How to get usage information for a specific site collection by code

To get usage information for a site collection, have a look at the Usage property of the SPSite class.

This property is a structure which contains 5 fields:
- Storage: total amount of storage (bytes) consumed
- DiscussionStorage: amount of storage (bytes) used by the web discussion data
- Hits: cumalative number of visits
- Bandwidth: cumulative bandwith used
- Visits: cumulative number of visits

Note that 2 (Storage and DiscussionStorage) are updated in real time and 3 (Bandwidth, Hits and Visits) are updated daily by the usage analysis timer job.

The following console application displays the usage information for a specific site collection:

using System;

using System.Collections.Generic;

using System.Text;

using Microsoft.SharePoint;

namespace UsageInformation

{

    class Program

    {

        static void Main(string[] args)

        {

            using (SPSite siteCollection = new SPSite("http://siteCollectionUrl"))

            {

                Console.WriteLine(string.Format("SiteCollection Url: {0}", siteCollection.Url));

                Console.WriteLine(string.Format("Storage: {0}", siteCollection.Usage.Storage));

                Console.WriteLine(string.Format("Discussion Storage: {0}", siteCollection.Usage.DiscussionStorage));

                Console.WriteLine(string.Format("Bandwidth: {0}", siteCollection.Usage.Bandwidth));

                Console.WriteLine(string.Format("Hits: {0}", siteCollection.Usage.Hits));

                Console.WriteLine(string.Format("Visits: {0}", siteCollection.Usage.Visits));

                Console.WriteLine(string.Format("Press a touch to exit..."));

                Console.ReadLine();

            }

        }

    }

}
