Red Samurai ADF Performance Audit Tool v 3.2 - Large Fetch and Full Scan Audit Optimizations

Red Samurai ADF Performance Audit tool was updated with new features. Current update v 3.2 is focused on improvements for Large Fetch issues auditing, additionally we are able to track Full Scans (when user is fetching all rows and row count exceeds a threshold).

There are two additional threshold parameters introduced - WAT (Wait Activation Time) and WFT (Wait Fetch Time). These two are used to track long activation and fetch times in more accurate way. For simplified migration process from v 3.1, if no configuration is set in the database - default values are applied:

Large Fetch issue reports time it took to fetch rows, before it was reported only a number of rows fetched:

Audit tool knows how to track Full Scan - issue when user is fetching all rows and number of fetched rows exceeds Large Fetch threshold. This is useful, as it allows to understand specific cases, where we could optimise ADF code and potentially avoid fetching all rows:

Full Scan is reported together with all other issues, it is included to be a part of Performance Analysis graph:

Slow Query drill down was updated, to display VO instances with most recent slow query issues first (in red - number of issues in the recent 5 days):

Table with most recent Slow Query issues was redesigned to display issues in better ordered way. Today issues are displayed first, then issues from Yesterday, followed by Latest in 5 days and then All issues. Average time for each slow VO instance is calculated and displayed:

Daily Trend for VO instance was introduced in v 3.1, now tool also supports Monthly Trend - this allows to understand performance tuning impact better:

Large Fetch drill down was updated, it displays proportion of Large Fetch and Full Scan issues. List of VO instances reported with Large Fetch issues is redesigned in the similar way as for the Slow Query:

Today, Yesterday, Latest (5 days), and All issues are displayed. Average time is calculated and displayed for VO instance large fetch. Monthly Trend is calculated in the similar way as for the Slow Query.

Graphs displaying large number of days are configured with zooming - Daily Transactions and Logged Users graphs support zooming now:

User can zoom in data, this helps to analyse data points in specific days:
