如何从 TFS 获取类似 git 的统计信息

Question

我已经与 TFS 合作几个月了，希望获得一些基本统计数据并将其提供给我们的团队。在 git 中，我可以检索有关“按作者提交”和“按日期提交”等的统计信息。

我想显示来自 TFS（或来自 TeamCity）的类似统计信息。

这可能吗？

Answer 1

我发现研究 TFS 统计数据的最简单方法是使用 Excel 报告 - 您可以根据您能想象到的任何内容进行分析。有关入门指南，请查看我写的这篇博客文章：

TFS 在常规存储库数据之上提供了一个完整的数据仓库供您深入研究。

Answer 2

您可以使用 TFS API 创建任何您喜欢的查询。您可以非常轻松地遍历变更集，查找特定作者的所有提交或在特定日期提交的所有提交：

TfsTeamProjectCollection tpc = new TfsTeamProjectCollection(new Uri("http://tfsserver:8080/"));
tpc.EnsureAuthenticated();
VersionControlServer vcs = tpc.GetService<VersionControlServer>(); 

int latest = vcs.GetLatestChangesetId();
DateTime earliestDate = new DateTime(2011, 1, 1);
do
{
    var changeset = vcs.GetChangeset(latest);                
    if (changeset.CreationDate < earliestDate)
    {
        break;
    }
    // do analysis of the changeset here,
    // e.g. use changeset.Committer or changeset.Changes
} while (latest-- > 0);

在这里您可以找到一些可以在 TFS 数据库上执行的查询来获取一些统计信息。

-- Change this to the name of your collection DB. You’ll need to run these queries for each of your collection DBs. 
USE Tfs_DefaultCollection 
GO

-- Recent Users 
select count(distinct IdentityName) as [Recent Users] from tbl_Command with (nolock)

-- Users with Assigned Work Items 
select count(distinct [System.AssignedTo]) AS [Users with Assigned Work Items] from WorkItemsAreUsed with (nolock)

-- Version Control Users 
select COUNT(*) AS [Version Control Users] from [Tfs_Configuration].[dbo].tbl_security_identity_cache as ic JOIN tbl_Identity as i ON i.TeamFoundationId=ic.tf_id where ic.is_group = 0

-- Total Work Items 
select count(*) AS [Total Work Items] from WorkItemsAreUsed with (nolock)

-- Areas and Iterations 
select count(*) AS [Areas and Iterations] from tbl_nodes with (nolock)

-- Work Item Versions 
select count(*) AS [Work Item Versions] from (select [System.Id] from WorkItemsAreUsed with (nolock) union all select [System.Id] from WorkItemsWereUsed with (nolock)) x 
-- Work Item Attachments 
select count(*) AS [Work Item Attachments] from WorkItemFiles with (nolock) where FldID = 50 
-- Work Item Queries 
select count(*) AS [Work Item Queries] from QueryItems with (nolock)

-- Files 
select count(*) as [Files] from tbl_VersionedItem vi with (nolock) join tbl_Version v with (nolock) on v.ItemId = vi.ItemId where VersionTo = 2147483647

-- Compressed File Sizes 
select (sum(convert(bigint,OffsetTo - OffsetFrom + 1)) / (1024 * 1024)) AS [Compressed File Sizes] from tbl_Content with (nolock)

-- Uncompressed File Sizes 
select (sum(FileLength) / (1024 * 1024)) AS [Uncompressed File Sizes] from tbl_File with (nolock)

-- Checkins 
select max(ChangeSetId) AS [Checkins] from tbl_ChangeSet with (nolock)

-- Shelvesets 
select COUNT(*) AS [Shelvesets] from tbl_Workspace with (nolock) where type='1'

-- Merge History 
select SUM(st.row_count) AS [Merge History] from sys.dm_db_partition_stats st WHERE object_name(object_id) = 'tbl_MergeHistory' AND (index_id < 2)

-- Pending Changes 
select count(*) AS [Pending Changes] from tbl_PendingChange pc with (nolock) join tbl_Workspace w with (nolock) on pc.WorkspaceId = w.WorkspaceId where w.Type = 0 
-- Workspaces 
select COUNT(*) AS [Workspaces] from tbl_Workspace with (nolock) where type='0' 
-- Local Copies 
select SUM(st.row_count) AS [Local Copies] from sys.dm_db_partition_stats st WHERE object_name(object_id) = 'tbl_LocalVersion' AND (index_id < 2)

-- Command Counts 
select Command, count(*) as [Execution Count] from tbl_Command with (nolock) WHERE Command IN ('QueryWorkitems', 'Update', 'GetWorkItem', 'Get', 'VCDownloadHandler', 'Checkin', 'Upload', 'Shelve') GROUP BY Command, Application ORDER BY [Application],[Command]

我发现 Visual Studio Team System Web Access 中的“源”选项卡下有一个更改集视图。选择所需的项目并从项目下拉列表中选择版本历史记录。

这足以满足我的需求。
