我在使用Cloud Service Webroles部署的Azure上的VM上托管了一些站点。

有谁见过从代码或命令行安装状态监视器的例子?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,该脚本应插入现有的安装VS Online App 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

我在这里写了一篇关于它的博客文章,所以如果我们遇到问题并忘记更新这篇文章你应该能够在那里看到更新。

感谢pksorensen的直接链接,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。我有一个样本存储库,这里有一个工作项目。此提交应描述您需要对自己的Web项目执行的操作,以使Status Monitor在Web角色上工作。

Sergey Kanzhelev发表了一篇文章,指出应该可以对工人角色这样做。

以下是所需的各个步骤。如果我有机会研究它,我将尝试提供非Web角色的更新:

1. ServiceDefinition.csdef

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>

2. WebProject / Role_Start / Bootstrap.bat

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。

:: The scripts can be downloaded directly from
:: http://go.microsoft.com/fwlink/?LinkID=329971

@echo off

:: Do not attempt to install the agent on an emulated environment
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

3. WebProject / Role_Start / InstallStatusMonitor.ps1

与Bootstrap.bat文件一样,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,则需要比文档中描述的更早进入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值设定项。

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>

在我的IAAS模型中,我引用了这些脚本进行设置,在安装和重新启动IIS之前,它还使用直接msi URL而不是Web Platform。

我使用PowerShell DSC和某种蓝绿色IIS重置,因此没有中断,因此服务器可以配置状态监视器作为初始配置的一部分,应用程序代码可以驱动遥测。

Package AppInsights
     {                             

        Ensure      = "Present"  
        Path        = "E:\dsc\ApplicationInsightsAgent.msi" # copied at some vm location
        Name        = "Application Insights Status Monitor"
        ProductID   =  "CBF2C62C-9537-4D8E-9754-92E54A0822D4"                       
    }

如果您的web.config没有检测密钥,则可以使用以下内容在安装后的DSC中启用您的网站。

Import-Module 'C:\Program Files\Microsoft Application Insights\Status Monitor\PowerShell\Microsoft.Diagnostics.Agent.StatusMonitor.PowerShell.dll'
Start-ApplicationInsightsMonitoring -Name 'your web site' -InstrumentationKey '<KeyHere>'
