Hi,

I learned from Vishesh a few days ago that in order to see the running queries in virtuoso,
one can use isql-vt and type status();

However this has issues.

First problem: giving it the port number where virtuoso-t is running. This can be automated
using a script like this: http://www.davidfaure.fr/kde/virtuoso_isql_debug (at least on OpenSUSE).

Second problem: the queries are shown truncated. This can be fixed by applying the
attached patch to virtuoso.

http://kdeatopensuse.wordpress.com/2011/11/09/debugging-nepomukvirtuosos-cpu-usage/
seems to have other hints, including getting the current query from nepomukserver using dbus,
which is an alternative solution.
