Re: How to do profiling in MAL interface?

11 Apr 2016

      Hi Martin,

Thanks. stethoscope does do some work. But since it is for online
monitoring, it is inconvenient for offline analysis of trace profiles.
After reading more docs on the web, I find Tachograph comes closest to what
I want.
A minor problem is that the schema of the generated files (.trace, .csv,
.json) is not given.
Somehow I have to guess. And seems that each file format covers a different
subset of attributes.

You better consider using the stethoscope for doing this kind of analysis.
The documentation need some updates.

Hi all,
I know I can use the TRACE SQL command. But I want to do it in the
"-lmal" interface (because I massaged the MAL plans a bit to test my
research ideas).

https://www.monetdb.org/Documentation/Manuals/MonetDB/Modules/profiler )
doesn't match the source code. I can't find the profiler.activate() or
