Hi Martin,

My Monetdb version is MonetDB Database Server v1.7 (Jan2014-SP2). I'm using Ubuntu 12.04 LTS Precise.

My Stethoscope works perfectly displaying valuable information. However, I have some confusion about the metrics. Why some MAL statement has non-zero 'blk.reads' and 'blk.writes' but their rbytes and wbytes are zero? What exactly does these memory related metrics mean?

Thanks!

Hi all,

I need to have a visual view of the execution detail of each thread in monetdb so I wish to use Tomograph. I followed this https://www.monetdb.org/Documentation/Manuals/MonetDB/Profiler/tomograph and have installed all required pacakges. But Tomograph does not respond when I finished my queries. All its outputs are empty. However, my Stethoscope works perfectly.

Is there anything not listed in the Tomograph documentation that needs to be done to get it work?

Thanks!

Xuntao
