Thanks, did not read the doc... sorry
Btw,
I found a strange case leading to a virtuoso crash when querying this
view, I can reproduce this way :
ok SQL :
SELECT ql_id,ql_start_dt,ql_client_ip, ql_error,ql_sqlstate,(100 *
ql_thread_clocks / ql_rt_clocks) as
cpu_percent,ql_rt_msec,ql_c_clocks,ql_c_msec,ql_thread_clocks,ql_disk_wait_clocks,ql_qp_threads,ql_c_memory,ql_text
FROM sys_query_log
WHERE qrl_file =
'/usr/local/virtuoso-opensource/var/lib/virtuoso/db/virtuoso.qrl'
AND qrl_start_dt = cast ('2016-05-13 00' as datetime)
AND qrl_end_dt = cast ('2016-05-13 23' as datetime)
and ql_user='SPARQL'
crash SQL : the same as abovee, just add an order by clause at the end
on ql_thread_clocks column :

Hi Thomas,
You analyse the Query log by querying the special “sys_query_log” view
in Virtuoso as detailed at:

Hello,
I activated QueryLog = virtuoso.qrl in my
virtuoso.ini to collect and analyze logs for queries performed
against our Virtuoso instance but i've problems reading special chars
in the results :
- is the file format simple text ?
- does it use compression ?
- proprietary format ? encoding ?
Thanks,
