Developer Dashboard in SharePoint  2013


Developer dashboard is very help full while troubleshooting the issues related to performance in SharePoint 2013. 

How to enable it ?

To enable dashboard you need to create the Usage and Health Data Collection Service Application.

Use the below powershell command to create the service application.

New-SPUsageApplication -Name "Health and Usage Application" -DatabaseName "SP2013_Health_and_Logging_Database".


UsageApplication

Once you run the above command it will create the service application with the name Health and Usage Application and the respective database.

Once you have created the service application you have to enable the dashboard.

In the previous versions we use to get three options ON/OFF/OnDemand settings for the dashboard.

Now in this version you will get only two options ON/OFF.

To enable the dashboard, we will use ON setting and use the below powershell command.

$svc = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$dds = $svc.DeveloperDashboardSettings
$dds.DisplayLevel = "On"
$dds.Update()

After executing the above powershell command open your site on top right hand side of your site, you can see an icon to launch Developer Dashboard. Please see below Figure:1

You can enable the dashboard setting with object model as well.

Once you click on "Launch the developer dashboard" it will open the below Figure : 2

In that figure you can see what are requests, against each request you can observe server info, in server info  Aggregate status will give how many SQL queries have run, how many SharePoint requests and services has been called  what is duration for each of them etc.

SQL queries running against each request:

One of the most important criteria while designing the SharePoint solution is SQL. Because the performance of SharePoint depends on the SQL. We need for what type of queries runs in the background for each request so that it will be a great help for while troubleshooting the performance issues related to SharePoint.

Once you go to the SQL section of the dashboard you can see the queries name and execution plan details will get displayed once you click on those links.

Other than that there are few important parameters which will help us while troubleshooting the performance issue like what is the total duration to performance query, how many reads and write operations done by the query to the SQL server.

This makes easier for SQL DBA to troubleshoot the issues related to performance of SharePoint.

Please see the below Figure where it displays the portion of a query execution plan.

ULS logs:

There are many cases where you want to check the error messages related to only that particular request.

In this dashboard we have a separate section for the ULS logs to check against each and every request.

MDS (Minimal download strategy):

One of the new feature in SharePoint 2013 is a minimal download strategy.

Earlier days whenever you access the page the complete page reloads again, it causes the decrease in performance. In SharePoint 2013 it's not the case, it will load only portion of the page if there is any change so it drastically improves the performance of the application.
