  • Adapt monitoring pages to the new LEMON website.

5 Nov 2007

15 Oct 2007

  • Stress tests with Balys on Oracle 11g
  • COOL performance : SVMC Bulk Insert (task #5654)

11 Sep 2007

01 Aug 2007

  • COOL 2.2.0 was released in July, we can test the differences between this release and the previous one
  • UTBM Report

26 Jun 2007

25 Jun 2007

  • did some tests with flashback table scripts... need more feedback from Gianni & Andrea

20 Jun 2007

18 Jun 2007

  • Calculate COOL data overhead (index...) : factor of 3.5 ... more details following : CoolDataOverhead
Instead of 300GB per year (only the payload) we reach almost 950GB

12 Jun 2007

  • Use PVSS, PVSS2COOL in order to test them. Investigate documentation and Andrea's log.

11 Jun 2007

  • Inserted different data sets for performance tests (Atlas DCS data => CoolInsertionTest). Space problem on CMSONR where the data is stored (not enough space to store all different data sets so the tests will be started with 7 days, 25d, 50d, 100d and 150d in a first time, we'll go with 1-year data after).

06 Jun 2007

04 Jun 2007

  • NEW: if num clients == 0 then stop test and report ? => Define a condition for the client to stop in pyCoolClient, means define a new parameter ?

30 May 2007

  • Develop & use a C++ client for COOL bulk storage (in order to fill 1 year data first then for performance testing)

22 May 2007

  • FIX: merge stopClients et startTest (manager script)
  • FIX: change the way to calculate the throughput in the reporter
  • use mid-range servers : CoolInsertionTest
  • kick out the threads => use fork()

08 May 2007

  • BUG: Problem with pyCoolClient, increasing number of clients do not increase number IOV/s => python problem (threads cannot execute properly on multi cpu machine => back to processes)
  • Persistency thread/proc test : same problem => python threads

07 May 2007

  • NEW: use the variable isThreaded to chose threads or processes
  • COOL 5000 prefetch test : no meaning full improvement

27 Apr 2007

  • NEW: modify the report script to accept new changes (need more changes)

26 Apr 2007

  • CHANGE: way to calculate average since test start, impact on client, startTest and report
  • NEW: use cvs files instead of log files

25 Apr 2007

  • INFO: BUG (not fixed) Segmentation fault with COOL_2_1_1 on slc4_ia32_gcc34 on exit.

24 Apr 2007

  • INFO: pb w/ threads & COOL => there is a limitation on the throughput, perhaps due to system calls.

22 Apr 2007

  • NEW: Documentation : Introduction
  • NEW: Create a clean sql script that create ST_REPORT account and the views

20 Apr 2007

  • FIX: Compute min, avg, max CPU utilization directly in the SQL statement
  • FIX: Change the graphs presentation (more readable)

19 Apr 2007

  • NEW: Add the number of clients to the metric graphs
  • NEW: In report page add links at the top (to client & server nodes)
  • FIX: Remove the buggy metric 0 (for time ellapsed since test start)

18 Apr 2007

  • NEW: Add to the live reporter the wait events stats
  • NEW: Add to the report script the new graphs (cpu, wait, metrics)
  • FIX: Remove the avg CPU and total load on live reporter
  • FIX: Change the code of pyCoolClient to new code by Andrea (4core test). Result: clients don't use the same connection anymore
