Using SQL Server Management Studio, I am trying to gauge how many Bytes of data are being processed by SSIS packages. I know how to generate reports in Integration Services Catalogs to view statistics and messages, but these seem to only give statistics on time duration. The following is a sample of the Execution Performance statistics that are provided. Is there a way to view the number of Bytes that were read/written for each package?

At present I don't have direct access to the server logs.

Currently I'm working on system that gathers data from different websites/apis and stores this data in a SQL Server database. Then reporting service generates reports based on this data.
We have a lot of jobs running in SQL Server agent (each job has some steps, each step can be of type - PowerShell script or SQL...).
Version of SQL Server is 2017.
We have a problem that almost every day there are jobs that starts but never ends (status is "Executing"). This job can not run that long.
Does anybody has an idea how to solve this problem? Or at least how to investigate it?
CPU usage on virtual machine is +- 20%. Memory usage - 50%. So it is not a resource problem.
I am using SQL Azure migration wizard for migrating one of my database to a different instance. It literally took more than 12 hours to do BCP out itself. The only change i have doneis to increase the packet size from 4096 to 65535(max). Is that wrong ? And i am doing this from a AWS server which is part of the same subnet where SQL server RDS instance is hosted

Any issues discovered will be reported above.

There is a blog post from the SQL Server Customer Advisory Team (CAT) that goes into a few details about optimal settings to get data into and out of Azure SQL databases.
Best Practices for loading data to SQL Azure
When loading data to SQL Azure, it is advisable to split your data into multiple concurrent streams to achieve the best performance.
Vary the BCP batch size option to determine the best setting for your network and dataset.
Add non clustered indexes after loading data to SQL Azure.
If, while building large indexes, you see a throttling-related error message, retry using the online option.
My current environment is: 3 servers, one for source database, one for destination database and one for IS packages. Now I need to adjust the configurations, like CPU, Memory for each server .
I do believe that running IS packages will consume a lot of resources because of large data volume. However, I do not know which server needs to be configured with more power for IS packages. That is, which server's resource will be mostly used when IS is running?
Also, I need to setup SQL agent for daily ETL processing, then which DB server I should use, the source or destination one?
I'm new to IS deployment,thanks for any advice!
The data will be read from the source server and written to the destination server, so here you need nice fast IO subsystem. Ideally RAID 10. Also, providing your data is split across multiple discs on the source server, more cores will achieve more parallelism. This is not so important on the destination as inserts are normally single threaded.
The server running SSIS needs lots of memory as the data flow buffers will be on this server (providing you run Server Agent here) and you need a fast network connection between all three.
Server Agent should be on the ETL server, otherwise SSIS will consume resources on the box that Server Agent is on, and could therefore fight for threads with SQL Server whilst reading or writing.
I just realized that my application was needlessly making 50+ database calls per user request due to some hidden coding -- hidden in the sense that between LINQ, persistence frameworks and events it just so turned out that a huge number of calls were being made without me being aware.
Is there a recommended way to analyze individual transactions going to my SQL 2008 database, preferably with some integration to my Visual Studio 2010 environment? I want to be able to 'spy' on individual transactions being made, but only for certain pieces of my code, and without making serious changes to either the code or database.
I addition to SQL Server Profiler, there are a number of performance counters you can look at to see both a real time evaluation and a historic trend:
Batch Requests/sec: Effectively measures the number of actual calls made to the SQL Server
Transactions/sec: Number of transactions in each database.
Connection resets/sec: number of new connections started from the connection pool by your site.
There are many more performance counters you can monitor, specially if you want to measure performance, but going through is besides the scope here. A good starting point is Monitoring Resource Usage.
You can use the SQL Profiler tool that comes with SQL Server Management Studio.
Microsoft SQL Server Profiler is a graphical user interface to SQL Trace for monitoring an instance of the Database Engine or Analysis Services. You can capture and save data about each event to a file or table to analyze later. For example, you can monitor a production environment to see which stored procedures are affecting performance by executing too slowly.
As mentioned, SQL Profiler is userful at the SQL Server level. It is not available in SQL Server SSMS Express however.
At the .NET level, LINQ to SQL and the Entity Framework both support logging. See Logging every data change with Entity Framework, http://msdn.microsoft.com/en-us/magazine/gg490349.aspx, http://peterkellner.net/2008/12/04/linq-debug-output-vs2008/.
I am trying to optimize some stored procedures on a SQL Server 2000 database and when I try to use SQL Profiler I get an error message "In order to run a trace against SQL Server you have to be a member of sysadmin fixed server role.". It seems that only members of the sysadmin role can run traces on the server (something that was fixed in SQL Server 2005) and there is no way in hell that I will be granted that server role (company policies)
What I'm doing now is inserting the current time minus the time the procedure started at various stages of the code but I find this very tedious
I was also thinking of replicating the database to a local installation of SQL Server but the stored procedure is using data from many different databases that i will spend a lot of time copying data locally
So I was wondering if there is some other way of profiling SQL code? (Third party tools, different practices, something else )
Your hands are kind of tied without profiler.
You can, however, start with tuning your existing queries using Query Analyzer or
any query tool and examining the execution plans. With QA, you can use
the Show Execution Plan option. From other tools you can use the
SET STATISTICS PROFILE ON / OFF
In query analyser:
SET STATISTICS TIME ON
SET STATISTICS IO ON
Run query and look in the messages tab.
It occurs to me this may require same privileges, but worth a try.
There is a workaround on SQL 2000 to obfuscate the Profiler connection dialogue box to limit the sysadmin connection to running traces only.
