Hi All,

I am currently working on porting dynamix to Pharo. Maybe I can combine with DTrace somehow. We hat quite a few visualizations in mondrian for dynamic analysis and feature analysis. If the weather keeps up as it is I should be a good way into the work by the end of the week.

Cheers.

Hi,

I am not sure I understand what kind of information one could get from DTrace. Is it a trace? If so, it would be great to populate Dynamix from it and then build analyses on top.

Cheers,
Doru

Hi Mariano,

I read Adrian's blog, this sounds very appealing. I will give a try to generate a mondrian visualization. That could be cool.

I think DTrace should be part of Moose. Maybe we can add a section on dynamic analysis that would contain DTrace and Spy?

Cheers,
Alexandre

Hi folks. Today Adrian released an integration between the Squeak/Pharo VM and DTrace. I read his post and the code and seems VERY interested. I know very very little about Moose, but I guess if moose wants to move on, it should start to analyze more the runtime world. For such purpose, it will requiere PROBABLY (almost sure) a particular VM.  For example, what I plan to do now (playing with DistributionMap and used/unused objects) will requiere my own VM. In this case of Adrian too. So....

The Adrian's post can be found here: http://www.adrian-lienhard.ch/blog
Please take a look. Not necessary to the implementation details but to the features it can you you.

Finally, read the last sentence: "DTrace by itself does not provide visualizations but since its output can be formatted as required (using printf) and piped into a file, one can feed the data to a visualization tool (e.g., print output in MSE format, import it into Moose, and create interactive visualizations with Mondrian)."

Cheers

Mariano
