Wish List

Integration with other monitoring tools (i.e. Keynote or Gomez) to help debug their transactions

Drill-up : double click on a function in JavaScript source should show me everything where this function is involved. Stack, calls, times, etc ... I can sense this information is all "behind" but it is not possible to reach it at the click of a button.

• More specific Filters please. Plus possibility to save filter settings to filter sets.

      We do AJAX analysis spearate from GUi analysis (which images are loaded, etc.).

• more specific mouse event filters. MouseMove does not interest most of the time, only click events.
• correlation of an event leading to an ansyc call plus it's callback.
  

1. AJAX Memory *and CPU* diagnostics (Browser, DOM)!!!  DOM and VML in IE7/IE8 are CPU and memory hogs. Show in timeline or otherwise correlate with user events and network requests/responses.

2. Summary statistics grouped by URL for network requests (total, avg, median, stddev, median: bytes, bytes/sec, etc)

3. Record and playback of user keyboard/mouse events like Selenium or integrated with it.

From Olivier Percebois-Garve:
"I would be nice if you would consider adding a "stop recording" button. I've been looking for it during a long time, plus I suspect it is also the reason why dynatrace is very slow to "wake up" after a while."

Great program!  It has been quite helpful in helping to find bottlenecks in code.

It is quite useful that it is possible to select rows in the Time Chart of the PurePaths screen and then copy them to the clipboard and then paste into a text editor (as XML).  However, when we do this, we only get the "Start" and "Duration" figures.  I'd like to also be able to get the breakdown of the "duration", into "Wait" "DNS" "Connect" "Server" "Transfer", as well as the "Response Size" in bytes.  I know that the "copy" is meant to be generic, encompassing all of the types of network activity, but it should be possible to do this.  Maybe as an additional column that contains activity-specific information?

Thanks for the great program and I look forward to continue using it in the future.

It would be nice to be able to sort the Sessions by name or date/time. This would allow me to group my test cases together. It would also be nice the the 'duration' field was populated with something other than 0 on the 'summary' (right click on session). Thanks!

It would be convenient to have an indication of the current level of zoom applied to a timeline.

I often take screenshot of small portions of the timeline in order to document the effect of different versions of our code. Having a indication of the level of zoom would help me to use the same scale in every screenshot.

Good to see Firefox support will be added in the next upcoming release.

And it's good to see requests for Chrome to be supported. I would extend this and sugguest support for WebKit (so Chrome & Safari)

But lastly, and probably most awkward to implement would be be Apple Mac support? I use a Mac for development at home and a PC at work. I know lots of PHP developers who work on Macs and would appreciated the AJAX edition being compatible (me included).

1. Show the time labels at the top of timeline. When many hosts are involved in the page the labels are scrolled outside of the view. Alternatively make time labels visible regardless of scrolling.

2. Needs more detail regarding the renedering activities (reference to specific HTML/css would be nice) to troubleshoot inefficient HTML layouts, etc.

3. There are periods of high CPU consumption in the browser when it's not clear what is going on because theis no rendering activities, downloads or JavaScript. Need more detail regarding these "blank" areas.

4. Allow the UI to show the downloads from the same host on multiple rows instead of the overlapping display on one row. I know you have the tooltips, but display on multiple lines is easier to visualize.

Hi

another small suggestion, it would cool to be able to export the  "Contributor" and "Stack Element" Data to excel the same way we can for the "Activity" frame. (it is currently not possible to select multiple lines)

Hi

- I wish if I can compare the sessions and the pages, so I can easily identify the improvements on my application. 

Hi

I noticed something today in the purePaths view :
The duration includes asynchroneous function (i.e setInterval or setTimeout).

So if some code waits 1000ms and then get executed in 10ms, the purePaths reports 1010ms.

Whilst it is true that it taken 1010ms for the function to complete, it is not 1010ms of "blocking" execution, but only 10ms. So at a first look such function appears to be have a big impact on performance, but in fact it is neglectible.

So my wish is to have a display of the "really blocking execution duration" in the purePaths.

+1 for the suggestion by Ilya: " it would be nice to be able to mark the time when page started showing up on the screen in timeline. Not page_load event, but just as soon as some rendering started"

Also are you planning on supporting the export of performance data in the HAR format? http://groups.google.com/group/firebug-working-group/web/http-tracing---export-format

I haven't found a way to get dynaTrace Ajax Edition to indicate whether a file is compressed or not (gzip or deflate).  All downloaded files sizes on the Networks tab seem to show the uncompressed file size even if the file was compressed.  This makes it hard to determine whether or not compression is functioning as expected on the Web Servers or Load Balancer.  Check out the http packet sniffing tool Charles for a great implementation of this.  They even tell you what % compression was achieved.

Hi Andreas

a few points I have noticed :

When the timeline is zoomed a lot, it is very hard to scroll : either the arrows become very slow or if the cursor is used, then it is too fast. A "hand" feature allowing to drag the timeline would be very convenient.

Another point would be to add an option to make the text of the marks always visible. That would help taking screenshots with this information.

Also the marks could get their timing in their current execution block.

When exploring the execution block, it would be nice to see the marks appears as well.

Hi

I have some more wishes
 (and may very well have more soon since I'm now our "dynatrace contact point" and I am gathering feedback).

1. export of subparts of the purePath. 
It would be great if we could do "Show selected  node as root" and then "export". It makes really sense for us, since we have very long timelines and are often interested in only a small part of it.

2.I'd be interested in a "show most expensive native functions" feature. In fact when I explore the purePath, I often dive until I can find what is the native function that takes time. On some action we have hundreds of calls to getElementById. Dynatrace could have a feature tu underline this fast. It would be great if it could display on the timeline.

that's it for now, wish you a great weekend
Olivier

One more for the road.

Without to dig in the server-side activity, I would be interested in having more details on the network activity.
HttpWatch provides a distinction between the "transfert" part and the "receive" part. We noticed that several factors can affect the "receive" part, for instance the size of the response or the cpu activity at that moment. I wished I could have some more details on that.

Hi,

just a couple of thoughts.

I have some pages which load things in background, after onready and onload, but don't display anything (ie: analytics tracking javascript). In this case I usually use "time to last render" as a Key Performance Indicator, do you think it's possible to add it to KPIs ?

I don't know if it's traceable, but is it possible to add (in timeline) when the page is not interactive? When it's blocked by intensive javascript or by loading of external resources (inevitable document.writes as in advs).

Thank you very much for your work.

I would like to see the ability to view the contents of AJAX requests. Currently, the tool captures the content of the AJAX response but not the content of the request.

When do you plan to add the FireFox support? Apparently you have a great tool here but what I really need to use it is cross-browser support, at least for FF and IE.

It would be fantastic to be able to see which DOM nodes are being affected by repaint or redrawing. So, if a CSS change happened at one level and it's causing a repaint at a higher level, it'd be great to be able to see this. 

Since I am working on a news website, I am looking more at initial load. One very important apsect of this, is the number of connections that the browser is able to open. To visualize this, it would be nice to be able to see on multiple line the network activity. Currently, downloads are displayed over eachothers, it makes it difficult to see the detail of each download. 

Alternate timeline view?

I've been using a few different tools to evaluate the performance of my web application.  I've been using dynatrace to delve into the nitty-gritty details of my application which is great because I can see every thing that is going on. 

I've also been using a tool called HttpWatch professional (not free) that shows less information than dynatrace but it presents that information in a very clear and concise way.  It lets me see the relationship of request to actions.  It helps to highlight potential issues in a way that "pops."  I'd like to see a similar layout for dynatrace, maybe an alternate way of viewing the timeline?

IE9 support.

I use Linux a my primary O/S all day everyday.  I currently use the dT Client on OpenSuSE 11.3 and run the dT Server on SLES 11.1  Now that dT AJAX supports FireFox, when will Linux be supported? 

Please...memory diagnostics. Even if you start with something simple. Chrome has some support, but it looks like it can only take heap snapshots of relatively small heaps.

Definitely something that my company would gladly pay for!

Why doesn't the "Content-Encoding:gzip" show up in the Response Headers when receiving gzipped compressed data from the web server? Can it also show the compressed and uncompressed size?

It would be nice in the Ajax edition to be able to specify the name of a page in the reports. We have sites where the URL is the same whether you are logged in or not, but the user experience and features on the page are different. At present, it is difficult to keep the results of the logged in users separate from the logged in users. If there was a field that we could type into (similar to the add Mark field), it would be nice to have the contents of the field used as a prefix to the name of the URL that is being tested in the reports.
