I have created a PowerBI. The source of the data is a SQL database. The amount of data I am working with is over 4M rows but unfortunately, PowerBI is not able to load the data. When I look at the TaskManager (see image), I see multiple subprocesses that seem to be running in the background. The file does not give me an error, but it just runs the entire night and still does not load the 4-5M rows.
Is this something y'all have seen before? None of my colleagues have seen this. Would love any inputs.
Thank you,

Two years ago a SQL expert opened a SSMS and showed all queries as they were happening in real time. That way he saw which SQL statements were running fast and which took some time to be ran. I remember the queries to be displayed in a "CMD" look alike window. I can't remember if new queries were displayed at the top or were they shown at the bottom of the window.
For the past month I have been trying to figure out how he got this working. I looked everywhere in monitor, but I can't find anything similar to what he showed me than.
The results were similar to the "claymore eth miner window" ...
Can someone point me in the direction of getting this?
You can use sp_whoisactive to get the current running queries. It is very useful to see if currently there is blocking, locking, long running statements.
In order to get better picture of what was going on in the past, you can enable the Query Store. There are some predefined reports:
and various statistics and it is user friendly:
We have a process that generates around 20,000 PDFs using SSRS as the backend.
The mechanism used to generate these is the Report Execution 2005 API endpoint
We have just performed a run where occasionally a PDF would be generated missing some data, or the header or the body or the footer.
The break down of that was around 12,000 generated correctly, 1000 blank, 7000 data incorrect.
There doesn't seem to be a rhyme or reason for this, no pattern in the data or timings. In the logs we can see the following:
We log all parameters used to execute these reports in a DB, so using this we went and re-run that report with the same parameters and it ran fine. We then went and took 100 of the random errored ones, ran them manually and they all worked fine.
My only straw left to grasp at is there is some caching or SSRS deep issue that is causing this.
If anyone has seen something similar or has an opinion on where to check next, would be much appreciated.
I've a task wherein I'm required to work with Microsoft Word document and database. Basically the word document has numerous charts that are created by users in two steps, first is to prepare charts in excel, then take screenshot and paste in Word document. It's tedious process as it requires re-doing charts anytime someone wants to do what-if simulations.
When I insert a chart in Word, the underlying data comes from Excel Sheet which I am able to fetch from database as 1 time operation, but it's not productive that much as users will have to open excel sheet, refresh data in sheet manually.
I tried to find different solutions but I'm blank as it's totally new work for me, there are elementary examples suggesting VSTO but I couldn't find more detailed examples specifically for charts like the scenario I've.
Has anyone tackled similar issue? If so please advise. I'm open to use either VSTO, OpenXML or even R packages that can help to auto-generate word document with updated charts.
Thank you.
I found solution by using R, it satisfies what I was looking for. A related task and steps are in my other question are here!
Since Android is open source, I guess there won't be problem if I use the data for my project. I want to do a project where I need a dataset that contains bug reports that many users have sent across the world, and I want to predict the severity of the bug by analyzing the report either by performing text mining on the description of the report or by stacktracing. But, the main problem is Dataset. Can someone tell me how do I get the dataset for this project? Also, if you have any idea on this project, help me out.
I have recently started working with jMeter. And I was doing database stress testing for that. I have added the required drivers in the lib folder. And my jMeter is connected to database. And it works fine.
But the problem now I am facing is how to interpret those results. I just tested only one SQL which is doing SELECT on one table. Below is the screenshot of my various tabs in JMeter.
This below screenshot shows how many threads (10) I am running and Ramp up time.
This below screenshot shows me JDBC Connection Configuration settings, which I am not able to understand as well. It will be great if anyone can throw some thoughts on this what does it mean corresponding to number of threads I am running in my above picture.
This Below screenshot shows the result in a Summary report which I am again not able to interpret. What's the best way to interpret these results? Any thoughts on this will be of great help.
This Below screenshot shows the result which I am again not able to interpret. What's the best way to interpret these results? I was looking for how much time it is taking to execute that one single Select SQL. And this tab shows me lot of information but not sure how to interpret those. Any thoughts on this will be of great help.
Can anyone help me understanding these results? Thanks for the help.
You should use one of these:
Response Time Graph
Aggregate Graph
Look also at jmeter-plugins project:
