The Transaction Analysis tab represents the response time, which has a direct effect upon the user experience, of a business application as a histogram. AppDynamics classifies the response time based on the patterns of business transactions.
Accessing the Transaction Analysis Tab
How Transaction Analysis is Organized
The vertical bars represent a slice of time against which AppDynamics has gathered performance metrics such as response time. The bar metrics are stacked and color-coded according to the response times of the requests, as:
- Normal - green
- Slow - yellow
- Very Slow - red
- Stalls - grey
You can see details by hovering over different parts of the graph.
Use the Time Range menu in the upper right to change the time period for which data is displayed.
Average Response Time
The blue line represents the average response time. Spikes in response time indicate that the user experience is degrading.
The average response time dynamic baseline appears as a dotted line.
Statistics for a Time Slice
You can select a time slice by dragging your pointing device over the histogram. This displays a window that summarizes the key performance indicators and transaction scorecard over the selected time slice.
You can click Select as Global Time Range to reset the time range used in other screens in the AppDynamics UI to the time slice that you have set in the transaction analysis screen. This initiates a reload of the dashboards.
Click the Events tab to see the events generated over the selected time period. See Events.
