That Which is Monitored, Improves

1. That Which is Monitored, Improves Dan McKee & Megan May Sakai Metrics at Indiana University

2. Sakai Metrics at Indiana University • At Indiana University we believe,That Which is Monitored, Improves • How does Indiana do this? • Extended Performance Metrics [EPM] • Objective today: to present three such metric categories that are in use today • Course site tool usage metrics • Project site tool usage metrics • Database performance metrics Sakai Metrics at Indiana University

3. Sakai at Indiana University • Background • Sakai is called Oncourse CL at Indiana University • Supports over a 100,00 users • Measuring Migration • It runs on a Virtualized IBM AIX (Unix) Server • Its Database Management System is Oracle 10g • Size is approximately 60 Gbs • The typical number of CL Sessions at any one point in time is around 5,000 Sakai Metrics at Indiana University

4. EPM*: Sakai Tool Usage Metrics (* Extended Performance Metrics) • Background • Designed to be Database Platform Independent • Based upon data contained within the Sakai Application/Database • Metrics are populated via PERL scripts • Data Structures are: • Designed to ease reporting and sql query construction • Compatible with a variety of SQL Tools Aqua Data Studio, DBVisualizer, SQL Developer,SQL4X and others • Tool Usage Metric DDL is available at: • http://confluence.sakaiproject.org/confluence/x/cKc (see fileepm_tool_proj_20061102_ddl.sql) • SQL scripts and Perl scripts used to build and maintain EPM are available at the above link.

8. EPM: SQL to Populate Tool Usage • Example SQL used to extract Tool Usage • SQL to Extract Tool Usage for Syllabus [SYL] • select substr(site_id,1,2)TM, '20'||substr(site_id,3,2)YR, substr(site_id,6,2)CMP, count(distinct(Site_Id)) CNTfrom onc.sakai_site_propertywhere site_id like 'FA06%’and SITE_ID in(select CONTEXTID from onc.sakai_syllabus_itemwhere ID in (select surrogatekey from onc.sakai_syllabus_datawhere not (title is null)))group by substr(site_id,1,2),substr(site_id,3,2),substr(site_id,6,2); • File containing complete sql for extracting Tool usage is available at: • http://confluence.sakaiproject.org/confluence/x/cKc(see file epm_tool_upd_qry.sql) • Perl script used to extract and populate the Tool Usage Metrics is available at the above link • (see file update_epm_tool_ft.pl) Sakai Metrics at Indiana University

EPM: Sakai Project Metrics • Background • Designed to be Database Platform Independent • Based upon data contained within the Sakai Application/Database • Metrics are populated via PERL scripts. • Data Structures are: • Designed to ease reporting and sql query construction • Compatible with a variety of SQL Tools • Aqua Data Studio, DB Visualizer, SQL Developer, SQL4X, and others • Project Count Metric DDL is available at: • http://confluence.sakaiproject.org/confluence/x/cKc(see file epm_tool_proj_20061102_ddl.sql) • SQL scripts and Perl scripts used to build and maintain EPM are available at the above link Sakai Metrics at Indiana University

18. EPM: SQL to Populate Project Metrics • Example SQL used to extract Project Counts • Project Count for Syllabus [SYL] • select count (site_id) PRJ from onc.sakai_sitewhere type = 'project' and SITE_ID in (select distinct (CONTEXTID) from onc.sakai_syllabus_item where ID in (select surrogatekey from onc.sakai_syllabus_data where not (title is null))); • File containing complete sql is available at: • http://confluence.sakaiproject.org/confluence/x/cKc(see file epm_proj_upd_qry.sql) • Perl script used to extract and populate the Project Count Metrics is available at the above link • (see file update_epm_proj_ft.pl) Sakai Metrics at Indiana University

20. EPM: Oracle Database Performance Metrics • Background • Oracle Database Performance Metricsare NOT Database Platform Independent-- Oracle 10g Specific • Based upon data contained within: • Oracle Automatic Workload Repository [AWR] • Other External Sources • Database Extended Performance Metrics are populated via Perl. • Data Structures are: • NOT Specifically designed to ease reporting and sql query construction(these structures are supplied by Oracle not Sakai) • compatible with a variety of SQL Tools • Aqua Data Studio • DB Visualizer • SQL Developer • SQL4X • And others • Oracle Database EPM DDL is available at: • http://confluence.sakaiproject.org/confluence/x/cKc (see file epm_ora_db_ddl.sql) • SQL scripts, Perl scripts and documentation used to build and maintain Database EPM are available at the above link. Sakai Metrics at Indiana University

21. EPM: Oracle Database • Metrics from Oracle’s AWR include: • Buffer Cache Hit Ratio -- AWR • CPU Usage Per Sec -- AWR • CPU Usage Per Txn (server) • Current Logons Count • Cursor Cache Hit Ratio • Database CPU Time Ratio • Database Time Spent Waiting • Host CPU Utilization (%) • Library Cache Hit Ratio • PGA Cache Hit % • RAM USAGE • Response Time Per Txn • RowCache Hit Ratio • SQL Response Time (%) • Shared Pool Free % • Sorts in Memory Sakai Metrics at Indiana University

22. EPM: Oracle Database • Metrics Whose Source is External to Oracle’s AWR include:(Metrics populated from external sources via Perl scripts) • CL Sessions -- Sakai Database • CL User Count -- Sakai Database • Size of Database -- Sakai Database • Percent Used -- Sakai Database • Space Used -- Sakai Database • CPU USAGE -- System Administration / AWR • RAM USAGE -- System Administration / AWR Sakai Metrics at Indiana University
