TFS storage use part 2

In the previous article we looked at the TFS storage growth over time.
Now it is time to dive into this and look at what is actually consuming the space.

The first query to run on the collection is a standard SQL query that tells us the top 10 storage consuming tables. (This can be used on any SQL database)

SELECT TOP 10 o.name,
SUM(reserved_page_count) * 8.0 / 1024 SizeInMB,
SUM(CASE
WHEN p.index_id <= 1 THEN p.row_count
ELSE 0
END) Row_Count
FROM sys.dm_db_partition_stats p
JOIN sys.objects o
ON p.object_id = o.object_id
GROUP BY o.name
ORDER BY SUM(reserved_page_count) DESC

To get even further details about the TFS storage use, we can look at the different TFS areas:

SELECT Owner =
CASE
WHEN OwnerId = 0 THEN 'Generic'
WHEN OwnerId = 1 THEN 'VersionControl'
WHEN OwnerId = 2 THEN 'WorkItemTracking'
WHEN OwnerId = 3 THEN 'TeamBuild'
WHEN OwnerId = 4 THEN 'TeamTest'
WHEN OwnerId = 5 THEN 'Servicing'
WHEN OwnerId = 6 THEN 'UnitTest'
WHEN OwnerId = 7 THEN 'WebAccess'
WHEN OwnerId = 8 THEN 'ProcessTemplate'
WHEN OwnerId = 9 THEN 'StrongBox'
WHEN OwnerId = 10 THEN 'FileContainer'
WHEN OwnerId = 11 THEN 'CodeSense'
WHEN OwnerId = 12 THEN 'Profile'
WHEN OwnerId = 13 THEN 'Aad'
WHEN OwnerId = 14 THEN 'Gallery'
WHEN OwnerId = 15 THEN 'BlobStore'
WHEN OwnerId = 255 THEN 'PendingDeletion'
END,
SUM(CompressedLength) / 1024 / 1024 AS BlobSizeInMB
FROM tbl_FileReference AS r with (nolock)
JOIN tbl_FileMetadata AS m
ON r.ResourceId = m.ResourceId
AND r.PartitionId = m.PartitionId
WHERE r.PartitionId = 1
GROUP BY OwnerId
ORDER BY 2 DESC

Disclaimer: These scripts are heavily inspired by various scripts found around the internet over time.

Next time we look at how the build system uses the storage.
