Re: Database Metrics
Title: Database Metrics Hello Yuval Arnon I will use three graphs: 1) Number of SQL statements executed per day. 2) Mean response time. 2) CPU usage per day. In both cases add a reference point that is the mean of the last 30-40 days so they can see any abnormal behavior. The space statistics are for you and use them only quarterly for management. If you can add a graph for important applications.

RE: Database Metrics
A few idears... Summarize total database size growth (growth of the actual data, not the object) and deltas by tablespace. Summarize actual object growth (object as opposed to size, contrast against overall total tablespace space) and deltas. Create a benchmark query that runs at various times during the day. Plot the run results and provide an average run time report and graphed plots. Problem/on-call reports with problem summaries (this can be real telling)... Average backup run time for the week. Plot the following: number of active users for database. HWM concurrent users connected for each day. HWM for concurrent transactions for each day. -Original Message- Sent: Monday, April 29, 2002 1:23 PM To: Multiple recipients of list ORACLE-L Hi, I am looking for ideas on what kind of metrics the DBA group should provide the management on a weekly basis so they can understand how the databases are evolving over time.

RE: Database Metrics
Robert - Excellent ideas! To bounce off your ideas, one thought is to find out what matters most to the users and create some statistics based on that. For example, one of our applications has a process that performs really badly during the peak season. Some fixes have been tried, but management doesn't want to expend the effort to fix it. However, the application does write statistics to a log, so I load those values into an Oracle table and report the results to the management. They feel it works as an indicator for many other factors. Basically a canary in a coal mine. Because it is an indicator that means something to them and they can relate to, it is worth expending a fair amount of effort. Dennis Williams DBA Lifetouch, Inc.

RE: Database Metrics
Title: RE: Database Metrics I use these two to show the number of tables created and tables modified by month. In our case, the number of new tables and DDLs has been climbing as the database is getting more complex. On a graph, the lines are climbing upward which is something management can understand. select TO_CHAR(Created, 'MM') MonthCreated, Count(TO_CHAR(Created, 'MM')) TablesCreated from dba_objects where object_type = 'TABLE' group by TO_CHAR(Created, 'MM') order by 1; select TO_CHAR(LAST_DDL_TIME, 'MM') MonthModified, Count(TO_CHAR(LAST_DDL_TIME, 'MM')) Tables DDL'ed from dba_objects where object_type = 'TABLE' group by TO_CHAR(LAST_DDL_TIME, 'MM') order by 1; Jerry Whittle ACIFICS DBA NCI Information Systems Inc.
