Usually, when "Most popular" content feature needs to be implemented, developers choose to add a connection string to the reporting database to the CD instances and run a SQL statement that produces necessary output. However, it is not always possible to do that due to security reasons. We ran into a situation when calling Reporting database directly was not allowed, therefore we chose a different approach. Below you'll find an overview of the solution.
AnalyticsHelper:
TrackingService:
This code allows us to record the Page Event and LongId as its CustomValue where we store the IDs of all ancestors.
https://github.com/jcore/Sitecore.PopularItems/blob/master/ItemPath.sql
ItemPathProcessor is responsible for the processing of an interaction and storing the ItemPath data in the new SQL tables if there is an Item Path specified.
https://github.com/jcore/Sitecore.PopularItems/blob/master/ItemPathProcessor.cs
Below you can see the patch file that enables the ItemPathProcessor:
As you can see Dimension classes match the [ItemPath] SQL table columns and the Fact classes match the [Fact_PageItemPaths] one.
The first portion of the most popular feature is implemented - the data is collected.
Requirements:
- Display two of the most popular items that are based on a list of allowed templates
- The most popular items should live under the same section as the context item.
Gathering the information about a page view and the section
To collect the data about user visit and the section the item belongs to we implemented the following helper and placed it in DefaultLayout.cshtml that is being used by every single page item on the site.
@Html.Custom().PageViewWithSectionTracking(Sitecore.Context.Item.ID, Sitecore.Context.Item.TemplateID, SwitchingLinkManager.GetItemAncestors(Sitecore.Context.Item))
We have a custom LinkProvider implemented in the solution for items that live in buckets and are stored outside of the normal site tree structure. Therefore we have a helper method that retrieves all ancestors for an item and passes that to the helper method. The ancestors are not necessarily the ancestors of an item in the tree, but logical ancestors.
The PageViewWithSectionTracking method looks like this:
public static HtmlString PageViewWithSectionTracking(this CustomHelper helper, ID itemId, ID templateId, IEnumerable- ancestors) { return new HtmlString(AnalyticsHelper.TrackPageViewWithSectionPath(itemId, templateId, ancestors)); }
AnalyticsHelper:
public static class AnalyticsHelper
{
private static readonly ITrackerService TrackingService = (ITrackerService)ServiceLocator.ServiceProvider.GetService(typeof(ITrackerService));
public static string TrackPageViewWithSectionPath(ID itemId, ID templateId, IEnumerable- ancestors)
{
try
{
if (TrackingService != null)
{
var id = new ID(Constants.PageViewEventId);
TrackingService.TrackCurrentPageWithSectionEvent(id, itemId, templateId,ancestors);
}
}
catch (Exception ex)
{
Log.Error(ex.Message, ex, typeof(AnalyticsHelper));
}
return string.Empty;
}
}
TrackingService:
public virtual void TrackCurrentPageWithSectionEvent(ID pageEventId, ID itemId, ID templateId, IEnumerable- ancestors) { Assert.ArgumentNotNull(pageEventId, nameof(pageEventId)); if (!IsActive) { return; } var pageEventDefinition = Tracker.MarketingDefinitions.PageEvents[pageEventId]; Assert.IsNotNull(pageEventDefinition, $"Cannot find page event: {pageEventId}"); var pageData = new PageEventData(pageEventDefinition.Alias, pageEventDefinition.Id); var longId = ancestors != null ? string.Join("/", ancestors.Select(i=> i.ID)) : string.Empty; pageData.CustomValues.Add("LongId", longId); pageData.CustomValues.Add("TemplateId", templateId.ToGuid().ToString()); pageData.ItemId = itemId.ToGuid(); Tracker.Current.CurrentPage.Register(pageData); }
This code allows us to record the Page Event and LongId as its CustomValue where we store the IDs of all ancestors.
Processing collected data
Once the data is collected in the collection database, we need to make sure it is processed correctly and aggregated into custom tables that live in the Reporting database. For that, we need to implement the Dimension and Fact Key and Value classes, the processor to process the interactions and the following SQL tables:https://github.com/jcore/Sitecore.PopularItems/blob/master/ItemPath.sql
ItemPathProcessor is responsible for the processing of an interaction and storing the ItemPath data in the new SQL tables if there is an Item Path specified.
https://github.com/jcore/Sitecore.PopularItems/blob/master/ItemPathProcessor.cs
Below you can see the patch file that enables the ItemPathProcessor:

Dimension Key class
public class ItemPathDimensionKey : DictionaryKey
{
public Guid ItemId { get; }
public ItemPathDimensionKey(Guid itemId)
{
ItemId = itemId;
}
}
Dimension Value class
public class ItemPathDimensionValue : DictionaryValue
{
[CanBeNull]
public string ItemPath { get; }
[CanBeNull]
public string TemplateId { get; }
public ItemPathDimensionValue([CanBeNull] string itemPath, [CanBeNull] string templateId)
{
ItemPath = itemPath;
TemplateId = templateId;
}
}
Fact Key class
public class ItemPathFactKey : DictionaryKey
{
public DateTime Date { get; set; }
public Guid ItemId { get; }
public ItemPathFactKey(Guid itemId)
{
ItemId = itemId;
}
}
Fact Value class
public class ItemPathValue : DictionaryValue
{
public long Visits { get; set; }
public long Value { get; set; }
[NotNull]
internal static ItemPathValue Reduce([NotNull] ItemPathValue left, [NotNull] ItemPathValue right)
{
Debug.ArgumentNotNull(left, "left");
Debug.ArgumentNotNull(right, "right");
ItemPathValue result = new ItemPathValue
{
Visits = left.Visits + right.Visits,
Value = left.Value + right.Value
};
return result;
}
}
As you can see Dimension classes match the [ItemPath] SQL table columns and the Fact classes match the [Fact_PageItemPaths] one.
The first portion of the most popular feature is implemented - the data is collected.
Displaying the most popular items within a given section
If your security configuration permits to call the Reporting database directly you can do so. Make sure you put caching on every resultset you get to avoid putting a lot of traffic on the Reporting database. It is not designed to sustain large traffic.
To avoid connecting to the Reporting database directly we chose to implement a custom Solr index that would store the data from the reporting database. Sitecore CM would update the index on a schedule.
Here is the config patch file for the new index.

Most Popular item Service
After all the data is collected and the index is built, we can start querying the index retrieving the values for most popular articles. Below is the code for the method that returns the IEnumerable of item IDs.
public IEnumerableGetMostPopularItemsForSection(IEnumerable templateIds, ID parentId, int count) { try { var cacheKey = $"{count}-{parentId}-{string.Join("-", templateIds)}"; var cachedItemIds = (IEnumerable )PageViewCache.CacheWrapper.Get(cacheKey); if (cachedItemIds == null) { var indexName = Settings.GetSetting("Reporting.IndexName", "sitecore_reporting_index"); using (var context = ContentSearchManager.GetIndex(indexName).CreateSearchContext()) { var results = context.GetQueryable ().Where(i => i.ItemPath.Contains(parentId) && templateIds.Contains(i.TemplateId) && i.Datasource == "reporting_pageviewswithpath").OrderByDescending(i=>i.Visits).Take(count).ToList(); if (results != null && results.Count > 0) { cachedItemIds = results.Select(i => i.ItemId); PageViewCache.CacheWrapper.Set(cacheKey, cachedItemIds); return cachedItemIds; } } } return cachedItemIds; } catch (Exception ex) { LogManager.Error(ex.Message, ex, this); } return null; }
Conclusion
This solution offers a food for thought when it comes to displaying content from the reporting database. We have solved the issue of connecting to Reporting database from CDs that very often live in completely different network group that CM. Also often querying Solr index is faster than querying SQL.
