Get Statistics

To get collection statistics, use GetCollectionStatisticsOperation:

// Pass an instance of class `GetCollectionStatisticsOperation` to the store 
CollectionStatistics stats =
    store.Maintenance.Send(new GetCollectionStatisticsOperation());

Statistics are returned in the CollectionStatistics object.

// Collection stats results:
public class CollectionStatistics
{
    // Total # of documents in all collections
    public int CountOfDocuments { get; set; }
    // Total # of conflicts
    public int CountOfConflicts { get; set; }
    // Total # of documents per collection
    public Dictionary<string, long> Collections { get; set; }
}

To get detailed collection statistics, use GetDetailedCollectionStatisticsOperation:

// Pass an instance of class `GetDetailedCollectionStatisticsOperation` to the store 
DetailedCollectionStatistics stats =
    store.Maintenance.Send(new GetDetailedCollectionStatisticsOperation());

Statistics are returned in the DetailedCollectionStatistics object.

// Detailed collection stats results:
public class DetailedCollectionStatistics
{
    // Total # of documents in all collections
    public long CountOfDocuments { get; set; }
    // Total # of conflicts
    public long CountOfConflicts { get; set; }
    // Collection details per collection
    public Dictionary<string, CollectionDetails> Collections { get; set; }
}

// Details per collection
public class CollectionDetails
{        
    public string Name { get; set; }
    public long CountOfDocuments { get; set; }
    public Size Size { get; set; }
    public Size DocumentsSize { get; set; }
    public Size TombstonesSize { get; set; }
    public Size RevisionsSize { get; set; }
}

To get database statistics, use GetStatisticsOperation:

// Pass an instance of class `GetStatisticsOperation` to the store 
DatabaseStatistics stats =
    store.Maintenance.Send(new GetStatisticsOperation());

Statistics are returned in the DatabaseStatistics object.

// Database stats results:
public class DatabaseStatistics
{
    public long? LastDocEtag { get; set; }      // Last document etag in database
    public long? LastDatabaseEtag { get; set; } // Last database etag
    
    public int CountOfIndexes { get; set; }     // Total # of indexes in database
    public long CountOfDocuments { get; set; }  // Total # of documents in database
    public long CountOfRevisionDocuments { get; set; }  // Total # of revision documents in database
    public long CountOfDocumentsConflicts { get; set; } // Total # of documents conflicts in database
    public long CountOfTombstones { get; set; }         // Total # of tombstones in database
    public long CountOfConflicts { get; set; }          // Total # of conflicts in database
    public long CountOfAttachments { get; set; }        // Total # of attachments in database
    public long CountOfUniqueAttachments { get; set; }  // Total # of unique attachments in database
    public long CountOfCounterEntries { get; set; }     // Total # of counter-group entries in database
    public long CountOfTimeSeriesSegments { get; set; } // Total # of time-series segments in database
    
    // List of stale index names in database
    public string[] StaleIndexes => Indexes?.Where(x => x.IsStale).Select(x => x.Name).ToArray();
    // Statistics for each index in database
    public IndexInformation[] Indexes { get; set; }
    
    public string DatabaseChangeVector { get; set; } // Global change vector of the database
    public string DatabaseId { get; set; }           // Database identifier
    public bool Is64Bit { get; set; }                // Indicates if process is 64-bit
    public string Pager { get; set; }                // Component handling the memory-mapped files
    public DateTime? LastIndexingTime { get; set; }  // Last time of indexing an item
    public Size SizeOnDisk { get; set; }             // Database size on disk
    public Size TempBuffersSizeOnDisk { get; set; }  // Temp buffers size on disk
    public int NumberOfTransactionMergerQueueOperations { get; set; }
}

To get detailed database statistics, use GetDetailedStatisticsOperation:

// Pass an instance of class `GetDetailedStatisticsOperation` to the store 
DetailedDatabaseStatistics stats =
    store.Maintenance.Send(new GetDetailedStatisticsOperation());

Statistics are returned in the DetailedDatabaseStatistics object.

// Detailed database stats results:
public class DetailedDatabaseStatistics : DatabaseStatistics
{
    // Total # of identities in database
    public long CountOfIdentities { get; set; }
    // Total # of compare-exchange items in database
    public long CountOfCompareExchange { get; set; }
    // Total # of cmpXchg tombstones in database
    public long CountOfCompareExchangeTombstones { get; set; }
    // Total # of TS deleted ranges values in database
    public long CountOfTimeSeriesDeletedRanges { get; set; }
}

• By default, you get statistics for the database defined in your Document Store.
• Use ForDatabase to get database and collection statistics for another database.
• ForDatabase can be used with any of the above statistics options.

// Get stats for 'AnotherDatabase':
DatabaseStatistics stats =
    store.Maintenance.ForDatabase("AnotherDatabase").Send(new GetStatisticsOperation());
