Thank you for the comment.

It sounds like you put together a comprehensive monitoring solution. Thank you for sharing – it is always interesting to hear how other people are tracking performance issues.

In the VBS category on this blog you will find a couple of scripts that tie directly into several chapters of the book. Some of those scripts might give you one or two additional ideas for additional monitoring for version 2 of your DB monitoring setup – web-based drill down into problematic sessions and their SQL statements, for instance.

our current (first version of) monitoring gathers
1.) CPU / IO / memory: v$osstat, v$filestat/v$tempstat, v$pgastat
2.) transactions / wait events / time model: v$sysmetric (group_id = 2 for user calls, block gets, redo, user tx), $sys_time_model, v$system_event
3.) application-specifics / SQLs: v$tempseg_usage, v$session, v$sql, v$sqlarea and “individual” application instrumentation/logging (e.g. start/end time of ETL loads, start/end time report generation)

Most of the data is collected every minute by a PLSQL package. Analysis is done by data export & Excel.

Thanks for stopping by my blog. Great that you found helpful ideas in the book. Do you want to share a description of what you put together for DB monitoring?
