Chapter 8 - Extended Insight
8.1 Extended Insight: the big picture
pureQuery delivers extensive client monitoring capabilities via its Extended Insight feature
in conjunction with IBM’s Optim Performance Manager Extended Edition product. Extended
Insight gives the DBA insight into the performance of previously obscured data access
layers that affect data access application performance. For data access applications written
using pureQuery API’s, pureQuery Client Optimized applications, and JDBC or CLI
applications using supported JDBC or CLI drivers, Extended Insight delivers database
client, application server, and network statistics side by side with database statistics from
traditional database monitoring tools. In addition to statistics, pureQuery also supplies
application metadata that works in conjunction with Extended Insight data to provide quick
identification of applications executing problem SQL.
In a multi-tiered application environment, DBA’s may be asked to “solve the problem” of a
slow response time for a running application, before it is even known whether the problem
is in the database or somewhere in the many layers between the application and the
database. In this situation, DBA’s may have little information to help them identify which
parts of the application are issuing problematic SQL. Extended Insight helps DBA’s who
are faced with problem determination in a multi-tiered environment. It increases visibility
into the end-to-end stack so the DBA can quickly pinpoint the layer in the stack or identify
the application that is causing problems in a running, monitored system. Extended Insight
capabilities are presented seamlessly integrated in Optim Performance Manager along with
the traditional tools DBA’s use for database monitoring and troubleshooting.
8.2 Common Problems in Multi-Tiered Monitoring
Application-centric DBAs who support databases for dynamic data access applications in multi-tiered
environments face a common set of problems resulting from the large number of layers between an
executing application and the database.
