I have a few sites hosted on a VM on azure that is deployed with Cloud Service Webroles.
Have anyone seen examples of installing the status monitor from code or command line? Goal is to add IIS sites automaticly to Azure App Insight without logging into remote desktop as shown in the link above.

We ran into this issue also and wrote a script, which should plug into 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

I wrote a blog post about it here, so if we run into issues and I forget to update this post you should be able to see updates there.
Update 1
Thanks to pksorensen for the direct link, it looks like this is where the Web Platform installer downloads the package from. I've done some more with this and now have a fully automated process working. 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, indicating that it should be possible to do this to worker roles too.
Here are the individual steps required. I will try to provide an update on non-web roles if I get a chance to look into it:
1. ServiceDefinition.csdef
Add the following Startup entry into your web deployment project, it will run when the role is being created or deployed to.
<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
This is the batch file called by the startup task. It has to be placed in your web project. Set the properties to always copy the file to output directory.

:: The scripts can be downloaded directly from

@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
Like the Bootstrap.bat file, set the properties to copy this file to the output directory also. This is an updated version of the script posted earlier

Update 2
If you need the capability to add custom properties to track on, such as being able to discriminate dependencies based on role names or role instances you need to get into the Application Insights pipleline earlier than is described in the documentation.
Let's say you want to be able to filter on Role Name and Role Instance Id, you would create a custom context initializer.
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;
}
}
}
}
but instead of plugging it in in code, you would instead add it to the ApplicationInsights.config file:
<?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>
回答2:
In my IAAS model, I referenced these scripts to set it up, it also uses the direct msi URL as opposed to Web Platform, before installation and restarts IIS.
I used PowerShell DSC for this and some sort of blue-green IIS resets so there are no outages, so servers could be configured with Status monitor as a part of initial provisioning and the application code could drive the telemetry.
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"
}
If your web.config doesn't have the instrumentation key, you may use below to enable for your website in your DSC, post installation.
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>'
