How to enable time metrics per line in VS 2015

VS2013

Just installed VS 2015 and I am not seeing how to enable the ms processing time per line. I saw the ability when at MS Build this year but apparently it is not doing it by default. I have looked through the options settings but nothing is standing out as to how to enable it.

Has anyone done this yet?

What time? Time of what processing?
Do you understand that code is not really compiled line by line, and not executed line by line. So, what is it?

In case you are unaware there is processing metrics offered in the VS 2015 IDE. It has nothing to do with compile, but run time processing. The metrics allow the developer to troubleshoot long running methods and memory leaks.

Sergey Alexandrovich Kryukov 21-Jul-15 13:37pm

Usually, this is called "profiler". No, I did not know that, as I want to wait for the final release. Thank you for telling me that. This is another reason why you should have explained it properly. You did not mention anything like runtime or compile time. And I still don't know what is "processing per line". I'm sure it makes certain sense, but everything should be properly defined.

Well it was clear to the other commented posted so it can not be that vague. Yes they are called profilers but that is more vague even as it could indicate memory etc.

I wanted to know specifically the processing time of the line in ms (mili seconds).
FYI, VS 2015 was officially released yesterday.

As far as I know, you have nothing to do except probably use the new debug engine which would be selected by default. Also, I think that it is only written if elapsed time is above a small threshold.

[no name] 21-Jul-15 13:19pm

You are correct. It does show up by default but was simply not where I expected it. It is however always written but will simply say <1ms if so small.

Sergey Alexandrovich Kryukov 21-Jul-15 13:20pm

The question is why? I guess, to make this "processing" even slower. :-)

It reminds me the old joke: "An autopsy revealed that the patient died as a result of the autopsy." :-)
I hope you can see the point.

I have troubleshot many applications, and monitoring the process does slow it but it also tells you your bottlenecks so you are able to improve them. Obviously you do not run in debug mode when you deploy the system , unless of course you used a metric analyzer that is integrated into your code base. I would not recommend that (but have seen that). Instead, you can now just use VS 2015 out of the box and run in debug mode. Quite simples.

Sergey Alexandrovich Kryukov 21-Jul-15 13:40pm

After your explanation, I have better understanding on what is it, but still incomplete. Thank you for telling me that. No, it's not really simple; here is why: any runtime time measurements need extra time, don't they? :-)

Oh absolutely!
There are so many complexities to getting such metrics and thus has been such an issue for development for so long. I am so happy they have integrated such tooling right into my favorite IDE!
Here is an interesting post on it.

(my flash is giving an error in the link)

It is great that now such profiling will not be done necessarily at the end of development because with the tooling integrated as you develop we will (hopefully) observe the issues as we code them and immediately correct them.

Philippe Mori 21-Jul-15 13:53pm

Impact on performance would be negligeable as it would take more time to update variables and stack Windows than timing the time between the beginning and the end of a step.
It does replace full blown profiling but displaying elapsed time after each step can help to detect some performance problem.

Sergey Alexandrovich Kryukov 21-Jul-15 14:04pm

It really depends on what you do. If you do extremely fast iterations, but great number of them, timing a point inside the loop will never be negligible. I hope you understand it. Perhaps the profiler can subtract the time taking for its own operation, but this would be quite far from trivial.

THats what you work from top up :)
You would be profiling the method running the loop and see the method took ##ms and realize you are not happy with that. Then you would look into the method and address as necessary. Does the loop have too many iterations? Can it be done async? All kinds of potential. The metrics do nothing other than guide you where to look, but you still have to use your brain :)

Sergey Alexandrovich Kryukov 21-Jul-15 14:18pm

I do understand the value and practical use of profilers. I'm talking on the fundamental issue now: the effect of measuring tool on the object of measurements. Generally, this is an unavoidable problem.
Good point about the proper use of the brain! :-)
—SA

Philippe Mori 21-Jul-15 14:55pm

This profiler is not intented for fast-iterations (less than 1ms) but to helper detect slow code (maybe a poor SQL query, slow connection). It is still better than stepping code and use our own feeling on how long the debugger take before returning. Sometime a rough idea is just enough...

Wow people are raging @$$h01es. Why is this a 1?

Justify your asinine vote. The question was completely valid and written fine. If you do not understand it that does not mean it is poorly written. It means move on as this does not concern you. This community is going down the #$&^er.

Matthew Dennis 21-Jul-15 13:45pm

Actually, the question lacks the context of seeing the time metrics during debugging.
VS has a lot of features that change depending on what you are doing.
I suggest that you edit your question to make it clearer where you expected the metrics so that others can understand you problem and benefit from the answers.

[no name] 21-Jul-15 13:48pm

The question is "How to enable time metrics per line in VS 2015"
How much more context do you need to see time metrics during debugging than that?
Jesus flip people, maybe read the actual question before responding.

Cussing at a site admin generally does not end well for the non-admin...

[no name] 21-Jul-15 13:52pm

Admins critisizing users for the questions without actually reading the question does not end well for the site...

[no name] 21-Jul-15 14:26pm

Okay. Sorry, did not realize you had that kind of power.

[no name] 21-Jul-15 14:32pm

Didn't say I had any power. But I can draw lines and connect dots and as I implied admins critisizing users about their questions with out actually reading the question does not indicate a well run site.... A site that is not run well... Well I think you get the drift and are also able to connect dots.

But I do have super powers. They just do not apply here.

[no name] 21-Jul-15 13:47pm

Because some of (high-rep) mems do think they are god. It is really a shame for them to be that pedantic! It comes to a point that nobody will ask a question here because one has to be afraid to be downvoted.

The same is if a low rep mem like me answers a question, the chance is very high that I get downvoted.

This is not my understanding of sharing knowledge. It is more and more hunting for points and "supremacy"

Sad, sad, sad......

Wish I could give you some up-votes for your comment ;)

Consider it done :)

Sergey Alexandrovich Kryukov 21-Jul-15 14:14pm

I recently up-voted your question a bit, but only because you answered some of my questions in comments, thank you.

I would never do that in response to your really abusive comment with that "@$$..." expression. Please understand that you should never behave like that, otherwise it can lead to abuse reports and cancellation of your account. Absolutely everything is discussed, but personal characteristics, especially in such terms, should not be tolerated (did you know that in some cultures dirty expressions or even hints to them are considered almost deadly sins? in others they are normal; it's better to be on safe side). I did not want to discuss anything with you, but your answers improved the picture. Will you better edit out that expression, to end up this unpleasant topic? Nothing personal, okay?

Fair points, but to what end can we correct the absurd behavior that I am reporting?
Why in the world would a simple QA receive multiple 1 votes with out any explanation? I call it like I see it. If the admins want to ban such behavior then I want no part of the site anyways.
QA is meant to be quick QA not deep discussions as we have a forum for that. The question was simply stated and may not have been the clearest to you or all, but as I said the second response got it so I doubt the clarity was actually that bad. Moreover, it certainly was not bad enough for members to vote it as a 1. It is a scale of 1 to 5 for a reason.
Finally, if a person votes they should state why and simply not understanding is not a reason. As stated just because you do not understand something does not mean it was a poor question. It means you do not understand it and maybe should leave it alone.

But I do thank you for your time and responses.

PS "Finally" other cultures are really not my concern. If a person takes offense to characters and words they probably should get off the webs. I am not in the business of caring about what offends people really especially in a world where you can just click one button and get away from the said "deadly sin". Now, if we worked directly with each other etc. it would be different. But seriously this is a QA. Taking offense to a comment is a bit silly and even more silly to take some action on it.

But hey, as I said earlier if admins want to keep such silly QA behavior (asinine voting) and punish those that call it like it is so be it. If I wanted to participate in a technical rep circle jerk I would spend more time at SO. I use to find this site quite quick and resourceful.... use to.

Sergey Alexandrovich Kryukov 21-Jul-15 16:06pm

Please understand, by the rules, no one is obliged to claim or motivates the down-votes. I receive plenty of down-votes myself, and the pattern I can see is: it's on worst and best posts. Some conducted real hatred attacks. I commented on this question a lot more that it's usually done.

But I hardly can agree with you on cultures and bad words, especially on "other cultures are really not my concern"; I consider such position as unethical. The idea to "get off the Webs"? Perhaps, your misconception is that I take things like that as personal offense. Not even close, it would be just impossible. I just try to protect common environment from contamination I find unacceptable.

Thank you.

Lack of rules is hardly an excuse to justify such behavior especially from community regulars.

How is it unethical to disregard others cultures? I should bend over to adhere to other peoples feelings in a thread that I started? That makes no sense except for those living in non-secular states that demand everyone recognize their asinine way of life which by definition I then have no respect for because it goes against "MY" culture.

I did not mean to imply you specifically were taking offence. You were pointing out others might, to which I really don't care. To view that as "unethical" is silly. Are we to protect everyones feelings?
What if someone posts an article about some tech being "dead" and worthless but a member has dedicated their life to said technology. Surely they will take some offense to it, but who cares?
As stated if something offends a person on the internet they should simply ignore it. Almost all other actions seem illogical as it merely draws attention to what they found offensive in the first place thus offending them even more.

Sergey Alexandrovich Kryukov 21-Jul-15 16:30pm

I understand. Well, we may have used different meaning by "disregards". I'm really sorry that you think my view is silly, but it's up to you. Aren't you protecting your own feeling and don't want to protect others?
Anyway, don't you think we spend too much time over non-scientific and non-technical issues? I think this is wrong. Can we quite on that, please?
Thank you.

Of course I protect my view as I would expect anybody to do! But no I do not feel I need to protect other's views especially when it does not fall in line with mine at all. That is not to say, I do not expect them to have their view or expect their view to be upheld in "their" territory. For example, my "offensive" notes were in a comment in a thread I started. If they were in the title it breaches into other's territory. But even with that, it does not mean a person has to respect such a view. It just means if the views do not match you can expect reactions.
As for not being technical as stated (and some are discussing in the Lounge), there seriously seems to be something wrong with this forum in how QA is handled. This stems from non technical issues, thus it has become the topic. Probably not the appropriate medium though but happenstance has brought it to that.
