
There is a post by Sergey Kanzhelev，表示应该可以对工作人员角色执行此操作。
以下是所需的各个步骤。如果我有机会研究它，我会尝试提供非网络角色的更新：
将以下启动条目添加到Web部署项目中，它将在创建或部署角色时运行。
<ServiceDefinition>
<WebRole>
...
<Startup>
<Task commandLine="Role_Start\Bootstrap.bat" executionContext="elevated" taskType="simple">
<Environment>
<Variable name="EMULATED">
<RoleInstanceValue xpath="/RoleEnvironment/Deployment/@emulated" />
</Variable>
</Environment>
</Task>
</Startup>
</WebRole>
</ServiceDefinition>
这是启动任务调用的批处理文件。它必须放在您的Web项目中。将属性设置为始终将文件复制到输出目录。

与Bootstrap.bat文件类似，设置属性以将此文件复制到输出目录。这是之前发布的脚本的更新版本

如果您需要能够添加自定义属性以进行跟踪，例如能够根据角色名称或角色实例区分依赖关系，则需要在文档中描述之前进入Application Insights pipleline。
假设您希望能够过滤角色名称和角色实例ID，您可以创建自定义上下文初始化程序。
using System.Text.RegularExpressions;
using Microsoft.ApplicationInsights.DataContracts;
using Microsoft.WindowsAzure.ServiceRuntime;
namespace Utilities
{
public class AppInsightsCurrentRoleIdAsTagInitializer : Microsoft.ApplicationInsights.Extensibility.IContextInitializer
{
public void Initialize(TelemetryContext context)
{
context.Properties["Greenfinch - RoleName"] = RoleEnvironment.CurrentRoleInstance.Role.Name;
context.Properties["Greenfinch - RoleInstanceId"] = InstanceId;
}
private string InstanceId
{
get
{
var instanceId = Regex.Match(RoleEnvironment.CurrentRoleInstance.Id, "\\d+$", RegexOptions.Compiled).Value;
return string.IsNullOrWhiteSpace(instanceId)
? "unable to get instance id"
: instanceId;
}
}
}
}
但不是将其插入代码中，而是将其添加到ApplicationInsights.config文件中：
<?xml version="1.0" encoding="utf-8"?>
<ApplicationInsights xmlns="http://schemas.microsoft.com/ApplicationInsights/2013/Settings" schemaVersion="2014-05-30">
...
<ContextInitializers>
...
<Add Type="Utilities.AppInsightsCurrentRoleIdAsTagInitializer, Utilities" />
</ContextInitializers>
...
</ApplicationInsights>
