从命令行添加Azure Application Insights状态监视器

Question

http://azure.microsoft.com/en-us/documentation/articles/app-insights-monitor-performance-live-website-now/

我有几个站点托管在azure上的VM上，该VM与云服务Webroles一起部署。

有人见过从代码或命令行安装状态监视器的例子吗？目标是自动将IIS站点添加到Azure App Insight中，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，该脚本应该插入到现有的安装VS在线应用Insights的方法中。

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
[Environment]::SetEnvironmentVariable("InstalledStatusMonitor", "1", "Machine")

Write-Host "Installation complete" -ForegroundColor Green

我在这里写了一篇关于它的博客文章，所以如果我们遇到了问题，而我忘了更新这篇文章，你应该可以在那里看到更新。

多亏了pksorensen提供的直接链接，Web平台安装程序从这里下载包。我对此做了更多的工作，现在有了一个完全自动化的过程。我有一个示例存储库可用在这里与一个工作项目…这个提交应该描述您需要对您自己的web项目做什么，以使状态监视器在web角色上工作。

Sergey Kanzhelev的一篇文章表明，对工人角色也应该可以这样做。

下面是所需的各个步骤。我会尝试提供一个关于非Web角色的更新，如果我有机会研究它：

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。

@echo off

if "%EMULATED%"=="true" goto :EndOfScript

:: Set appropriate execution policy on the host machine
set ExecutionPolicyLevel=RemoteSigned
for /F "usebackq" %%i in (`powershell -noprofile -command "Get-ExecutionPolicy"`) do (
    set ExecutionPolicy=%%i
    if /I "%%i"=="Unrestricted" goto :AllIsWell
    if /I "%%i"=="RemoteSigned" goto :AllIsWell
    Powershell.exe -NoProfile -Command "Set-ExecutionPolicy RemoteSigned" < NUL >> NUL 2>> NUL
)

:AllIsWell

Powershell.exe -NoProfile -Command "& '%~dp0InstallStatusMonitor.ps1'" < NUL  >> NUL 2>> NUL
echo "done" >"%ROLEROOT%\startup.task.done.sem"

:EndOfScript

exit 0

与bootstrap.bat文件一样，设置属性以将该文件也复制到输出目录。这是先前发布的脚本的更新版本

如果您需要添加要跟踪的自定义属性的功能，例如能够根据角色名称或角色实例区分依赖关系，那么您需要在文档中描述的之前进入pipleline的应用程序洞察。

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,而是将其添加到ApplicationInsights.config文件：

<?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>
