Sitecore: Performance debug troubleshooting

There are times when you need to debug your Sitecore codebase and find out what part of the code is taking the most time and troubleshoot page load times. One of the most useful methods is to load the following page (after you have logged into Sitecore)

http://{YourWebsite}/?sc_mode=normal&sc_debug=1&sc_trace=1&sc_prof=1&sc_ri=1&sc_rb=1

sc_mode – don't load the experience editor
sc_debug - turn on the debug mode
sc_trace - turn on Sitecore trace
sc_prof - turn on Sitecore profiler
sc_ri - show rendering information
sc_rb - show rendering borders

Next scroll down to the bottom of your page and you should see something similar to this image


It should show you where the most time is spent. The next step would be to identify the section of your code base that is taking the most time and drill down to more specifics. To find out exactly how long a particular section of code takes, add the following:



You can replace the string "SitecoreingTesting" with anything more relevant to you. Also add multiple of such blocks throughout your code. Next go back to your debug page

http://{YourWebsite}/?sc_mode=normal&sc_debug=1&sc_trace=1&sc_prof=1&sc_ri=1&sc_rb=1

On this page, search for your custom strings like "SitecoreingTesting" and you should see relevant debug and time information that usually is useful to pin point the code that is causing performance issues.

For quick page load time, I found the following chrome extension very useful.

Hope this helps someone during their performance troubleshooting phase. Good luck!

Sitecore: Get list of logged in users

By
I had a deployment today and wanted to find a list of users who were logged into the Sitecore admin site. This was mainly so that I can contact them and let them know that a deployment was going to happen. I found the following link very useful as it gave me exactly what I was looking for. A list of users that were logged in and I contacted them. It also has the ability to Kick off users! http://{YourWebsite}/sitecore/client/Applications/LicenseOptions/KickUser Note: You can only see other users in this list if you have the right administrator permission. Logging in with a lower access level user only gave me the logged in user and no one else on the list.

Create Object XML while Debugging in VS

By
 There are times when you put breakpoints in Visual studio and read object values within Visual Studio. This is all good if you are doing some debugging. But if you want to save an object like a Json object in Visual studio there isn't a straightforward way to do that. I found this piece of code that I copied and pasted in the Immediate Window in Visual Studio and was able to save the object as an XML file. (new System.Xml.Serialization.XmlSerializer(YourObject.GetType())).Serialize(new System.IO.StreamWriter(@"c:\tmp\YourObject.xml"), YourObject) Happy Sitecoreing!

Updating Sitecore Image alt text

By
One of the most important conditions of making a site accessible is to make sure that all images on the site have the alt field with some value that describes the image. The simplest update we can make to Sitecore is to have the alt field automatically get the image file name. That way even if content authors forget to fill the alt field, it is pre-filled with the file name. To do this just add $name to the alt field in the standard value of an image [/sitecore/templates/System/Media/Unversioned/Image/__Standard Values] This is all good for an future images that gets uploaded to Sitecore. But what about all the existing images. For that we can write a PowerShell script (see below) to get all images in the Sitecore image folder that have empty alt tags. Export that to a csv file. $pathOfImages = "master:/sitecore/media library/MyImages" $images = Get-ChildItem -Path $pathOfImages -Language * -Recurse | Where-Object { ($_.Fields["Alt"] -ne $null) -and ($_.Fields...
