Tons of statistics and metrics for Microsoft Azure websites (not only Asp.Net)

Labels: , , , , , , , ,
Your website is finally online. That great, good job. But now, you have a lot of questions: How much visits do I have? Which part of the site is mostly visited? Does the site performs well? In this post, I will show you some tools that exist in Microsoft Azure that will help you to get some answers.

Request and Error

When you create a website in Azure, you automatically got some monitoring. Go on portal.azure.com (the preview portal), and select your website.

Monitoring_2015-03-05_1540

This will be useful to see how many requests and errors you got. You could create some alerts, by clicking the "+" sign, and you would be notified by e-mail if the number of request is greater than x, over the last hour.

Analytics

The first time you will click on this section all the instruction will be given to you.
To collect end-user usage analytics about your application, insert the following script into each page you want to track. Place this code immediately before the closing </headtag, and before any other scripts. Your first data will appear automatically in just a few seconds.
To get analytics for the whole web site, in an Asp.Net MVC site, a good place will be: \Views\Shared\_Layout.cshtml.

In a Ghost blog, if you are using the default theme, the file will be /content/themes/casper/default.hbs. Otherwise, just replace "casper" by your theme name in the path.

Once your website is re-deployed, re-open the website blade and click again on the Analytics graph. And you will be able to see a lot of information: Session per browser, information on page's views, slowest pages, details on sessions, etc.


Analitics_tour


When you click on a graph, the Metrics Explorer blade will be visible. On the top of this blade, you will have many different options to customize your results. You will be able to add a chart, change the time range, add some filter and even set some alerts.


Metrics_explorer


Moreover, if you click on those Charts, tables or even on a row, you will have more details and options to fine-tune the result.


Diagnostics_Search


Application Insights

You thought it was enough? Well, Microsoft Azure still has one more tool for you, that will cover in this post: Application Insights. With this one, you will be able to see the health of your application by adding some tests, custom events, logs, errors, etc.
Adding Application Insights to your Asp.Net website, can easily be done via Visual Studio, like I explained in a previous post.

Since Azure is compatible with many different languages, chances are that you are using one of those. Let say you are running a node.js Ghost blog, how could you add Application Insights? By using website extensions. To add an extension you could use the Kudu interface. This interface is easy to access. In a browser, type the URL of the website but inject "scm" between the name of the application and the azurewebsites.net. Something like http://mybookmanager.scm.azurewebsites.net/


From_Kudu_Console2015-03-01_2044


Once you are in the Kudu interface, click on the tab Site Extensions, then section Gallery. Add the Application Insights Extension.
It's also possible to add a website extension using the website blade.


From_portal_2015-03-01_2101


This will gives you a lot of information already, but to add more customs metric in .Net by sure to add the Application Insights SDK to your porject. In node.js use the applicationinsights package from npm,

Four Simple Tips to Improve your Asp.Net MVC Project

Labels: , , , , , , , , ,
When it's time to do the re-factoring of a solution, it's always a good idea to clean the code before doing any re-factoring. In this post, I will share with you simple but very efficient ways to improve your solution.

1- Forget the magic string


By default in Asp.Net MVC magic strings are used every where.
return View("Index");
or
@Html.ActionLink("Delete Dinner", "Delete", "Dinners", new { id = Model.DinnerID }, null)

Nothing bad here, but nothing will tell you that to did a typo, or that the method name as changed. This is where T4MVC will become a great tool do add to all your project.

To add it a simple Nuget command is enough: Install-Package T4MVC. By doing this a T4 file (T4MVC.tt) will be added to your project that will generates a number of files. These generated files will simplify your life and gives you the opportunity to code using strongly type.

Here are few transformations:
// Before ----------------
  return View("Index");

// After with T4MVC
  return View(Views.Index);
An action link in a view.
// Before ----------------
  @Html.ActionLink("Delete Product", "Delete", "Products", new { id = Model.ProductID }, null)

// After with T4MVC
  @Html.ActionLink("Delete Product", MVC.Products.Delete(Model.ProductID))

An Ajax call.
// Before ----------------
<%= Ajax.ActionLink( "RSVP for this event",
                 "Register", "RSVP",
                 new { id=Model.DinnerID }, 
                 new AjaxOptions { UpdateTargetId="rsvpmsg", OnSuccess="AnimateRSVPMessage" }) %>

// After with T4MVC
<%= Ajax.ActionLink( "RSVP for this event",
                 MVC.RSVP.Register(Model.DinnerID),
                 new AjaxOptions { UpdateTargetId="rsvpmsg", OnSuccess="AnimateRSVPMessage" }) %>

A redirection.
// Before ----------------
return RedirectToAction("Details", new { id = product.ProductID });

// After with T4MVC
return RedirectToAction(MVC.Products.Details(product.ProductID));

When writing the code, it gives you intellisense where you normally would not have any. At compile time, it validates all the code so no typo or other misspelling errors are present.

2- Clean your views


You know all those "@using" on the top of each views that we copy over and over... It's time to remove them. The way to do it is by moving them to the web.config file in the "Views" folder.

web.config location

So you can move the namespaces used globally 
@using Microsoft.Security.Application
@using System.Globalization;

by including them to this section: 
<system.web.webPages.razor>
  <pages pageBaseType="System.Web.Mvc.WebViewPage">
    <namespaces>
      <add namespace="System.Web.Mvc" />
      <add namespace="System.Web.Mvc.Ajax" />

      <add namespace="Microsoft.Security.Application" />
      <add namespace="System.Globalization" />

    </namespaces>
  </pages>
</system.web.webPages.razor>

3- Don't lose time debugging


To many people are losing time debugging their application or web site. Start using Glimpse right away! This will provide information in real time across all layers of your application from the UI to the server and database side. Perfect to know everything that happen on a click of a button: javascript validation, controller code and even the query in the database.







Install it in ten seconds with the Nuget command manager and pick the version you need.

PM> Install-Package Glimpse



Glimpse is secure and is configured to be accessible only from localhost by default. But don't trust me and try it by yourself, or go check this one minute Glimpse Heads Up Display youtube video.

4- Start monitoring your website health and usage


Move your website on Microsoft Azure and use the Application Insights. This will gives you the opportunity to monitor that availability, performance and usage of your live application.

Add Application Insights


To add it you got many possibilities, one of them from Visual Studio 2013, just right-click on the project and select Add Application Insights Telemetry, and voilà!

Now you just need to run or deploy the website and after few minutes or so you will have plenty of information, graphs waiting for you in the Azure Portal.



Informations



You will find a lot of information about Application Insights on the Microsoft Azure


Wrapping up

I hope it will help you, thanks for reading. Any comments, suggestions and/or questions are welcome.

Upgrade an Application Windows Azure OS Family

Labels: , , , , , , , , , , , , , ,
Recently I add to upgrade an web site running in Azure Webrole from Azure OS famille 1.6 to a more recent version. While the migration was not complicated I encounter some little particularity that I found could be interesting to share.

The Context

The website was a Visual Studio 2010 project using Azure SDK 1.6 and a library call AspNetProvider that was part of Microsoft's sample few years ago to manage session and membership. Using the AspNetProvider library the session was saved in Azure blob storage, and the membership was saved in an SQL database.

The Goal

The application must stay a Visual Studio 2010 project, but using the most-recent Azure SDK and Azure Storage Client as possible.

The Solution

  • Azure SDK 2.1
  • Azure.StorageClient 4.0
  • Universal Provider version 2.1
  • OS famille 4

The Journey


Migration from SDK 1.6 to SDK 2.1


Azure SDK version 2.1 is the higher version compatible with Visual Studio 2010. And can be downloaded from Microsoft's website. Once it is installed, just open the project in Visual Studio and right-click on the Azure Project. By clicking on the upgrade button the magic will happen. Some errors could stay but the hard work will be done for you.


Migration from AspNetProvider to UniversalProvider


we need to remove all reference to the AspNetProvider library. Just expand the resources node in the Solution Explorer and delete the reference. One thing important is that since we are using Visual Studio 2010 the latest version of the UniversalProvider we can use is 1.2. More recent version are using .Net 4.5 and this is not compatible with the present solution. To get the reference added to the project just execute the following Nugget command:
Install-Package UniversalProvider -version 1.2

Check the web.config file to clean the membership connections.

Migration of the Azure Storage Client


This one is the easiest, just remove the reference in the reference node and then execute the following Nugget Command:
Install-Package Azure.Storage.Client

Migration of the membership data


The AspNetProvider was using prefixed SQL tables: aspnet_user, aspnet_membership, etc. The new membership manager is using another sets of tables. We must migrate the data from one set to the other one. Here a SQL script that will to exactly that. The script can be run multiple times because it will only copie the unmoved data.
-- ========================================================
-- Description:    Migrate data from asp_* tables 
--                 to the new table used by Universal provider
-- ========================================================

DECLARE @CNT_NewTable AS INT
DECLARE @CNT_OldTable AS INT

-- --------------------------------------------------------
-- Applications -------------------------------------------

INSERT INTO dbo.Applications (ApplicationName, ApplicationId, Description)
    SELECT    n.ApplicationName, n.ApplicationId, n.Description 
    FROM    dbo.aspnet_Applications o 
    LEFT    JOIN dbo.Applications n ON o.ApplicationId = n.ApplicationId
    WHERE    n.ApplicationId IS NULL

SELECT @CNT_NewTable = Count(1) from dbo.Applications 
SELECT @CNT_OldTable = Count(1) from aspnet_Applications

PRINT 'Application Count: ' + CAST(@CNT_NewTable AS VARCHAR) + ' = ' + CAST(@CNT_OldTable AS VARCHAR)

-- -------------------------------------------------------- 
-- Roles --------------------------------------------------

INSERT INTO dbo.Roles (ApplicationId, RoleId, RoleName, Description)
SELECT    o.ApplicationId, o.RoleId, o.RoleName, o.Description 
FROM    dbo.aspnet_Roles o
LEFT JOIN dbo.Roles n ON o.RoleId = n.RoleId
WHERE n.RoleId IS NULL

SELECT @CNT_NewTable = Count(1) from dbo.Roles 
SELECT @CNT_OldTable = Count(1) from aspnet_Roles

PRINT 'Roles Count : ' + CAST(@CNT_NewTable AS VARCHAR) + ' = ' + CAST(@CNT_OldTable AS VARCHAR)

-- --------------------------------------------------------
-- Users --------------------------------------------------

INSERT INTO dbo.Users (ApplicationId, UserId, UserName, IsAnonymous, LastActivityDate)
SELECT o.ApplicationId, o.UserId, o.UserName, o.IsAnonymous, o.LastActivityDate 
FROM dbo.aspnet_Users o LEFT JOIN dbo.Users n ON o.UserId = n.UserID 
WHERE n.UserID IS NULL

SELECT @CNT_NewTable = Count(1) from dbo.Users 
SELECT @CNT_OldTable = Count(1) from aspnet_Users

PRINT 'Users count: ' + CAST(@CNT_NewTable AS VARCHAR) + ' >= ' + CAST(@CNT_OldTable AS VARCHAR)

-- --------------------------------------------------------
-- Memberships --------------------------------------------

INSERT INTO dbo.Memberships (ApplicationId, UserId, Password, 
PasswordFormat, PasswordSalt, Email, PasswordQuestion, PasswordAnswer, 
IsApproved, IsLockedOut, CreateDate, LastLoginDate, LastPasswordChangedDate, 
LastLockoutDate, FailedPasswordAttemptCount, 
FailedPasswordAttemptWindowStart, FailedPasswordAnswerAttemptCount, 
FailedPasswordAnswerAttemptWindowsStart, Comment) 

SELECT o.ApplicationId, o.UserId, o.Password, 
o.PasswordFormat, o.PasswordSalt, o.Email, o.PasswordQuestion, o.PasswordAnswer, 
o.IsApproved, o.IsLockedOut, o.CreateDate, o.LastLoginDate, o.LastPasswordChangedDate, 
o.LastLockoutDate, o.FailedPasswordAttemptCount, 
o.FailedPasswordAttemptWindowStart, o.FailedPasswordAnswerAttemptCount, 
o.FailedPasswordAnswerAttemptWindowStart, o.Comment 
FROM dbo.aspnet_Membership o
LEFT JOIN Memberships n ON  o.ApplicationId = n.ApplicationId
                      AND o.UserId = n.UserId
WHERE n.UserId IS NULL AND n.ApplicationId IS NULL


SELECT @CNT_NewTable = Count(1) from dbo.Memberships 
SELECT @CNT_OldTable = Count(1) from aspnet_Membership

PRINT 'Memberships count: ' + CAST(@CNT_NewTable AS VARCHAR) + ' >= ' + CAST(@CNT_OldTable AS VARCHAR)

-- -------------------------------------------------------
-- UsersInRoles ------------------------------------------
TRUNCATE TABLE dbo.UsersInRoles
INSERT INTO dbo.UsersInRoles SELECT * FROM dbo.aspnet_UsersInRoles


SELECT @CNT_NewTable = Count(1) from dbo.UsersInRoles 
SELECT @CNT_OldTable = Count(1) from aspnet_UsersInRoles

PRINT 'UsersInRoles count: ' + CAST(@CNT_NewTable AS VARCHAR) + ' >= ' + CAST(@CNT_OldTable AS VARCHAR)


Migration from OSFamilly 1 to 4

Open the file .cscfg and edit the OS Family attribute. It's in the ServiceConfiguration node.
<ServiceConfiguration servicename="MyApp" osFamily="4" osVersion="*" ...>


Wrapping up

The only step left is to deploy in the staging environment to see if everything is working as expected. would recommend also to plan to upgrade as soon as possible because the Azure SDK 2.1 official retirement date is November 2015. I hope this post could help you, even if you are migrating from and to a different version. Any comments, suggestions and/or questions are welcome.
