Aggregated Traces table

The Aggregated Traces table, on the top right side of the view, lists a series of aggregate traces over the time period for the selected requests. Aggregate traces are created using the aggregate time interval, which is set to one (1) hour by default. They contain information about all of the traces collected within the aggregate time interval, and are useful for investigating a group of single traces all at the same time. Aggregate traces are identified by the start time of the aggregation. There is only one aggregate per interval.
 
Table 18. The Aggregated Traces table contains the following columns:
Column Name
Description
Time
Start time of the aggregation.
End Time
End time of the aggregation.
Length
Total time of all requests within the aggregation to complete.
Traces Included
Total number of single traces included in the aggregate trace.
Execution Time (s)
Avg, Max, and Total
Average, maximum, and total time taken by the request to complete.
Exceptional Exit Count
Number of requests which exited with an exception.
Incomplete Count
Number of requests which have timed out.
Avg Execution Time by Component Technology (s)
Average execution time spent using the specified technology.
For more information, see Viewing breakdowns.
Avg Execution Time by Tier (s)
Average execution time spent in the specified tier, in seconds.
For more information, see Viewing breakdowns.
 
* 
NOTE: Some of the columns described are hidden by default. To add columns to the table, see Show/Hide table columns .

Single Traces table

The bottom right side of the Traces view contains data related to the single trace selected in the Traces table. This table is the list of individual single traces. Clicking on a time listed in this table displays the Single Trace view.
 
Table 19. The Single Traces table contains the following columns:.
Column Name
Description
Time
Start time.
Origin (Server)
Where the single trace started collecting.
Request URL
The URL of the traced request, truncated according to the URL transformation rules that are in use (default or custom).
For more information about URL transformations, see the topic Setting Rules for Transforming URLs in the Foglight for Application Servers Administration and Configuration Guide or help.
Execution Time (s)
The time the trace took to execute.
Response Time (s)
The amount of time, in seconds, that the trace took to complete.
Exceptional Exit
Whether this trace exited with an exception.
Incomplete
Whether this trace timed out.
HTTP Parameters
HTTP parameters are defined in the recording.config property file. If the single trace is using the specified parameters, information is displayed in the table. Click the HTTP parameter value to view more details in the FxV interface. For more information, see Viewing Request Data in FxV in the Foglight for Application Servers Administration and Configuration Guide.
Avg Execution Time by Component Technology (s)
Average execution time spent using the specified technology.
For more information, see Viewing breakdowns.
Avg Execution Time by Tier (s)
Average execution time spent in the specified tier.
For more information, see Viewing breakdowns.
Related Alarms
The number of alarms related to this single trace.
Actions
Shows or hide s the Actions icon.

NOTE: Some of the columns described are hidden by default. To add columns to the table, see Show/Hide table columns .

Performance charts

The Charts area contains graphs of the execution time and performance data for the selected single trace over the selected time period.
Component Technology Breakdown graph
The graph displays the Execution Time spent in each component technology (for example, Servlet, RMI Outgoing, HTTP, .NET Method, or ADO) for the aggregated traces.
Figure 28. To add or remove component technologies from the graph, click the customizer icon and select the technologies you want to see.
Overall Request Performance charts
There are three types of breakdowns:
•
Response Time - the amount of time, in milliseconds, that the request took to complete
•
Calls - the number of calls performed in the selected time period
•
Exceptional Exits and Incomplete - the number of incomplete requests and requests that exited due to an exception during the selected time period

Viewing breakdowns

Breaking the execution time down by component technology and/or tier allows you to visualize the relative performance and breakdowns of all traces in a set. You can show the amount of time spent in each component of the application server for every trace in a set (aligned by time), as well as which servers each trace crossed. This is helpful when you have defined custom components to track a set of packages and classes.
Selecting any number of these custom components and tiers displays the average execution time in the Aggregated Traces table and the total execution time for a component technology and tier in the Single Traces table. You can also see breakdowns in chart form for a given request type.
 
* 
NOTE: The Requests view displays charts with similar breakdowns. For more information, see Sampled Breakdowns tab .
To show breakdowns:
1
In the Traces view, click the customizer icon beside the table you want to modify (either Aggregated Traces or Single Traces). The Show columns menu opens.
2
Select the component technologies and tiers to display by clicking the check boxes.
3
Click Apply.
The specified breakdown columns are added to the Aggregated Traces or Single Traces table.
