8.21.1 Trace collection points of CDI and the trace information that can be collected

This subsection describes the trace collection points of CDI and the trace information that can be collected. The following two cases will be described separately:

When a combination of JSF 2.2 and CDI is used
When a combination of servlets and CDI is used

Organization of this subsection

(1) Trace collection points and PRF trace collection levels
(2) Trace information that can be collected

(1) Trace collection points and PRF trace collection levels

(a) When a combination of JSF and CDI is used

The following table describes the event IDs, trace collection points, and PRF trace collection levels.

Table 8‒123: Details of the trace collection points when a combination of JSF 2.2 and CDI is used
Event ID	No. in the figure^#	Trace collection points	Level
0xb002	1	When the reading of the JSF 2.2 settings required for using CDI starts	A
0xb003	2	When the reading of the JSF 2.2 settings required for using CDI ends (normal termination)	A
0xb004	3	When the JSF 2.2 preparations required for using CDI start	A
0xb005	4	When the JSF 2.2 preparations required for using CDI end (normal termination)	A
0xb006	5	When the EL assessment starts	B
0xb007	6	When the EL assessment ends (normal termination)	B

Legend:

A: Standard

B: Advanced

#:

Corresponds to the numbers in Figure 8-91 and Figure 8-92.

The following figure shows the trace collection points.

Figure 8‒91: Trace collection points when a combination of JSF 2.2 and CDI is used (when the JSF 2.2 settings are read and prepared)

Figure 8‒92: Trace collection points when a combination of JSF 2.2 and CDI is used (for EL evaluation)

(b) When a combination of servlets, filters, listeners, and CDI is used

The following table describes the event IDs, trace collection points, and PRF trace collection levels.

Table 8‒124: Details of the trace collection points when a combination of servlets, filters, listeners, and CDI is used
Event ID	No. in the figure^#	Trace collection points	Level
0xb008	1	When the generation of servlet/filter/listener instances starts	A
0xb009	2	When the generation of servlet/filter/listener instances ends (normal termination)	A

Legend:: A: Standard
#:: Corresponds to the numbers in Figure 8-93.

The following figure shows the trace collection points.

(2) Trace information that can be collected

(a) When a combination of JSF 2.2 and CDI is used

The following table describes the trace information that can be collected when a combination of JSF 2.2 and CDI is used.

Table 8‒125: Trace information that can be collected when a combination of JSF 2.2 and CDI is used
No. in the figure^#1	Event ID	Level	Information that you can acquire
No. in the figure^#1	Event ID	Level	Interface name	Operation name	Optional
1	0xb002^#2	A	`WeldFacesConfigProvider`	--	Context information of the Web container
2	0xb003^#2	A	`WeldFacesConfigProvider`	--	Entrance time
3	0xb004^#2	A	`WeldApplicationFactory`	--	--
4	0xb005^#2	A	`WeldApplicationFactory`	--	Entrance time
5	0xb006^#3	B	`WeldApplication`	--	--
6	0xb007^#3	B	`WeldApplication`	--	Entrance time

#1:

Corresponds to the numbers in Figure 8-91 and Figure 8-92.

#2:

The trace information for the reading of the JSF 2.2 settings required for using CDI and for the JSF 2.2 preparations required for using CDI is collected when the application starts.

#3:

The trace information for EL assessment is collected when FacesServlet is initialized and when Expression Language specified in JSF 2.2 is evaluated.

(b) When servlets are invoked from CDI

The following table describes the trace information that can be collected when servlets are invoked from CDI.

Table 8‒126: Trace information that can be collected when servlets are invoked from CDI
No. in the figure^#	Event ID	Level	Information that you can acquire
No. in the figure^#	Event ID	Level	Interface name	Operation name	Optional
1	0xb008	A	`CDIServiceImpl`	--	The following information is output: `Managed` class Class name Context root
2	0xb009	A	`CDIServiceImpl`	--	Entrance time

Legend:

A: Standard

--: Not applicable

#:

Corresponds to the numbers in Figure 8-93.

Note that the trace information is collected when the servlet/filter/listener interfaces are generated.
