Here I have mentioned the code which can be useful to get the Content DB, Site Collection Usage details.
SPFarm farm = SPFarm.Local;
SPWebService service = farm.Services.GetValue<SPWebService>("");
string webappName = "";
SPWeb web = null;
SPUserCollection owners = null;
string OwnerString = "";
int count = 0;
foreach (SPWebApplication webapp in service.WebApplications)
{
webappName = webapp.Name.ToString();
SPContentDatabaseCollection DBCollection = webapp.ContentDatabases;
foreach (SPContentDatabase contentDB in DBCollection)
{
//ContentDB details
row = null;
row = tableDB.NewRow();
row[col1] = webappName;
row[col2] = contentDB.Name.ToString();
//Get the ContentDB size from farm database server
SqlConnection con = new SqlConnection(contentDB.DatabaseConnectionString.ToString());
SqlCommand com = new SqlCommand("select Sum(size/128) from sys.database_files", con);
try
{
con.Open();
row[col3] = Convert.ToInt64(com.ExecuteScalar());
con.Close();
}
catch (Exception ex)
{
WritetoEventViewer("Exception(ContentDB size calculation from farm DB) : " + ex.Message.ToString());
}
finally
{
con.Dispose();
}
row[col4] = Convert.ToInt64(contentDB.CurrentSiteCount);
row[col5] = Environment.MachineName;
tableDB.Rows.Add(row);
//Site collection details
foreach (SPSite site in contentDB.Sites)
{
try
{
rowSite = null;
rowSite = tableSite.NewRow();
rowSite[Server] = Environment.MachineName;
rowSite[WebApp] = webappName;
rowSite[ContentDBName] = contentDB.Name.ToString();
rowSite[URL] = site.Url.ToString();
rowSite[Size] = site.Usage.Storage; // in bytes
rowSite[Quota] = site.Quota.StorageMaximumLevel; // in bytes
//Get the Users from site collection's owner group
OwnerString = "";
web = site.RootWeb;
if (web.AssociatedOwnerGroup != null)
owners = web.AssociatedOwnerGroup.Users;
if ((owners != null) && (owners.Count > 0))
{
count = 0;
foreach (SPUser user in owners)
{
string loginname = user.LoginName.ToString();
//To remove extra characters from claims
if(loginname.IndexOf("i:0#.w|") >= 0)
loginname = loginname.Replace("i:0#.w|", "");
if (count == 0)
{
OwnerString = loginname;
count++;
}
else
{
count++;
OwnerString = OwnerString + "; " + loginname;
}
}
}
rowSite[Owner] = OwnerString;
rowSite[ReadLocked] = site.ReadLocked;
rowSite[ReadOnly] = site.ReadOnly;
rowSite[CurrentResourceUsage] = site.CurrentResourceUsage;
rowSite[WriteLocked] = site.WriteLocked;
rowSite[UsageBandwidth] = site.Usage.Bandwidth;
rowSite[UsageHits] = site.Usage.Hits;
rowSite[UsageVisits] = site.Usage.Visits;
tableSite.Rows.Add(rowSite);
}
catch (Exception ex)
{
WritetoEventViewer("Exception(Site Collection details collection) : " + ex.Message.ToString());
}
finally
{
owners = null;
if (web != null)
web.Dispose();
if (site != null)
site.Dispose();
}
}
}
}
