Traditional Oracle Performance tools have failed to meet expectations.
Traditional Oracle applications tools have attempted, with limited success, to meet the performance management challenges of the business. These tools adopted the familiar "silo" approach, and were severely limited in their ability to correlate performance metrics across the application stack.

As with any "siloed" solution, data is collected within each respective application tier. Data from each tier of the application is gathered separately and un-correlated. A Subject Matter Expert (SME) must be added to the performance team further complicating the process to determine an appropriate solution. Quite often there is disagreement, indecision and communication issues among team members, which add time to the resolution process.

Often, there is a requirement for elite-level technical expertise to spend an excessive amount of time correlating multiple metrics to pinpoint the cause of performance degradation. With today's market and economy, this is a terrible waste of talent on an per-hour cost basis. This is like taking a thoroughbred race horse and putting it behind a plow.

Compounding the issue, many of the standard data collection technologies do not provide the information needed for rapid response. They typically have a large footprint, classifying them as intrusive, adding excessive overhead to the production environment. Therefore, they do not sample frequently enough (e.g. once every 5-10 minutes, at best) to gather enough information to perform meaningful analysis for the specific problematic time interval. This equates to missing performance metrics that mitigates the analysis.

Enter Indepth for Oracle
Indepth for Oracle provides fine-grain, highly detailed application profiling information at near-zero overhead. The development lab sets the expectation that the maximum overhead is between 1% and 3% of one CPU on the monitored server. Exhaustive, independent benchmarks have been conducted that have shown less than 1% of the the monitored server, even in the highest volume of transactions.
